 273 * @get_regs: Get device registers
 274 * @get_wol: Report whether Wake-on-Lan is enabled
 275 * @set_wol: Turn Wake-on-Lan on or off.  Returns a negative error code

 278 *      of the @msg_enable field used by netif logging functions.

 280 * @nway_reset: Restart autonegotiation.  Returns a negative error code

 282 * @get_link: Report whether physical link is up.  Will only be called if
 283 *      the netdev is up.  Should usually be set to ethtool_op_get_link(),
 284 *      which uses netif_carrier_ok().
 285 * @get_link_ext_state: Report link extended state. Should set link_ext_state and
 286 *      link_ext_substate (link_ext_substate of 0 means link_ext_substate is unknown,
 287 *      do not attach ext_substate attribute to netlink message). If link_ext_state

 299 * @get_coalesce: Get interrupt coalescing parameters.  Returns a negative

 301 * @set_coalesce: Set interrupt coalescing parameters.  Supported coalescing

 304 * @get_ringparam: Report ring sizes
 305 * @set_ringparam: Set ring sizes.  Returns a negative error code or zero.
 306 * @get_pause_stats: Report pause frame statistics. Drivers must not zero
 307 *      statistics which they don't report. The stats structure is initialized
 308 *      to ETHTOOL_STAT_NOT_SET indicating driver does not report statistics.
 309 * @get_pauseparam: Report pause parameters
 310 * @set_pauseparam: Set pause parameters.  Returns a negative error code
 311 *      or zero.
 312 * @self_test: Run specified self-tests
 313 * @get_strings: Return a set of strings that describe the requested objects
 314 * @set_phys_id: Identify the physical devices, e.g. by flashing an LED
 315 *      attached to it.  The implementation may update the indicator
 316 *      asynchronously or synchronously, but in either case it must return
 317 *      quickly.  It is initially called with the argument %ETHTOOL_ID_ACTIVE,
 318 *      and must either activate asynchronous updates and return zero, return
 319 *      a negative error or return a positive frequency for synchronous
 320 *      indication (e.g. 1 for one on/off cycle per second).  If it returns
 321 *      a frequency then it will be called again at intervals with the
 322 *      argument %ETHTOOL_ID_ON or %ETHTOOL_ID_OFF and should set the state of
 323 *      the indicator accordingly.  Finally, it is called with the argument
 324 *      %ETHTOOL_ID_INACTIVE and must deactivate the indicator.  Returns a
 325 *      negative error code or zero.
 326 * @get_ethtool_stats: Return extended statistics about the device.
 327 *      This is only useful if the device maintains statistics not
 328 *      included in &struct rtnl_link_stats64.
 329 * @begin: Function to be called before any other operation.  Returns a
 330 *      negative error code or zero.
 331 * @complete: Function to be called after any other operation except
 332 *      @begin.  Will be called even if the other operation failed.
 333 * @get_priv_flags: Report driver-specific feature flags.
 334 * @set_priv_flags: Set driver-specific feature flags.  Returns a negative

 336 * @get_sset_count: Get number of strings that @get_strings will write.
 337 * @get_rxnfc: Get RX flow classification rules.  Returns a negative
 338 *      error code or zero.
 339 * @set_rxnfc: Set RX flow classification rules.  Returns a negative

 341 * @flash_device: Write a firmware image to device's flash memory.
 342 *      Returns a negative error code or zero.
 343 * @reset: Reset (part of) the device, as specified by a bitmask of
 344 *      flags from &enum ethtool_reset_flags.  Returns a negative
 345 *      error code or zero.
 346 * @get_rxfh_key_size: Get the size of the RX flow hash key.
 347 *      Returns zero if not supported for this specific device.
 348 * @get_rxfh_indir_size: Get the size of the RX flow hash indirection table.
 349 *      Returns zero if not supported for this specific device.

 352 *      Returns a negative error code or zero.
 353 * @set_rxfh: Set the contents of the RX flow hash indirection table, hash
 354 *      key, and/or hash function.  Arguments which are set to %NULL or zero
 355 *      will remain unchanged.
 356 *      Returns a negative error code or zero. An error code must be returned
 357 *      if at least one unsupported change was requested.
 358 * @get_rxfh_context: Get the contents of the RX flow hash indirection table,
 359 *      hash key, and/or hash function assiciated to the given rss context.
 360 *      Returns a negative error code or zero.
 361 * @set_rxfh_context: Create, remove and configure RSS contexts. Allows setting
 362 *      the contents of the RX flow hash indirection table, hash key, and/or
 363 *      hash function associated to the given context. Arguments which are set
 364 *      to %NULL or zero will remain unchanged.
 365 *      Returns a negative error code or zero. An error code must be returned
 366 *      if at least one unsupported change was requested.
 367 * @get_channels: Get number of channels.
 368 * @set_channels: Set number of channels.  Returns a negative error code or
 369 *      zero.
 370 * @get_dump_flag: Get dump flag indicating current dump length, version,
 371 *                 and flag of the device.
 372 * @get_dump_data: Get dump data.
 373 * @set_dump: Set dump specific flags to the device.
 374 * @get_ts_info: Get the time stamping and PTP hardware clock capabilities.
 375 *      Drivers supporting transmit time stamps in software should set this to
 376 *      ethtool_op_get_ts_info().
 377 * @get_module_info: Get the size and type of the eeprom contained within
 378 *      a plug-in module.
 379 * @get_module_eeprom: Get the eeprom information from the plug-in module
 380 * @get_eee: Get Energy-Efficient (EEE) supported and status.
 381 * @set_eee: Set EEE status (enable/disable) as well as LPI timers.
 382 * @get_per_queue_coalesce: Get interrupt coalescing parameters per queue.
 383 *      It must check that the given queue number is valid. If neither a RX nor
 384 *      a TX queue has this number, return -EINVAL. If only a RX queue or a TX
 385 *      queue has this number, set the inapplicable fields to ~0 and return 0.
 386 *      Returns a negative error code or zero.
 387 * @set_per_queue_coalesce: Set interrupt coalescing parameters per queue.
 388 *      It must check that the given queue number is valid. If neither a RX nor
 389 *      a TX queue has this number, return -EINVAL. If only a RX queue or a TX
 390 *      queue has this number, ignore the inapplicable fields. Supported
 391 *      coalescing types should be set in @supported_coalesce_params.
 392 *      Returns a negative error code or zero.
 393 * @get_link_ksettings: Get various device settings including Ethernet link
 394 *      settings. The %cmd and %link_mode_masks_nwords fields should be
 395 *      ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter),
 396 *      any change to them will be overwritten by kernel. Returns a negative
 397 *      error code or zero.
 398 * @set_link_ksettings: Set various device settings including Ethernet link
 399 *      settings. The %cmd and %link_mode_masks_nwords fields should be
 400 *      ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter),
 401 *      any change to them will be overwritten by kernel. Returns a negative
 402 *      error code or zero.
 403 * @get_fecparam: Get the network device Forward Error Correction parameters.
 404 * @set_fecparam: Set the network device Forward Error Correction parameters.
 405 * @get_ethtool_phy_stats: Return extended statistics about the PHY device.
 406 *      This is only useful if the device maintains PHY statistics and
 407 *      cannot use the standard PHY library helpers.
 408 *
 409 * All operations are optional (i.e. the function pointer may be set
 410 * to %NULL) and callers must take this into account.  Callers must
 411 * hold the RTNL lock.
 412 *
 413 * See the structures used by these operations for further documentation.
 414 * Note that for all operations using a structure ending with a zero-
 415 * length array, the array is allocated separately in the kernel and
 416 * is passed to the driver as an additional parameter.
 417 *
 418 * See &struct net_device and &struct net_device_ops for documentation
 419 * of the generic netdev features interface.
