1============================= 2Netlink interface for ethtool 3============================= 4 5 6Basic information 7================= 8 9Netlink interface for ethtool uses generic netlink family ``ethtool`` 10(userspace application should use macros ``ETHTOOL_GENL_NAME`` and 11``ETHTOOL_GENL_VERSION`` defined in ``<linux/ethtool_netlink.h>`` uapi 12header). This family does not use a specific header, all information in 13requests and replies is passed using netlink attributes. 14 15The ethtool netlink interface uses extended ACK for error and warning 16reporting, userspace application developers are encouraged to make these 17messages available to user in a suitable way. 18 19Requests can be divided into three categories: "get" (retrieving information), 20"set" (setting parameters) and "action" (invoking an action). 21 22All "set" and "action" type requests require admin privileges 23(``CAP_NET_ADMIN`` in the namespace). Most "get" type requests are allowed for 24anyone but there are exceptions (where the response contains sensitive 25information). In some cases, the request as such is allowed for anyone but 26unprivileged users have attributes with sensitive information (e.g. 27wake-on-lan password) omitted. 28 29 30Conventions 31=========== 32 33Attributes which represent a boolean value usually use NLA_U8 type so that we 34can distinguish three states: "on", "off" and "not present" (meaning the 35information is not available in "get" requests or value is not to be changed 36in "set" requests). For these attributes, the "true" value should be passed as 37number 1 but any non-zero value should be understood as "true" by recipient. 38In the tables below, "bool" denotes NLA_U8 attributes interpreted in this way. 39 40In the message structure descriptions below, if an attribute name is suffixed 41with "+", parent nest can contain multiple attributes of the same type. This 42implements an array of entries. 43 44Attributes that need to be filled-in by device drivers and that are dumped to 45user space based on whether they are valid or not should not use zero as a 46valid value. This avoids the need to explicitly signal the validity of the 47attribute in the device driver API. 48 49 50Request header 51============== 52 53Each request or reply message contains a nested attribute with common header. 54Structure of this header is 55 56 ============================== ====== ============================= 57 ``ETHTOOL_A_HEADER_DEV_INDEX`` u32 device ifindex 58 ``ETHTOOL_A_HEADER_DEV_NAME`` string device name 59 ``ETHTOOL_A_HEADER_FLAGS`` u32 flags common for all requests 60 ``ETHTOOL_A_HEADER_PHY_INDEX`` u32 phy device index 61 ============================== ====== ============================= 62 63``ETHTOOL_A_HEADER_DEV_INDEX`` and ``ETHTOOL_A_HEADER_DEV_NAME`` identify the 64device message relates to. One of them is sufficient in requests, if both are 65used, they must identify the same device. Some requests, e.g. global string 66sets, do not require device identification. Most ``GET`` requests also allow 67dump requests without device identification to query the same information for 68all devices providing it (each device in a separate message). 69 70``ETHTOOL_A_HEADER_FLAGS`` is a bitmap of request flags common for all request 71types. The interpretation of these flags is the same for all request types but 72the flags may not apply to requests. Recognized flags are: 73 74 ================================= =================================== 75 ``ETHTOOL_FLAG_COMPACT_BITSETS`` use compact format bitsets in reply 76 ``ETHTOOL_FLAG_OMIT_REPLY`` omit optional reply (_SET and _ACT) 77 ``ETHTOOL_FLAG_STATS`` include optional device statistics 78 ================================= =================================== 79 80New request flags should follow the general idea that if the flag is not set, 81the behaviour is backward compatible, i.e. requests from old clients not aware 82of the flag should be interpreted the way the client expects. A client must 83not set flags it does not understand. 84 85``ETHTOOL_A_HEADER_PHY_INDEX`` identifies the Ethernet PHY the message relates to. 86As there are numerous commands that are related to PHY configuration, and because 87there may be more than one PHY on the link, the PHY index can be passed in the 88request for the commands that needs it. It is, however, not mandatory, and if it 89is not passed for commands that target a PHY, the net_device.phydev pointer 90is used. 91 92Bit sets 93======== 94 95For short bitmaps of (reasonably) fixed length, standard ``NLA_BITFIELD32`` 96type is used. For arbitrary length bitmaps, ethtool netlink uses a nested 97attribute with contents of one of two forms: compact (two binary bitmaps 98representing bit values and mask of affected bits) and bit-by-bit (list of 99bits identified by either index or name). 100 101Verbose (bit-by-bit) bitsets allow sending symbolic names for bits together 102with their values which saves a round trip (when the bitset is passed in a 103request) or at least a second request (when the bitset is in a reply). This is 104useful for one shot applications like traditional ethtool command. On the 105other hand, long running applications like ethtool monitor (displaying 106notifications) or network management daemons may prefer fetching the names 107only once and using compact form to save message size. Notifications from 108ethtool netlink interface always use compact form for bitsets. 109 110A bitset can represent either a value/mask pair (``ETHTOOL_A_BITSET_NOMASK`` 111not set) or a single bitmap (``ETHTOOL_A_BITSET_NOMASK`` set). In requests 112modifying a bitmap, the former changes the bit set in mask to values set in 113value and preserves the rest; the latter sets the bits set in the bitmap and 114clears the rest. 115 116Compact form: nested (bitset) attribute contents: 117 118 ============================ ====== ============================ 119 ``ETHTOOL_A_BITSET_NOMASK`` flag no mask, only a list 120 ``ETHTOOL_A_BITSET_SIZE`` u32 number of significant bits 121 ``ETHTOOL_A_BITSET_VALUE`` binary bitmap of bit values 122 ``ETHTOOL_A_BITSET_MASK`` binary bitmap of valid bits 123 ============================ ====== ============================ 124 125Value and mask must have length at least ``ETHTOOL_A_BITSET_SIZE`` bits 126rounded up to a multiple of 32 bits. They consist of 32-bit words in host byte 127order, words ordered from least significant to most significant (i.e. the same 128way as bitmaps are passed with ioctl interface). 129 130For compact form, ``ETHTOOL_A_BITSET_SIZE`` and ``ETHTOOL_A_BITSET_VALUE`` are 131mandatory. ``ETHTOOL_A_BITSET_MASK`` attribute is mandatory if 132``ETHTOOL_A_BITSET_NOMASK`` is not set (bitset represents a value/mask pair); 133if ``ETHTOOL_A_BITSET_NOMASK`` is not set, ``ETHTOOL_A_BITSET_MASK`` is not 134allowed (bitset represents a single bitmap. 135 136Kernel bit set length may differ from userspace length if older application is 137used on newer kernel or vice versa. If userspace bitmap is longer, an error is 138issued only if the request actually tries to set values of some bits not 139recognized by kernel. 140 141Bit-by-bit form: nested (bitset) attribute contents: 142 143 +------------------------------------+--------+-----------------------------+ 144 | ``ETHTOOL_A_BITSET_NOMASK`` | flag | no mask, only a list | 145 +------------------------------------+--------+-----------------------------+ 146 | ``ETHTOOL_A_BITSET_SIZE`` | u32 | number of significant bits | 147 +------------------------------------+--------+-----------------------------+ 148 | ``ETHTOOL_A_BITSET_BITS`` | nested | array of bits | 149 +-+----------------------------------+--------+-----------------------------+ 150 | | ``ETHTOOL_A_BITSET_BITS_BIT+`` | nested | one bit | 151 +-+-+--------------------------------+--------+-----------------------------+ 152 | | | ``ETHTOOL_A_BITSET_BIT_INDEX`` | u32 | bit index (0 for LSB) | 153 +-+-+--------------------------------+--------+-----------------------------+ 154 | | | ``ETHTOOL_A_BITSET_BIT_NAME`` | string | bit name | 155 +-+-+--------------------------------+--------+-----------------------------+ 156 | | | ``ETHTOOL_A_BITSET_BIT_VALUE`` | flag | present if bit is set | 157 +-+-+--------------------------------+--------+-----------------------------+ 158 159Bit size is optional for bit-by-bit form. ``ETHTOOL_A_BITSET_BITS`` nest can 160only contain ``ETHTOOL_A_BITSET_BITS_BIT`` attributes but there can be an 161arbitrary number of them. A bit may be identified by its index or by its 162name. When used in requests, listed bits are set to 0 or 1 according to 163``ETHTOOL_A_BITSET_BIT_VALUE``, the rest is preserved. A request fails if 164index exceeds kernel bit length or if name is not recognized. 165 166When ``ETHTOOL_A_BITSET_NOMASK`` flag is present, bitset is interpreted as 167a simple bitmap. ``ETHTOOL_A_BITSET_BIT_VALUE`` attributes are not used in 168such case. Such bitset represents a bitmap with listed bits set and the rest 169zero. 170 171In requests, application can use either form. Form used by kernel in reply is 172determined by ``ETHTOOL_FLAG_COMPACT_BITSETS`` flag in flags field of request 173header. Semantics of value and mask depends on the attribute. 174 175 176List of message types 177===================== 178 179All constants identifying message types use ``ETHTOOL_CMD_`` prefix and suffix

retrieve device 292information. They usually do not contain any message specific attributes. 293Kernel replies with corresponding "GET_REPLY" message. For most types, ``GET`` 294request with ``NLM_F_DUMP`` and no device identification can be used to query 295the information for all devices supporting the request. 296 297If the data can be also modified, corresponding ``SET`` message with the same 298layout as corresponding ``GET_REPLY`` is used to request changes. Only 299attributes where a change is requested are included in such request (also, not 300all attributes may be changed). Replies to most ``SET`` request consist only 301of error code and extack; if kernel provides additional data, it is sent in 302the form of corresponding ``SET_REPLY`` message which can be suppressed by 303setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header. 304 305Data modification also triggers sending a ``NTF`` message with a notification. 306These usually bear only a subset of attributes which was affected by the 307change. The same notification is issued if the data is modified using other 308means (mostly ioctl ethtool interface). Unlike notifications from ethtool 309netlink code which are only sent if something actually changed, notifications 310triggered by ioctl interface may be sent even if the request did not actually 311change any data. 312 313``ACT`` messages request kernel (driver) to perform a specific action. If some 314information is reported by kernel (which can be suppressed by setting 315``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header), the reply takes form of 316an ``ACT_REPLY`` message. Performing an action also triggers a notification 317(``NTF`` message). 318 319Later sections describe the format and semantics of these messages. 320 321 322STRSET_GET 323========== 324 325Requests contents of a string set as provided by ioctl commands 326``ETHTOOL_GSSET_INFO`` and ``ETHTOOL_GSTRINGS.`` String sets are not user 327writeable so that the corresponding ``STRSET_SET`` message is only used in 328kernel replies. There are two types of string sets: global (independent of 329a device, e.g. device feature names) and device specific (e.g. device private 330flags). 331 332Request contents: 333 334 +---------------------------------------+--------+------------------------+ 335 | ``ETHTOOL_A_STRSET_HEADER`` | nested | request header | 336 +---------------------------------------+--------+------------------------+ 337 | ``ETHTOOL_A_STRSET_STRINGSETS`` | nested | string set to request | 338 +-+-------------------------------------+--------+------------------------+ 339 | | ``ETHTOOL_A_STRINGSETS_STRINGSET+`` | nested | one string set | 340 +-+-+-----------------------------------+--------+------------------------+ 341 | | | ``ETHTOOL_A_STRINGSET_ID`` | u32 | set id | 342 +-+-+-----------------------------------+--------+------------------------+ 343 344Kernel response contents: 345 346 +---------------------------------------+--------+-----------------------+ 347 | ``ETHTOOL_A_STRSET_HEADER`` | nested | reply header | 348 +---------------------------------------+--------+-----------------------+ 349 | ``ETHTOOL_A_STRSET_STRINGSETS`` | nested | array of string sets | 350 +-+-------------------------------------+--------+-----------------------+ 351 | | ``ETHTOOL_A_STRINGSETS_STRINGSET+`` | nested | one string set | 352 +-+-+-----------------------------------+--------+-----------------------+ 353 | | | ``ETHTOOL_A_STRINGSET_ID`` | u32 | set id | 354 +-+-+-----------------------------------+--------+-----------------------+ 355 | | | ``ETHTOOL_A_STRINGSET_COUNT`` | u32 | number of strings | 356 +-+-+-----------------------------------+--------+-----------------------+ 357 | | | ``ETHTOOL_A_STRINGSET_STRINGS`` | nested | array of strings | 358 +-+-+-+---------------------------------+--------+-----------------------+ 359 | | | | ``ETHTOOL_A_STRINGS_STRING+`` | nested | one string | 360 +-+-+-+-+-------------------------------+--------+-----------------------+ 361 | | | | | ``ETHTOOL_A_STRING_INDEX`` | u32 | string index | 362 +-+-+-+-+-------------------------------+--------+-----------------------+ 363 | | | | | ``ETHTOOL_A_STRING_VALUE`` | string | string value | 364 +-+-+-+-+-------------------------------+--------+-----------------------+ 365 | ``ETHTOOL_A_STRSET_COUNTS_ONLY`` | flag | return only counts | 366 +---------------------------------------+--------+-----------------------+ 367 368Device identification in request header is optional. Depending on its presence 369a and ``NLM_F_DUMP`` flag, there are three type of ``STRSET_GET`` requests: 370 371 - no ``NLM_F_DUMP,`` no device: get "global" stringsets 372 - no ``NLM_F_DUMP``, with device: get string sets related to the device 373 - ``NLM_F_DUMP``, no device: get device related string sets for all devices 374 375If there is no ``ETHTOOL_A_STRSET_STRINGSETS`` array, all string sets of 376requested type are returned, otherwise only those specified in the request. 377Flag ``ETHTOOL_A_STRSET_COUNTS_ONLY`` tells kernel to only return string 378counts of the sets, not the actual strings. 379 380 381LINKINFO_GET 382============ 383 384Requests link settings as provided by ``ETHTOOL_GLINKSETTINGS`` except for 385link modes and autonegotiation related information.

The device configuration must make it possible to receive 904full memory pages of data, for example because MTU is high enough or through 905HW-GRO. 906 907``ETHTOOL_A_RINGS_[RX|TX]_PUSH`` flag is used to enable descriptor fast 908path to send or receive packets. In ordinary path, driver fills descriptors in DRAM and 909notifies NIC hardware. In fast path, driver pushes descriptors to the device 910through MMIO writes, thus reducing the latency. However, enabling this feature 911may increase the CPU cost. Drivers may enforce additional per-packet 912eligibility checks (e.g. on packet size). 913 914``ETHTOOL_A_RINGS_TX_PUSH_BUF_LEN`` specifies the maximum number of bytes of a 915transmitted packet a driver can push directly to the underlying device 916('push' mode). Pushing some of the payload bytes to the device has the 917advantages of reducing latency for small packets by avoiding DMA mapping (same 918as ``ETHTOOL_A_RINGS_TX_PUSH`` parameter) as well as allowing the underlying 919device to process packet headers ahead of fetching its payload. 920This can help the device to make fast actions based on the packet's headers. 921This is similar to the "tx-copybreak" parameter, which copies the packet to a 922preallocated DMA memory area instead of mapping new memory. However, 923tx-push-buff parameter copies the packet directly to the device to allow the 924device to take faster actions on the packet. 925 926RINGS_SET 927========= 928 929Sets ring sizes like ``ETHTOOL_SRINGPARAM`` ioctl request. 930 931Request contents: 932 933 ==================================== ====== =========================== 934 ``ETHTOOL_A_RINGS_HEADER`` nested reply header 935 ``ETHTOOL_A_RINGS_RX`` u32 size of RX ring 936 ``ETHTOOL_A_RINGS_RX_MINI`` u32 size of RX mini ring 937 ``ETHTOOL_A_RINGS_RX_JUMBO`` u32 size of RX jumbo ring 938 ``ETHTOOL_A_RINGS_TX`` u32 size of TX ring 939 ``ETHTOOL_A_RINGS_RX_BUF_LEN`` u32 size of buffers on the ring 940 ``ETHTOOL_A_RINGS_CQE_SIZE`` u32 Size of TX/RX CQE 941 ``ETHTOOL_A_RINGS_TX_PUSH`` u8 flag of TX Push mode 942 ``ETHTOOL_A_RINGS_RX_PUSH`` u8 flag of RX Push mode 943 ``ETHTOOL_A_RINGS_TX_PUSH_BUF_LEN`` u32 size of TX push buffer 944 ==================================== ====== =========================== 945 946Kernel checks that requested ring sizes do not exceed limits reported by 947driver.

The CQE size parameter 955enables to modify the CQE size other than default size if NIC supports it. 956A bigger CQE can have more receive buffer pointers, and in turn the NIC can 957transfer a bigger frame from wire. Based on the NIC hardware, the overall 958completion queue size can be adjusted in the driver if CQE size is modified. 959 960CHANNELS_GET 961============ 962 963Gets channel counts like ``ETHTOOL_GCHANNELS`` ioctl request. 964 965Request contents: 966 967 ==================================== ====== ========================== 968 ``ETHTOOL_A_CHANNELS_HEADER`` nested request header 969 ==================================== ====== ========================== 970 971Kernel response contents: 972 973 ===================================== ====== ========================== 974 ``ETHTOOL_A_CHANNELS_HEADER`` nested reply header 975 ``ETHTOOL_A_CHANNELS_RX_MAX`` u32 max receive channels 976 ``ETHTOOL_A_CHANNELS_TX_MAX`` u32 max transmit channels 977 ``ETHTOOL_A_CHANNELS_OTHER_MAX`` u32 max other channels 978 ``ETHTOOL_A_CHANNELS_COMBINED_MAX`` u32 max combined channels 979 ``ETHTOOL_A_CHANNELS_RX_COUNT`` u32 receive channel count 980 ``ETHTOOL_A_CHANNELS_TX_COUNT`` u32 transmit channel count 981 ``ETHTOOL_A_CHANNELS_OTHER_COUNT`` u32 other channel count 982 ``ETHTOOL_A_CHANNELS_COMBINED_COUNT`` u32 combined channel count 983 ===================================== ====== ========================== 984 985 986CHANNELS_SET 987============ 988 989Sets channel counts like ``ETHTOOL_SCHANNELS`` ioctl request. 990 991Request contents: 992 993 ===================================== ====== ========================== 994 ``ETHTOOL_A_CHANNELS_HEADER`` nested request header 995 ``ETHTOOL_A_CHANNELS_RX_COUNT`` u32 receive channel count 996 ``ETHTOOL_A_CHANNELS_TX_COUNT`` u32 transmit channel count 997 ``ETHTOOL_A_CHANNELS_OTHER_COUNT`` u32 other channel count 998 ``ETHTOOL_A_CHANNELS_COMBINED_COUNT`` u32 combined channel count 999 ===================================== ====== ========================== 1000 1001Kernel checks that requested channel counts do not exceed limits reported by 1002driver.

In this mode timer is used to force 1065the interrupt if queue goes idle, while busy queues depend on the packet 1066limit to trigger interrupts. 1067 1068Tx aggregation consists of copying frames into a contiguous buffer so that they 1069can be submitted as a single IO operation. ``ETHTOOL_A_COALESCE_TX_AGGR_MAX_BYTES`` 1070describes the maximum size in bytes for the submitted buffer. 1071``ETHTOOL_A_COALESCE_TX_AGGR_MAX_FRAMES`` describes the maximum number of frames 1072that can be aggregated into a single buffer. 1073``ETHTOOL_A_COALESCE_TX_AGGR_TIME_USECS`` describes the amount of time in usecs, 1074counted since the first packet arrival in an aggregated block, after which the 1075block should be sent. 1076This feature is mainly of interest for specific USB devices which does not cope 1077well with frequent small-sized URBs transmissions. 1078 1079``ETHTOOL_A_COALESCE_RX_PROFILE`` and ``ETHTOOL_A_COALESCE_TX_PROFILE`` refer 1080to DIM parameters, see `Generic Network Dynamic Interrupt Moderation (Net DIM) 1081<https://www.kernel.org/doc/Documentation/networking/net_dim.rst>`_. 1082 1083COALESCE_SET 1084============ 1085 1086Sets coalescing parameters like ``ETHTOOL_SCOALESCE`` ioctl request. 1087 1088Request contents: 1089 1090 =========================================== ====== ======================= 1091 ``ETHTOOL_A_COALESCE_HEADER`` nested request header 1092 ``ETHTOOL_A_COALESCE_RX_USECS`` u32 delay (us), normal Rx 1093 ``ETHTOOL_A_COALESCE_RX_MAX_FRAMES`` u32 max packets, normal Rx 1094 ``ETHTOOL_A_COALESCE_RX_USECS_IRQ`` u32 delay (us), Rx in IRQ 1095 ``ETHTOOL_A_COALESCE_RX_MAX_FRAMES_IRQ`` u32 max packets, Rx in IRQ 1096 ``ETHTOOL_A_COALESCE_TX_USECS`` u32 delay (us), normal Tx 1097 ``ETHTOOL_A_COALESCE_TX_MAX_FRAMES`` u32 max packets, normal Tx 1098 ``ETHTOOL_A_COALESCE_TX_USECS_IRQ`` u32 delay (us), Tx in IRQ 1099 ``ETHTOOL_A_COALESCE_TX_MAX_FRAMES_IRQ`` u32 IRQ packets, Tx in IRQ 1100 ``ETHTOOL_A_COALESCE_STATS_BLOCK_USECS`` u32 delay of stats update 1101 ``ETHTOOL_A_COALESCE_USE_ADAPTIVE_RX`` bool adaptive Rx coalesce 1102 ``ETHTOOL_A_COALESCE_USE_ADAPTIVE_TX`` bool adaptive Tx coalesce 1103 ``ETHTOOL_A_COALESCE_PKT_RATE_LOW`` u32 threshold for low rate 1104 ``ETHTOOL_A_COALESCE_RX_USECS_LOW`` u32 delay (us), low Rx 1105 ``ETHTOOL_A_COALESCE_RX_MAX_FRAMES_LOW`` u32 max packets, low Rx 1106 ``ETHTOOL_A_COALESCE_TX_USECS_LOW`` u32 delay (us), low Tx 1107 ``ETHTOOL_A_COALESCE_TX_MAX_FRAMES_LOW`` u32 max packets, low Tx 1108 ``ETHTOOL_A_COALESCE_PKT_RATE_HIGH`` u32 threshold for high rate 1109 ``ETHTOOL_A_COALESCE_RX_USECS_HIGH`` u32 delay (us), high Rx 1110 ``ETHTOOL_A_COALESCE_RX_MAX_FRAMES_HIGH`` u32 max packets, high Rx 1111 ``ETHTOOL_A_COALESCE_TX_USECS_HIGH`` u32 delay (us), high Tx 1112 ``ETHTOOL_A_COALESCE_TX_MAX_FRAMES_HIGH`` u32 max packets, high Tx 1113 ``ETHTOOL_A_COALESCE_RATE_SAMPLE_INTERVAL`` u32 rate sampling interval 1114 ``ETHTOOL_A_COALESCE_USE_CQE_TX`` bool timer reset mode, Tx 1115 ``ETHTOOL_A_COALESCE_USE_CQE_RX`` bool timer reset mode, Rx 1116 ``ETHTOOL_A_COALESCE_TX_AGGR_MAX_BYTES`` u32 max aggr size, Tx 1117 ``ETHTOOL_A_COALESCE_TX_AGGR_MAX_FRAMES`` u32 max aggr packets, Tx 1118 ``ETHTOOL_A_COALESCE_TX_AGGR_TIME_USECS`` u32 time (us), aggr, Tx 1119 ``ETHTOOL_A_COALESCE_RX_PROFILE`` nested profile of DIM, Rx 1120 ``ETHTOOL_A_COALESCE_TX_PROFILE`` nested profile of DIM, Tx 1121 =========================================== ====== ======================= 1122 1123Request is rejected if it attributes declared as unsupported by driver (i.e. 1124such that the corresponding bit in ``ethtool_ops::supported_coalesce_params`` 1125is not set), regardless of their values.

Downloading a firmware image to the transceiver module and validating it. 21522. Running the firmware image. 21533. Committing the firmware image so that it is run upon reset. 2154 2155When flash command is given, those three steps are taken in that order. 2156 2157This message merely schedules the update process and returns immediately 2158without blocking. The process then runs asynchronously. 2159Since it can take several minutes to complete, during the update process 2160notifications are emitted from the kernel to user space updating it about 2161the status and progress. 2162 2163The ``ETHTOOL_A_MODULE_FW_FLASH_FILE_NAME`` attribute encodes the firmware 2164image file name. The firmware image is downloaded to the transceiver module, 2165validated, run and committed. 2166 2167The optional ``ETHTOOL_A_MODULE_FW_FLASH_PASSWORD`` attribute encodes a password 2168that might be required as part of the transceiver module firmware update 2169process. 2170 2171The firmware update process can take several minutes to complete.
