============================= Netlink interface for ethtool ============================= Basic information ================= Netlink interface for ethtool uses generic netlink family ``ethtool`` (userspace application should use macros ``ETHTOOL_GENL_NAME`` and ``ETHTOOL_GENL_VERSION`` defined in ``<linux/ethtool_netlink.h>`` uapi header). This family does not use a specific header, all information in requests and replies is passed using netlink attributes. The ethtool netlink interface uses extended ACK for error and warning reporting, userspace application developers are encouraged to make these messages available to user in a suitable way. Requests can be divided into three categories: "get" (retrieving information), "set" (setting parameters) and "action" (invoking an action). All "set" and "action" type requests require admin privileges (``CAP_NET_ADMIN`` in the namespace). Most "get" type requests are allowed for anyone but there are exceptions (where the response contains sensitive information). In some cases, the request as such is allowed for anyone but unprivileged users have attributes with sensitive information (e.g. wake-on-lan password) omitted. Conventions =========== Attributes which represent a boolean value usually use NLA_U8 type so that we can distinguish three states: "on", "off" and "not present" (meaning the information is not available in "get" requests or value is not to be changed in "set" requests). For these attributes, the "true" value should be passed as number 1 but any non-zero value should be understood as "true" by recipient. In the tables below, "bool" denotes NLA_U8 attributes interpreted in this way. In the message structure descriptions below, if an attribute name is suffixed with "+", parent nest can contain multiple attributes of the same type. This implements an array of entries. Request header ============== Each request or reply message contains a nested attribute with common header. Structure of this header is ============================== ====== ============================= ``ETHTOOL_A_HEADER_DEV_INDEX`` u32 device ifindex ``ETHTOOL_A_HEADER_DEV_NAME`` string device name ``ETHTOOL_A_HEADER_FLAGS`` u32 flags common for all requests ============================== ====== ============================= ``ETHTOOL_A_HEADER_DEV_INDEX`` and ``ETHTOOL_A_HEADER_DEV_NAME`` identify the device message relates to. One of them is sufficient in requests, if both are used, they must identify the same device. Some requests, e.g. global string sets, do not require device identification. Most ``GET`` requests also allow dump requests without device identification to query the same information for all devices providing it (each device in a separate message). ``ETHTOOL_A_HEADER_FLAGS`` is a bitmap of request flags common for all request types. The interpretation of these flags is the same for all request types but the flags may not apply to requests. Recognized flags are: ================================= =================================== ``ETHTOOL_FLAG_COMPACT_BITSETS`` use compact format bitsets in reply ``ETHTOOL_FLAG_OMIT_REPLY`` omit optional reply (_SET and _ACT) ``ETHTOOL_FLAG_STATS`` include optional device statistics ================================= =================================== New request flags should follow the general idea that if the flag is not set, the behaviour is backward compatible, i.e. requests from old clients not aware of the flag should be interpreted the way the client expects. A client must not set flags it does not understand. Bit sets ======== For short bitmaps of (reasonably) fixed length, standard ``NLA_BITFIELD32`` type is used. For arbitrary length bitmaps, ethtool netlink uses a nested attribute with contents of one of two forms: compact (two binary bitmaps representing bit values and mask of affected bits) and bit-by-bit (list of bits identified by either index or name). Verbose (bit-by-bit) bitsets allow sending symbolic names for bits together with their values which saves a round trip (when the bitset is passed in a request) or at least a second request (when the bitset is in a reply). This is useful for one shot applications like traditional ethtool command. On the other hand, long running applications like ethtool monitor (displaying notifications) or network management daemons may prefer fetching the names only once and using compact form to save message size. Notifications from ethtool netlink interface always use compact form for bitsets. A bitset can represent either a value/mask pair (``ETHTOOL_A_BITSET_NOMASK`` not set) or a single bitmap (``ETHTOOL_A_BITSET_NOMASK`` set). In requests modifying a bitmap, the former changes the bit set in mask to values set in value and preserves the rest; the latter sets the bits set in the bitmap and clears the rest. Compact form: nested (bitset) atrribute contents: ============================ ====== ============================ ``ETHTOOL_A_BITSET_NOMASK`` flag no mask, only a list ``ETHTOOL_A_BITSET_SIZE`` u32 number of significant bits ``ETHTOOL_A_BITSET_VALUE`` binary bitmap of bit values ``ETHTOOL_A_BITSET_MASK`` binary bitmap of valid bits ============================ ====== ============================ Value and mask must have length at least ``ETHTOOL_A_BITSET_SIZE`` bits rounded up to a multiple of 32 bits. They consist of 32-bit words in host byte order, words ordered from least significant to most significant (i.e. the same way as bitmaps are passed with ioctl interface). For compact form, ``ETHTOOL_A_BITSET_SIZE`` and ``ETHTOOL_A_BITSET_VALUE`` are mandatory. ``ETHTOOL_A_BITSET_MASK`` attribute is mandatory if ``ETHTOOL_A_BITSET_NOMASK`` is not set (bitset represents a value/mask pair); if ``ETHTOOL_A_BITSET_NOMASK`` is not set, ``ETHTOOL_A_BITSET_MASK`` is not allowed (bitset represents a single bitmap. Kernel bit set length may differ from userspace length if older application is used on newer kernel or vice versa. If userspace bitmap is longer, an error is issued only if the request actually tries to set values of some bits not recognized by kernel. Bit-by-bit form: nested (bitset) attribute contents: +------------------------------------+--------+-----------------------------+ | ``ETHTOOL_A_BITSET_NOMASK`` | flag | no mask, only a list | +------------------------------------+--------+-----------------------------+ | ``ETHTOOL_A_BITSET_SIZE`` | u32 | number of significant bits | +------------------------------------+--------+-----------------------------+ | ``ETHTOOL_A_BITSET_BITS`` | nested | array of bits | +-+----------------------------------+--------+-----------------------------+ | | ``ETHTOOL_A_BITSET_BITS_BIT+`` | nested | one bit | +-+-+--------------------------------+--------+-----------------------------+ | | | ``ETHTOOL_A_BITSET_BIT_INDEX`` | u32 | bit index (0 for LSB) | +-+-+--------------------------------+--------+-----------------------------+ | | | ``ETHTOOL_A_BITSET_BIT_NAME`` | string | bit name | +-+-+--------------------------------+--------+-----------------------------+ | | | ``ETHTOOL_A_BITSET_BIT_VALUE`` | flag | present if bit is set | +-+-+--------------------------------+--------+-----------------------------+ Bit size is optional for bit-by-bit form. ``ETHTOOL_A_BITSET_BITS`` nest can only contain ``ETHTOOL_A_BITSET_BITS_BIT`` attributes but there can be an arbitrary number of them. A bit may be identified by its index or by its name. When used in requests, listed bits are set to 0 or 1 according to ``ETHTOOL_A_BITSET_BIT_VALUE``, the rest is preserved. A request fails if index exceeds kernel bit length or if name is not recognized. When ``ETHTOOL_A_BITSET_NOMASK`` flag is present, bitset is interpreted as a simple bitmap. ``ETHTOOL_A_BITSET_BIT_VALUE`` attributes are not used in such case. Such bitset represents a bitmap with listed bits set and the rest zero. In requests, application can use either form. Form used by kernel in reply is determined by ``ETHTOOL_FLAG_COMPACT_BITSETS`` flag in flags field of request header. Semantics of value and mask depends on the attribute.

They usually do not contain any message specific attributes. Kernel replies with corresponding "GET_REPLY" message. For most types, ``GET`` request with ``NLM_F_DUMP`` and no device identification can be used to query the information for all devices supporting the request. If the data can be also modified, corresponding ``SET`` message with the same layout as corresponding ``GET_REPLY`` is used to request changes. Only attributes where a change is requested are included in such request (also, not all attributes may be changed). Replies to most ``SET`` request consist only of error code and extack; if kernel provides additional data, it is sent in the form of corresponding ``SET_REPLY`` message which can be suppressed by setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header. Data modification also triggers sending a ``NTF`` message with a notification. These usually bear only a subset of attributes which was affected by the change. The same notification is issued if the data is modified using other means (mostly ioctl ethtool interface). Unlike notifications from ethtool netlink code which are only sent if something actually changed, notifications triggered by ioctl interface may be sent even if the request did not actually change any data. ``ACT`` messages request kernel (driver) to perform a specific action. If some information is reported by kernel (which can be suppressed by setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header), the reply takes form of an ``ACT_REPLY`` message. Performing an action also triggers a notification (``NTF`` message). Later sections describe the format and semantics of these messages. STRSET_GET ========== Requests contents of a string set as provided by ioctl commands ``ETHTOOL_GSSET_INFO`` and ``ETHTOOL_GSTRINGS.`` String sets are not user writeable so that the corresponding ``STRSET_SET`` message is only used in kernel replies. There are two types of string sets: global (independent of a device, e.g. device feature names) and device specific (e.g. device private flags). Request contents: +---------------------------------------+--------+------------------------+ | ``ETHTOOL_A_STRSET_HEADER`` | nested | request header | +---------------------------------------+--------+------------------------+ | ``ETHTOOL_A_STRSET_STRINGSETS`` | nested | string set to request | +-+-------------------------------------+--------+------------------------+ | | ``ETHTOOL_A_STRINGSETS_STRINGSET+`` | nested | one string set | +-+-+-----------------------------------+--------+------------------------+ | | | ``ETHTOOL_A_STRINGSET_ID`` | u32 | set id | +-+-+-----------------------------------+--------+------------------------+ Kernel response contents: +---------------------------------------+--------+-----------------------+ | ``ETHTOOL_A_STRSET_HEADER`` | nested | reply header | +---------------------------------------+--------+-----------------------+ | ``ETHTOOL_A_STRSET_STRINGSETS`` | nested | array of string sets | +-+-------------------------------------+--------+-----------------------+ | | ``ETHTOOL_A_STRINGSETS_STRINGSET+`` | nested | one string set | +-+-+-----------------------------------+--------+-----------------------+ | | | ``ETHTOOL_A_STRINGSET_ID`` | u32 | set id | +-+-+-----------------------------------+--------+-----------------------+ | | | ``ETHTOOL_A_STRINGSET_COUNT`` | u32 | number of strings | +-+-+-----------------------------------+--------+-----------------------+ | | | ``ETHTOOL_A_STRINGSET_STRINGS`` | nested | array of strings | +-+-+-+---------------------------------+--------+-----------------------+ | | | | ``ETHTOOL_A_STRINGS_STRING+`` | nested | one string | +-+-+-+-+-------------------------------+--------+-----------------------+ | | | | | ``ETHTOOL_A_STRING_INDEX`` | u32 | string index | +-+-+-+-+-------------------------------+--------+-----------------------+ | | | | | ``ETHTOOL_A_STRING_VALUE`` | string | string value | +-+-+-+-+-------------------------------+--------+-----------------------+ | ``ETHTOOL_A_STRSET_COUNTS_ONLY`` | flag | return only counts | +---------------------------------------+--------+-----------------------+ Device identification in request header is optional. Depending on its presence a and ``NLM_F_DUMP`` flag, there are three type of ``STRSET_GET`` requests: - no ``NLM_F_DUMP,`` no device: get "global" stringsets - no ``NLM_F_DUMP``, with device: get string sets related to the device - ``NLM_F_DUMP``, no device: get device related string sets for all devices If there is no ``ETHTOOL_A_STRSET_STRINGSETS`` array, all string sets of requested type are returned, otherwise only those specified in the request. Flag ``ETHTOOL_A_STRSET_COUNTS_ONLY`` tells kernel to only return string counts of the sets, not the actual strings. LINKINFO_GET ============ Requests link settings as provided by ``ETHTOOL_GLINKSETTINGS`` except for link modes and autonegotiation related information. The request does not use any attributes. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_LINKINFO_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ==================================== ====== ========================== ``ETHTOOL_A_LINKINFO_HEADER`` nested reply header ``ETHTOOL_A_LINKINFO_PORT`` u8 physical port ``ETHTOOL_A_LINKINFO_PHYADDR`` u8 phy MDIO address ``ETHTOOL_A_LINKINFO_TP_MDIX`` u8 MDI(-X) status ``ETHTOOL_A_LINKINFO_TP_MDIX_CTRL`` u8 MDI(-X) control ``ETHTOOL_A_LINKINFO_TRANSCEIVER`` u8 transceiver ==================================== ====== ========================== Attributes and their values have the same meaning as matching members of the corresponding ioctl structures. ``LINKINFO_GET`` allows dump requests (kernel returns reply message for all devices supporting the request). LINKINFO_SET ============ ``LINKINFO_SET`` request allows setting some of the attributes reported by ``LINKINFO_GET``. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_LINKINFO_HEADER`` nested request header ``ETHTOOL_A_LINKINFO_PORT`` u8 physical port ``ETHTOOL_A_LINKINFO_PHYADDR`` u8 phy MDIO address ``ETHTOOL_A_LINKINFO_TP_MDIX_CTRL`` u8 MDI(-X) control ==================================== ====== ========================== MDI(-X) status and transceiver cannot be set, request with the corresponding attributes is rejected. LINKMODES_GET ============= Requests link modes (supported, advertised and peer advertised) and related information (autonegotiation status, link speed and duplex) as provided by ``ETHTOOL_GLINKSETTINGS``. The request does not use any attributes. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_LINKMODES_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ========================================== ====== ========================== ``ETHTOOL_A_LINKMODES_HEADER`` nested reply header ``ETHTOOL_A_LINKMODES_AUTONEG`` u8 autonegotiation status ``ETHTOOL_A_LINKMODES_OURS`` bitset advertised link modes ``ETHTOOL_A_LINKMODES_PEER`` bitset partner link modes ``ETHTOOL_A_LINKMODES_SPEED`` u32 link speed (Mb/s) ``ETHTOOL_A_LINKMODES_DUPLEX`` u8 duplex mode ``ETHTOOL_A_LINKMODES_MASTER_SLAVE_CFG`` u8 Master/slave port mode ``ETHTOOL_A_LINKMODES_MASTER_SLAVE_STATE`` u8 Master/slave port state ========================================== ====== ========================== For ``ETHTOOL_A_LINKMODES_OURS``, value represents advertised modes and mask represents supported modes. ``ETHTOOL_A_LINKMODES_PEER`` in the reply is a bit list. ``LINKMODES_GET`` allows dump requests (kernel returns reply messages for all devices supporting the request). LINKMODES_SET ============= Request contents: ========================================== ====== ========================== ``ETHTOOL_A_LINKMODES_HEADER`` nested request header ``ETHTOOL_A_LINKMODES_AUTONEG`` u8 autonegotiation status ``ETHTOOL_A_LINKMODES_OURS`` bitset advertised link modes ``ETHTOOL_A_LINKMODES_PEER`` bitset partner link modes ``ETHTOOL_A_LINKMODES_SPEED`` u32 link speed (Mb/s) ``ETHTOOL_A_LINKMODES_DUPLEX`` u8 duplex mode ``ETHTOOL_A_LINKMODES_MASTER_SLAVE_CFG`` u8 Master/slave port mode ``ETHTOOL_A_LINKMODES_LANES`` u32 lanes ========================================== ====== ========================== ``ETHTOOL_A_LINKMODES_OURS`` bit set allows setting advertised link modes. If autonegotiation is on (either set now or kept from before), advertised modes are not changed (no ``ETHTOOL_A_LINKMODES_OURS`` attribute) and at least one of speed, duplex and lanes is specified, kernel adjusts advertised modes to all supported modes matching speed, duplex, lanes or all (whatever is specified). This autoselection is done on ethtool side with ioctl interface, netlink interface is supposed to allow requesting changes without knowing what exactly kernel supports. LINKSTATE_GET ============= Requests link state information. Link up/down flag (as provided by ``ETHTOOL_GLINK`` ioctl command) is provided. Optionally, extended state might be provided as well. In general, extended state describes reasons for why a port is down, or why it operates in some non-obvious mode. This request does not have any attributes. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_LINKSTATE_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ==================================== ====== ============================ ``ETHTOOL_A_LINKSTATE_HEADER`` nested reply header ``ETHTOOL_A_LINKSTATE_LINK`` bool link state (up/down) ``ETHTOOL_A_LINKSTATE_SQI`` u32 Current Signal Quality Index ``ETHTOOL_A_LINKSTATE_SQI_MAX`` u32 Max support SQI value ``ETHTOOL_A_LINKSTATE_EXT_STATE`` u8 link extended state ``ETHTOOL_A_LINKSTATE_EXT_SUBSTATE`` u8 link extended substate ==================================== ====== ============================ For most NIC drivers, the value of ``ETHTOOL_A_LINKSTATE_LINK`` returns carrier flag provided by ``netif_carrier_ok()`` but there are drivers which define their own handler. ``ETHTOOL_A_LINKSTATE_EXT_STATE`` and ``ETHTOOL_A_LINKSTATE_EXT_SUBSTATE`` are optional values. ethtool core can provide either both ``ETHTOOL_A_LINKSTATE_EXT_STATE`` and ``ETHTOOL_A_LINKSTATE_EXT_SUBSTATE``, or only ``ETHTOOL_A_LINKSTATE_EXT_STATE``, or none of them. ``LINKSTATE_GET`` allows dump requests (kernel returns reply messages for all devices supporting the request). Link extended states: ================================================ ============================================ ``ETHTOOL_LINK_EXT_STATE_AUTONEG`` States relating to the autonegotiation or issues therein ``ETHTOOL_LINK_EXT_STATE_LINK_TRAINING_FAILURE`` Failure during link training ``ETHTOOL_LINK_EXT_STATE_LINK_LOGICAL_MISMATCH`` Logical mismatch in physical coding sublayer or forward error correction sublayer ``ETHTOOL_LINK_EXT_STATE_BAD_SIGNAL_INTEGRITY`` Signal integrity issues ``ETHTOOL_LINK_EXT_STATE_NO_CABLE`` No cable connected ``ETHTOOL_LINK_EXT_STATE_CABLE_ISSUE`` Failure is related to cable, e.g., unsupported cable ``ETHTOOL_LINK_EXT_STATE_EEPROM_ISSUE`` Failure is related to EEPROM, e.g., failure during reading or parsing the data ``ETHTOOL_LINK_EXT_STATE_CALIBRATION_FAILURE`` Failure during calibration algorithm ``ETHTOOL_LINK_EXT_STATE_POWER_BUDGET_EXCEEDED`` The hardware is not able to provide the power required from cable or module ``ETHTOOL_LINK_EXT_STATE_OVERHEAT`` The module is overheated ================================================ ============================================ Link extended substates: Autoneg substates: =============================================================== ================================ ``ETHTOOL_LINK_EXT_SUBSTATE_AN_NO_PARTNER_DETECTED`` Peer side is down ``ETHTOOL_LINK_EXT_SUBSTATE_AN_ACK_NOT_RECEIVED`` Ack not received from peer side ``ETHTOOL_LINK_EXT_SUBSTATE_AN_NEXT_PAGE_EXCHANGE_FAILED`` Next page exchange failed ``ETHTOOL_LINK_EXT_SUBSTATE_AN_NO_PARTNER_DETECTED_FORCE_MODE`` Peer side is down during force mode or there is no agreement of speed ``ETHTOOL_LINK_EXT_SUBSTATE_AN_FEC_MISMATCH_DURING_OVERRIDE`` Forward error correction modes in both sides are mismatched ``ETHTOOL_LINK_EXT_SUBSTATE_AN_NO_HCD`` No Highest Common Denominator =============================================================== ================================ Link training substates: =========================================================================== ==================== ``ETHTOOL_LINK_EXT_SUBSTATE_LT_KR_FRAME_LOCK_NOT_ACQUIRED`` Frames were not recognized, the lock failed ``ETHTOOL_LINK_EXT_SUBSTATE_LT_KR_LINK_INHIBIT_TIMEOUT`` The lock did not occur before timeout ``ETHTOOL_LINK_EXT_SUBSTATE_LT_KR_LINK_PARTNER_DID_NOT_SET_RECEIVER_READY`` Peer side did not send ready signal after training process ``ETHTOOL_LINK_EXT_SUBSTATE_LT_REMOTE_FAULT`` Remote side is not ready yet =========================================================================== ==================== Link logical mismatch substates: ================================================================ =============================== ``ETHTOOL_LINK_EXT_SUBSTATE_LLM_PCS_DID_NOT_ACQUIRE_BLOCK_LOCK`` Physical coding sublayer was not locked in first phase - block lock ``ETHTOOL_LINK_EXT_SUBSTATE_LLM_PCS_DID_NOT_ACQUIRE_AM_LOCK`` Physical coding sublayer was not locked in second phase - alignment markers lock ``ETHTOOL_LINK_EXT_SUBSTATE_LLM_PCS_DID_NOT_GET_ALIGN_STATUS`` Physical coding sublayer did not get align status ``ETHTOOL_LINK_EXT_SUBSTATE_LLM_FC_FEC_IS_NOT_LOCKED`` FC forward error correction is not locked ``ETHTOOL_LINK_EXT_SUBSTATE_LLM_RS_FEC_IS_NOT_LOCKED`` RS forward error correction is not locked ================================================================ =============================== Bad signal integrity substates: ================================================================= ============================= ``ETHTOOL_LINK_EXT_SUBSTATE_BSI_LARGE_NUMBER_OF_PHYSICAL_ERRORS`` Large number of physical errors ``ETHTOOL_LINK_EXT_SUBSTATE_BSI_UNSUPPORTED_RATE`` The system attempted to operate the cable at a rate that is not formally supported, which led to signal integrity issues ================================================================= ============================= Cable issue substates: =================================================== ============================================ ``ETHTOOL_LINK_EXT_SUBSTATE_CI_UNSUPPORTED_CABLE`` Unsupported cable ``ETHTOOL_LINK_EXT_SUBSTATE_CI_CABLE_TEST_FAILURE`` Cable test failure =================================================== ============================================ DEBUG_GET ========= Requests debugging settings of a device. At the moment, only message mask is provided. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_DEBUG_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ==================================== ====== ========================== ``ETHTOOL_A_DEBUG_HEADER`` nested reply header ``ETHTOOL_A_DEBUG_MSGMASK`` bitset message mask ==================================== ====== ========================== The message mask (``ETHTOOL_A_DEBUG_MSGMASK``) is equal to message level as provided by ``ETHTOOL_GMSGLVL`` and set by ``ETHTOOL_SMSGLVL`` in ioctl interface. While it is called message level there for historical reasons, most drivers and almost all newer drivers use it as a mask of enabled message classes (represented by ``NETIF_MSG_*`` constants); therefore netlink interface follows its actual use in practice. ``DEBUG_GET`` allows dump requests (kernel returns reply messages for all devices supporting the request). DEBUG_SET ========= Set or update debugging settings of a device. At the moment, only message mask is supported. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_DEBUG_HEADER`` nested request header ``ETHTOOL_A_DEBUG_MSGMASK`` bitset message mask ==================================== ====== ========================== ``ETHTOOL_A_DEBUG_MSGMASK`` bit set allows setting or modifying mask of enabled debugging message types for the device. WOL_GET ======= Query device wake-on-lan settings. Unlike most "GET" type requests, ``ETHTOOL_MSG_WOL_GET`` requires (netns) ``CAP_NET_ADMIN`` privileges as it (potentially) provides SecureOn(tm) password which is confidential. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_WOL_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ==================================== ====== ========================== ``ETHTOOL_A_WOL_HEADER`` nested reply header ``ETHTOOL_A_WOL_MODES`` bitset mask of enabled WoL modes ``ETHTOOL_A_WOL_SOPASS`` binary SecureOn(tm) password ==================================== ====== ========================== In reply, ``ETHTOOL_A_WOL_MODES`` mask consists of modes supported by the device, value of modes which are enabled. ``ETHTOOL_A_WOL_SOPASS`` is only included in reply if ``WAKE_MAGICSECURE`` mode is supported. WOL_SET ======= Set or update wake-on-lan settings. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_WOL_HEADER`` nested request header ``ETHTOOL_A_WOL_MODES`` bitset enabled WoL modes ``ETHTOOL_A_WOL_SOPASS`` binary SecureOn(tm) password ==================================== ====== ========================== ``ETHTOOL_A_WOL_SOPASS`` is only allowed for devices supporting ``WAKE_MAGICSECURE`` mode. FEATURES_GET ============ Gets netdev features like ``ETHTOOL_GFEATURES`` ioctl request. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_FEATURES_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ==================================== ====== ========================== ``ETHTOOL_A_FEATURES_HEADER`` nested reply header ``ETHTOOL_A_FEATURES_HW`` bitset dev->hw_features ``ETHTOOL_A_FEATURES_WANTED`` bitset dev->wanted_features ``ETHTOOL_A_FEATURES_ACTIVE`` bitset dev->features ``ETHTOOL_A_FEATURES_NOCHANGE`` bitset NETIF_F_NEVER_CHANGE ==================================== ====== ========================== Bitmaps in kernel response have the same meaning as bitmaps used in ioctl interference but attribute names are different (they are based on corresponding members of struct net_device). Legacy "flags" are not provided, if userspace needs them (most likely only ethtool for backward compatibility), it can calculate their values from related feature bits itself. ETHA_FEATURES_HW uses mask consisting of all features recognized by kernel (to provide all names when using verbose bitmap format), the other three use no mask (simple bit lists). FEATURES_SET ============ Request to set netdev features like ``ETHTOOL_SFEATURES`` ioctl request. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_FEATURES_HEADER`` nested request header ``ETHTOOL_A_FEATURES_WANTED`` bitset requested features ==================================== ====== ========================== Kernel response contents: ==================================== ====== ========================== ``ETHTOOL_A_FEATURES_HEADER`` nested reply header ``ETHTOOL_A_FEATURES_WANTED`` bitset diff wanted vs. result ``ETHTOOL_A_FEATURES_ACTIVE`` bitset diff old vs. new active ==================================== ====== ========================== Request constains only one bitset which can be either value/mask pair (request to change specific feature bits and leave the rest) or only a value (request to set all features to specified set). As request is subject to netdev_change_features() sanity checks, optional kernel reply (can be suppressed by ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header) informs client about the actual result. ``ETHTOOL_A_FEATURES_WANTED`` reports the difference between client request and actual result: mask consists of bits which differ between requested features and result (dev->features after the operation), value consists of values of these bits in the request (i.e. negated values from resulting features). ``ETHTOOL_A_FEATURES_ACTIVE`` reports the difference between old and new dev->features: mask consists of bits which have changed, values are their values in new dev->features (after the operation). ``ETHTOOL_MSG_FEATURES_NTF`` notification is sent not only if device features are modified using ``ETHTOOL_MSG_FEATURES_SET`` request or on of ethtool ioctl request but also each time features are modified with netdev_update_features() or netdev_change_features(). PRIVFLAGS_GET ============= Gets private flags like ``ETHTOOL_GPFLAGS`` ioctl request. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_PRIVFLAGS_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ==================================== ====== ========================== ``ETHTOOL_A_PRIVFLAGS_HEADER`` nested reply header ``ETHTOOL_A_PRIVFLAGS_FLAGS`` bitset private flags ==================================== ====== ========================== ``ETHTOOL_A_PRIVFLAGS_FLAGS`` is a bitset with values of device private flags. These flags are defined by driver, their number and names (and also meaning) are device dependent. For compact bitset format, names can be retrieved as ``ETH_SS_PRIV_FLAGS`` string set. If verbose bitset format is requested, response uses all private flags supported by the device as mask so that client gets the full information without having to fetch the string set with names. PRIVFLAGS_SET ============= Sets or modifies values of device private flags like ``ETHTOOL_SPFLAGS`` ioctl request. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_PRIVFLAGS_HEADER`` nested request header ``ETHTOOL_A_PRIVFLAGS_FLAGS`` bitset private flags ==================================== ====== ========================== ``ETHTOOL_A_PRIVFLAGS_FLAGS`` can either set the whole set of private flags or modify only values of some of them. RINGS_GET ========= Gets ring sizes like ``ETHTOOL_GRINGPARAM`` ioctl request. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_RINGS_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ==================================== ====== ========================== ``ETHTOOL_A_RINGS_HEADER`` nested reply header ``ETHTOOL_A_RINGS_RX_MAX`` u32 max size of RX ring ``ETHTOOL_A_RINGS_RX_MINI_MAX`` u32 max size of RX mini ring ``ETHTOOL_A_RINGS_RX_JUMBO_MAX`` u32 max size of RX jumbo ring ``ETHTOOL_A_RINGS_TX_MAX`` u32 max size of TX ring ``ETHTOOL_A_RINGS_RX`` u32 size of RX ring ``ETHTOOL_A_RINGS_RX_MINI`` u32 size of RX mini ring ``ETHTOOL_A_RINGS_RX_JUMBO`` u32 size of RX jumbo ring ``ETHTOOL_A_RINGS_TX`` u32 size of TX ring ==================================== ====== ========================== RINGS_SET ========= Sets ring sizes like ``ETHTOOL_SRINGPARAM`` ioctl request.

Driver may impose additional constraints and may not suspport all attributes. CHANNELS_GET ============ Gets channel counts like ``ETHTOOL_GCHANNELS`` ioctl request. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_CHANNELS_HEADER`` nested request header ==================================== ====== ========================== Kernel response contents: ===================================== ====== ========================== ``ETHTOOL_A_CHANNELS_HEADER`` nested reply header ``ETHTOOL_A_CHANNELS_RX_MAX`` u32 max receive channels ``ETHTOOL_A_CHANNELS_TX_MAX`` u32 max transmit channels ``ETHTOOL_A_CHANNELS_OTHER_MAX`` u32 max other channels ``ETHTOOL_A_CHANNELS_COMBINED_MAX`` u32 max combined channels ``ETHTOOL_A_CHANNELS_RX_COUNT`` u32 receive channel count ``ETHTOOL_A_CHANNELS_TX_COUNT`` u32 transmit channel count ``ETHTOOL_A_CHANNELS_OTHER_COUNT`` u32 other channel count ``ETHTOOL_A_CHANNELS_COMBINED_COUNT`` u32 combined channel count ===================================== ====== ========================== CHANNELS_SET ============ Sets channel counts like ``ETHTOOL_SCHANNELS`` ioctl request.

The bitset attributes are omitted if they would be empty (no bit set). CABLE_TEST ========== Start a cable test. Request contents: ==================================== ====== ========================== ``ETHTOOL_A_CABLE_TEST_HEADER`` nested request header ==================================== ====== ========================== Notification contents: An Ethernet cable typically contains 1, 2 or 4 pairs. The length of the pair can only be measured when there is a fault in the pair and hence a reflection. Information about the fault may not be available, depending on the specific hardware. Hence the contents of the notify message are mostly optional. The attributes can be repeated an arbitrary number of times, in an arbitrary order, for an arbitrary number of pairs. The example shows the notification sent when the test is completed for a T2 cable, i.e. two pairs. One pair is OK and hence has no length information. The second pair has a fault and does have length information. +---------------------------------------------+--------+---------------------+ | ``ETHTOOL_A_CABLE_TEST_HEADER`` | nested | reply header | +---------------------------------------------+--------+---------------------+ | ``ETHTOOL_A_CABLE_TEST_STATUS`` | u8 | completed | +---------------------------------------------+--------+---------------------+ | ``ETHTOOL_A_CABLE_TEST_NTF_NEST`` | nested | all the results | +-+-------------------------------------------+--------+---------------------+ | | ``ETHTOOL_A_CABLE_NEST_RESULT`` | nested | cable test result | +-+-+-----------------------------------------+--------+---------------------+ | | | ``ETHTOOL_A_CABLE_RESULTS_PAIR`` | u8 | pair number | +-+-+-----------------------------------------+--------+---------------------+ | | | ``ETHTOOL_A_CABLE_RESULTS_CODE`` | u8 | result code | +-+-+-----------------------------------------+--------+---------------------+ | | ``ETHTOOL_A_CABLE_NEST_RESULT`` | nested | cable test results | +-+-+-----------------------------------------+--------+---------------------+ | | | ``ETHTOOL_A_CABLE_RESULTS_PAIR`` | u8 | pair number | +-+-+-----------------------------------------+--------+---------------------+ | | | ``ETHTOOL_A_CABLE_RESULTS_CODE`` | u8 | result code | +-+-+-----------------------------------------+--------+---------------------+ | | ``ETHTOOL_A_CABLE_NEST_FAULT_LENGTH`` | nested | cable length | +-+-+-----------------------------------------+--------+---------------------+ | | | ``ETHTOOL_A_CABLE_FAULT_LENGTH_PAIR`` | u8 | pair number | +-+-+-----------------------------------------+--------+---------------------+ | | | ``ETHTOOL_A_CABLE_FAULT_LENGTH_CM`` | u32 | length in cm | +-+-+-----------------------------------------+--------+---------------------+ CABLE_TEST TDR ============== Start a cable test and report raw TDR data Request contents: +--------------------------------------------+--------+-----------------------+ | ``ETHTOOL_A_CABLE_TEST_TDR_HEADER`` | nested | reply header | +--------------------------------------------+--------+-----------------------+ | ``ETHTOOL_A_CABLE_TEST_TDR_CFG`` | nested | test configuration | +-+------------------------------------------+--------+-----------------------+ | | ``ETHTOOL_A_CABLE_STEP_FIRST_DISTANCE`` | u32 | first data distance | +-+-+----------------------------------------+--------+-----------------------+ | | ``ETHTOOL_A_CABLE_STEP_LAST_DISTANCE`` | u32 | last data distance | +-+-+----------------------------------------+--------+-----------------------+ | | ``ETHTOOL_A_CABLE_STEP_STEP_DISTANCE`` | u32 | distance of each step | +-+-+----------------------------------------+--------+-----------------------+ | | ``ETHTOOL_A_CABLE_TEST_TDR_CFG_PAIR`` | u8 | pair to test | +-+-+----------------------------------------+--------+-----------------------+ The ETHTOOL_A_CABLE_TEST_TDR_CFG is optional, as well as all members of the nest. All distances are expressed in centimeters. The PHY takes the distances as a guide, and rounds to the nearest distance it actually supports. If a pair is passed, only that one pair will be tested. Otherwise all pairs are tested. Notification contents: Raw TDR data is gathered by sending a pulse down the cable and recording the amplitude of the reflected pulse for a given distance. It can take a number of seconds to collect TDR data, especial if the full 100 meters is probed at 1 meter intervals. When the test is started a notification will be sent containing just ETHTOOL_A_CABLE_TEST_TDR_STATUS with the value ETHTOOL_A_CABLE_TEST_NTF_STATUS_STARTED. When the test has completed a second notification will be sent containing ETHTOOL_A_CABLE_TEST_TDR_STATUS with the value ETHTOOL_A_CABLE_TEST_NTF_STATUS_COMPLETED and the TDR data. The message may optionally contain the amplitude of the pulse send down the cable. This is measured in mV. A reflection should not be bigger than transmitted pulse. Before the raw TDR data should be an ETHTOOL_A_CABLE_TDR_NEST_STEP nest containing information about the distance along the cable for the first reading, the last reading, and the step between each reading. Distances are measured in centimeters. These should be the exact values the PHY used. These may be different to what the user requested, if the native measurement resolution is greater than 1 cm. For each step along the cable, a ETHTOOL_A_CABLE_TDR_NEST_AMPLITUDE is used to report the amplitude of the reflection for a given pair. +---------------------------------------------+--------+----------------------+ | ``ETHTOOL_A_CABLE_TEST_TDR_HEADER`` | nested | reply header | +---------------------------------------------+--------+----------------------+ | ``ETHTOOL_A_CABLE_TEST_TDR_STATUS`` | u8 | completed | +---------------------------------------------+--------+----------------------+ | ``ETHTOOL_A_CABLE_TEST_TDR_NTF_NEST`` | nested | all the results | +-+-------------------------------------------+--------+----------------------+ | | ``ETHTOOL_A_CABLE_TDR_NEST_PULSE`` | nested | TX Pulse amplitude | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_PULSE_mV`` | s16 | Pulse amplitude | +-+-+-----------------------------------------+--------+----------------------+ | | ``ETHTOOL_A_CABLE_NEST_STEP`` | nested | TDR step info | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_STEP_FIRST_DISTANCE`` | u32 | First data distance | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_STEP_LAST_DISTANCE`` | u32 | Last data distance | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_STEP_STEP_DISTANCE`` | u32 | distance of each step| +-+-+-----------------------------------------+--------+----------------------+ | | ``ETHTOOL_A_CABLE_TDR_NEST_AMPLITUDE`` | nested | Reflection amplitude | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_RESULTS_PAIR`` | u8 | pair number | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_AMPLITUDE_mV`` | s16 | Reflection amplitude | +-+-+-----------------------------------------+--------+----------------------+ | | ``ETHTOOL_A_CABLE_TDR_NEST_AMPLITUDE`` | nested | Reflection amplitude | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_RESULTS_PAIR`` | u8 | pair number | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_AMPLITUDE_mV`` | s16 | Reflection amplitude | +-+-+-----------------------------------------+--------+----------------------+ | | ``ETHTOOL_A_CABLE_TDR_NEST_AMPLITUDE`` | nested | Reflection amplitude | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_RESULTS_PAIR`` | u8 | pair number | +-+-+-----------------------------------------+--------+----------------------+ | | | ``ETHTOOL_A_CABLE_AMPLITUDE_mV`` | s16 | Reflection amplitude | +-+-+-----------------------------------------+--------+----------------------+ TUNNEL_INFO =========== Gets information about the tunnel state NIC is aware of.

FEC_GET ======= Gets FEC configuration and state like ``ETHTOOL_GFECPARAM`` ioctl request. Request contents: ===================================== ====== ========================== ``ETHTOOL_A_FEC_HEADER`` nested request header ===================================== ====== ========================== Kernel response contents: ===================================== ====== ========================== ``ETHTOOL_A_FEC_HEADER`` nested request header ``ETHTOOL_A_FEC_MODES`` bitset configured modes ``ETHTOOL_A_FEC_AUTO`` bool FEC mode auto selection ``ETHTOOL_A_FEC_ACTIVE`` u32 index of active FEC mode ``ETHTOOL_A_FEC_STATS`` nested FEC statistics ===================================== ====== ========================== ``ETHTOOL_A_FEC_ACTIVE`` is the bit index of the FEC link mode currently active on the interface. This attribute may not be present if device does not support FEC. ``ETHTOOL_A_FEC_MODES`` and ``ETHTOOL_A_FEC_AUTO`` are only meaningful when autonegotiation is disabled. If ``ETHTOOL_A_FEC_AUTO`` is non-zero driver will select the FEC mode automatically based on the parameters of the SFP module. This is equivalent to the ``ETHTOOL_FEC_AUTO`` bit of the ioctl interface. ``ETHTOOL_A_FEC_MODES`` carry the current FEC configuration using link mode bits (rather than old ``ETHTOOL_FEC_*`` bits). ``ETHTOOL_A_FEC_STATS`` are reported if ``ETHTOOL_FLAG_STATS`` was set in ``ETHTOOL_A_HEADER_FLAGS``. Each attribute carries an array of 64bit statistics. First entry in the array contains the total number of events on the port, while the following entries are counters corresponding to lanes/PCS instances. The number of entries in the array will be: +--------------+---------------------------------------------+ | `0` | device does not support FEC statistics | +--------------+---------------------------------------------+ | `1` | device does not support per-lane break down | +--------------+---------------------------------------------+ | `1 + #lanes` | device has full support for FEC stats | +--------------+---------------------------------------------+ Drivers fill in the statistics in the following structure: .. kernel-doc:: include/linux/ethtool.h :identifiers: ethtool_fec_stats FEC_SET ======= Sets FEC parameters like ``ETHTOOL_SFECPARAM`` ioctl request. Request contents: ===================================== ====== ========================== ``ETHTOOL_A_FEC_HEADER`` nested request header ``ETHTOOL_A_FEC_MODES`` bitset configured modes ``ETHTOOL_A_FEC_AUTO`` bool FEC mode auto selection ===================================== ====== ========================== ``FEC_SET`` is only meaningful when autonegotiation is disabled. Otherwise FEC mode is selected as part of autonegotiation. ``ETHTOOL_A_FEC_MODES`` selects which FEC mode should be used. It's recommended to set only one bit, if multiple bits are set driver may choose between them in an implementation specific way. ``ETHTOOL_A_FEC_AUTO`` requests the driver to choose FEC mode based on SFP module parameters. This does not mean autonegotiation. MODULE_EEPROM ============= Fetch module EEPROM data dump. This interface is designed to allow dumps of at most 1/2 page at once. This means only dumps of 128 (or less) bytes are allowed, without crossing half page boundary located at offset 128. For pages other than 0 only high 128 bytes are accessible. Request contents: ======================================= ====== ========================== ``ETHTOOL_A_MODULE_EEPROM_HEADER`` nested request header ``ETHTOOL_A_MODULE_EEPROM_OFFSET`` u32 offset within a page ``ETHTOOL_A_MODULE_EEPROM_LENGTH`` u32 amount of bytes to read ``ETHTOOL_A_MODULE_EEPROM_PAGE`` u8 page number ``ETHTOOL_A_MODULE_EEPROM_BANK`` u8 bank number ``ETHTOOL_A_MODULE_EEPROM_I2C_ADDRESS`` u8 page I2C address ======================================= ====== ========================== Kernel response contents: +---------------------------------------------+--------+---------------------+ | ``ETHTOOL_A_MODULE_EEPROM_HEADER`` | nested | reply header | +---------------------------------------------+--------+---------------------+ | ``ETHTOOL_A_MODULE_EEPROM_DATA`` | nested | array of bytes from | | | | module EEPROM | +---------------------------------------------+--------+---------------------+ ``ETHTOOL_A_MODULE_EEPROM_DATA`` has an attribute length equal to the amount of bytes driver actually read.

Statistics are added to the ``ETHTOOL_A_STATS_GRP`` nest under ``ETHTOOL_A_STATS_GRP_STAT``. ``ETHTOOL_A_STATS_GRP_STAT`` should contain single 8 byte (u64) attribute inside - the type of that attribute is the statistic ID and the value is the value of the statistic. Each group has its own interpretation of statistic IDs. Attribute IDs correspond to strings from the string set identified by ``ETHTOOL_A_STATS_GRP_SS_ID``. Complex statistics (such as RMON histogram entries) are also listed inside ``ETHTOOL_A_STATS_GRP`` and do not have a string defined in the string set. RMON "histogram" counters count number of packets within given size range. Because RFC does not specify the ranges beyond the standard 1518 MTU devices differ in definition of buckets. For this reason the definition of packet ranges is left to each driver. ``ETHTOOL_A_STATS_GRP_HIST_RX`` and ``ETHTOOL_A_STATS_GRP_HIST_TX`` nests contain the following attributes: ================================= ====== =================================== ETHTOOL_A_STATS_RMON_HIST_BKT_LOW u32 low bound of the packet size bucket ETHTOOL_A_STATS_RMON_HIST_BKT_HI u32 high bound of the bucket ETHTOOL_A_STATS_RMON_HIST_VAL u64 packet counter ================================= ====== =================================== Low and high bounds are inclusive, for example: ============================= ==== ==== RFC statistic low high ============================= ==== ==== etherStatsPkts64Octets 0 64 etherStatsPkts512to1023Octets 512 1023 ============================= ==== ==== Request translation =================== The following table maps ioctl commands to netlink commands providing their functionality.
