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

253 ======================================== =================================
255 ``GET`` requests are sent by userspace applications to retrieve device
256 information. They usually do not contain any message specific attributes.
257 Kernel replies with corresponding "GET_REPLY" message. For most types, ``GET``
258 request with ``NLM_F_DUMP`` and no device identification can be used to query
259 the information for all devices supporting the request.
261 If the data can be also modified, corresponding ``SET`` message with the same
262 layout as corresponding ``GET_REPLY`` is used to request changes. Only
263 attributes where a change is requested are included in such request (also, not
264 all attributes may be changed). Replies to most ``SET`` request consist only
265 of error code and extack; if kernel provides additional data, it is sent in
266 the form of corresponding ``SET_REPLY`` message which can be suppressed by
267 setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header.
269 Data modification also triggers sending a ``NTF`` message with a notification.
270 These usually bear only a subset of attributes which was affected by the
271 change. The same notification is issued if the data is modified using other
272 means (mostly ioctl ethtool interface). Unlike notifications from ethtool
273 netlink code which are only sent if something actually changed, notifications
274 triggered by ioctl interface may be sent even if the request did not actually
277 ``ACT`` messages request kernel (driver) to perform a specific action. If some
278 information is reported by kernel (which can be suppressed by setting
279 ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header), the reply takes form of
280 an ``ACT_REPLY`` message. Performing an action also triggers a notification
283 Later sections describe the format and semantics of these messages.
289 Requests contents of a string set as provided by ioctl commands
290 ``ETHTOOL_GSSET_INFO`` and ``ETHTOOL_GSTRINGS.`` String sets are not user
291 writeable so that the corresponding ``STRSET_SET`` message is only used in
292 kernel replies. There are two types of string sets: global (independent of
293 a device, e.g. device feature names) and device specific (e.g. device private

332 Device identification in request header is optional. Depending on its presence
333 a and ``NLM_F_DUMP`` flag, there are three type of ``STRSET_GET`` requests:
335 - no ``NLM_F_DUMP,`` no device: get "global" stringsets
336 - no ``NLM_F_DUMP``, with device: get string sets related to the device
337 - ``NLM_F_DUMP``, no device: get device related string sets for all devices
339 If there is no ``ETHTOOL_A_STRSET_STRINGSETS`` array, all string sets of
340 requested type are returned, otherwise only those specified in the request.
341 Flag ``ETHTOOL_A_STRSET_COUNTS_ONLY`` tells kernel to only return string
342 counts of the sets, not the actual strings.

625 The message mask (``ETHTOOL_A_DEBUG_MSGMASK``) is equal to message level as
626 provided by ``ETHTOOL_GMSGLVL`` and set by ``ETHTOOL_SMSGLVL`` in ioctl
627 interface. While it is called message level there for historical reasons, most
628 drivers and almost all newer drivers use it as a mask of enabled message
629 classes (represented by ``NETIF_MSG_*`` constants); therefore netlink
630 interface follows its actual use in practice.

717 Bitmaps in kernel response have the same meaning as bitmaps used in ioctl
718 interference but attribute names are different (they are based on
719 corresponding members of struct net_device). Legacy "flags" are not provided,
720 if userspace needs them (most likely only ethtool for backward compatibility),
721 it can calculate their values from related feature bits itself.
722 ETHA_FEATURES_HW uses mask consisting of all features recognized by kernel (to
723 provide all names when using verbose bitmap format), the other three use no

747 Request constains only one bitset which can be either value/mask pair (request
748 to change specific feature bits and leave the rest) or only a value (request
749 to set all features to specified set).
751 As request is subject to netdev_change_features() sanity checks, optional
752 kernel reply (can be suppressed by ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request
753 header) informs client about the actual result. ``ETHTOOL_A_FEATURES_WANTED``
754 reports the difference between client request and actual result: mask consists
755 of bits which differ between requested features and result (dev->features
756 after the operation), value consists of values of these bits in the request
757 (i.e. negated values from resulting features). ``ETHTOOL_A_FEATURES_ACTIVE``
758 reports the difference between old and new dev->features: mask consists of
759 bits which have changed, values are their values in new dev->features (after
762 ``ETHTOOL_MSG_FEATURES_NTF`` notification is sent not only if device features
763 are modified using ``ETHTOOL_MSG_FEATURES_SET`` request or on of ethtool ioctl

786 ``ETHTOOL_A_PRIVFLAGS_FLAGS`` is a bitset with values of device private flags.
787 These flags are defined by driver, their number and names (and also meaning)
788 are device dependent. For compact bitset format, names can be retrieved as
789 ``ETH_SS_PRIV_FLAGS`` string set. If verbose bitset format is requested,
790 response uses all private flags supported by the device as mask so that client
791 gets the full information without having to fetch the string set with names.

1182 The ETHTOOL_A_CABLE_TEST_TDR_CFG is optional, as well as all members
1183 of the nest. All distances are expressed in centimeters. The PHY takes
1184 the distances as a guide, and rounds to the nearest distance it
1185 actually supports. If a pair is passed, only that one pair will be
1186 tested. Otherwise all pairs are tested.
1188 Notification contents:
1190 Raw TDR data is gathered by sending a pulse down the cable and
1191 recording the amplitude of the reflected pulse for a given distance.
1193 It can take a number of seconds to collect TDR data, especial if the
1194 full 100 meters is probed at 1 meter intervals. When the test is
1195 started a notification will be sent containing just
1196 ETHTOOL_A_CABLE_TEST_TDR_STATUS with the value
1197 ETHTOOL_A_CABLE_TEST_NTF_STATUS_STARTED.
1199 When the test has completed a second notification will be sent
1200 containing ETHTOOL_A_CABLE_TEST_TDR_STATUS with the value
1201 ETHTOOL_A_CABLE_TEST_NTF_STATUS_COMPLETED and the TDR data.
1203 The message may optionally contain the amplitude of the pulse send
1204 down the cable. This is measured in mV. A reflection should not be
1205 bigger than transmitted pulse.
1207 Before the raw TDR data should be an ETHTOOL_A_CABLE_TDR_NEST_STEP
1208 nest containing information about the distance along the cable for the
1209 first reading, the last reading, and the step between each
1210 reading. Distances are measured in centimeters. These should be the
1211 exact values the PHY used. These may be different to what the user
1212 requested, if the native measurement resolution is greater than 1 cm.
1214 For each step along the cable, a ETHTOOL_A_CABLE_TDR_NEST_AMPLITUDE is
1215 used to report the amplitude of the reflection for a given pair.

1312 ``ETHTOOL_A_FEC_ACTIVE`` is the bit index of the FEC link mode currently
1313 active on the interface. This attribute may not be present if device does
1316 ``ETHTOOL_A_FEC_MODES`` and ``ETHTOOL_A_FEC_AUTO`` are only meaningful when
1317 autonegotiation is disabled. If ``ETHTOOL_A_FEC_AUTO`` is non-zero driver will
1318 select the FEC mode automatically based on the parameters of the SFP module.
1319 This is equivalent to the ``ETHTOOL_FEC_AUTO`` bit of the ioctl interface.
1320 ``ETHTOOL_A_FEC_MODES`` carry the current FEC configuration using link mode
1321 bits (rather than old ``ETHTOOL_FEC_*`` bits).
1323 ``ETHTOOL_A_FEC_STATS`` are reported if ``ETHTOOL_FLAG_STATS`` was set in
1324 ``ETHTOOL_A_HEADER_FLAGS``.
1325 Each attribute carries an array of 64bit statistics. First entry in the array
1326 contains the total number of events on the port, while the following entries
1327 are counters corresponding to lanes/PCS instances. The number of entries in

1359 ``ETHTOOL_A_FEC_MODES`` selects which FEC mode should be used. It's recommended
1360 to set only one bit, if multiple bits are set driver may choose between them
1361 in an implementation specific way.

1435 ETHTOOL_STATS_ETH_PHY eth-phy Basic IEEE 802.3 PHY statistics (30.3.2.1.*)

1437 ETHTOOL_STATS_RMON rmon RMON (RFC 2819) statistics
1438 ====================== ======== ===============================================
1440 Each group should have a corresponding ``ETHTOOL_A_STATS_GRP`` in the reply.
1441 ``ETHTOOL_A_STATS_GRP_ID`` identifies which group's statistics nest contains.
1442 ``ETHTOOL_A_STATS_GRP_SS_ID`` identifies the string set ID for the names of
1443 the statistics in the group, if available.
1445 Statistics are added to the ``ETHTOOL_A_STATS_GRP`` nest under
1446 ``ETHTOOL_A_STATS_GRP_STAT``. ``ETHTOOL_A_STATS_GRP_STAT`` should contain
1447 single 8 byte (u64) attribute inside - the type of that attribute is
1448 the statistic ID and the value is the value of the statistic.
1449 Each group has its own interpretation of statistic IDs.
1450 Attribute IDs correspond to strings from the string set identified
1451 by ``ETHTOOL_A_STATS_GRP_SS_ID``. Complex statistics (such as RMON histogram
1452 entries) are also listed inside ``ETHTOOL_A_STATS_GRP`` and do not have
1453 a string defined in the string set.
1455 RMON "histogram" counters count number of packets within given size range.
1456 Because RFC does not specify the ranges beyond the standard 1518 MTU devices
1457 differ in definition of buckets. For this reason the definition of packet ranges
1458 is left to each driver.
1460 ``ETHTOOL_A_STATS_GRP_HIST_RX`` and ``ETHTOOL_A_STATS_GRP_HIST_TX`` nests
1461 contain the following attributes:
1463 ================================= ====== ===================================

1465 ETHTOOL_A_STATS_RMON_HIST_BKT_HI u32 high bound of the bucket
1466 ETHTOOL_A_STATS_RMON_HIST_VAL u64 packet counter
