 *	zero.
 * @set_settings: Set various device settings including Ethernet link
 *	settings.  Returns a negative error code or zero.
 * @get_drvinfo: Report driver/device information.  Should only set the
 *	@driver, @version, @fw_version and @bus_info fields.  If not
 *	implemented, the @driver and @bus_info fields will be filled in
 *	according to the netdev's parent device.
 * @get_regs_len: Get buffer length required for @get_regs
 * @get_regs: Get device registers
 * @get_wol: Report whether Wake-on-Lan is enabled
 * @set_wol: Turn Wake-on-Lan on or off.  Returns a negative error code
 *	or zero.

 *	of the @msg_enable field used by netif logging functions.
 * @set_msglevel: Set driver message level
 * @nway_reset: Restart autonegotiation.  Returns a negative error code
 *	or zero.
 * @get_link: Report whether physical link is up.  Will only be called if
 *	the netdev is up.  Should usually be set to ethtool_op_get_link(),
 *	which uses netif_carrier_ok().
 * @get_eeprom: Read data from the device EEPROM.
 *	Should fill in the magic field.  Don't need to check len for zero
 *	or wraparound.  Fill in the data argument with the eeprom values
 *	from offset to offset + len.  Update len to the amount read.
 *	Returns an error or zero.
 * @set_eeprom: Write data to the device EEPROM.
 *	Should validate the magic field.  Don't need to check len for zero
 *	or wraparound.  Update len to the amount written.  Returns an error
 *	or zero.
 * @get_coalesce: Get interrupt coalescing parameters.  Returns a negative

 * @self_test: Run specified self-tests
 * @get_strings: Return a set of strings that describe the requested objects
 * @set_phys_id: Identify the physical devices, e.g. by flashing an LED
 *	attached to it.  The implementation may update the indicator
 *	asynchronously or synchronously, but in either case it must return
 *	quickly.  It is initially called with the argument %ETHTOOL_ID_ACTIVE,
 *	and must either activate asynchronous updates and return zero, return
 *	a negative error or return a positive frequency for synchronous
 *	indication (e.g. 1 for one on/off cycle per second).  If it returns
 *	a frequency then it will be called again at intervals with the
 *	argument %ETHTOOL_ID_ON or %ETHTOOL_ID_OFF and should set the state of
 *	the indicator accordingly.  Finally, it is called with the argument
 *	%ETHTOOL_ID_INACTIVE and must deactivate the indicator.  Returns a
 *	negative error code or zero.
 * @get_ethtool_stats: Return extended statistics about the device.
 *	This is only useful if the device maintains statistics not
 *	included in &struct rtnl_link_stats64.
 * @begin: Function to be called before any other operation.  Returns a
 *	negative error code or zero.
 * @complete: Function to be called after any other operation except
 *	@begin.  Will be called even if the other operation failed.
 * @get_priv_flags: Report driver-specific feature flags.

 *	error code or zero.
 * @get_sset_count: Get number of strings that @get_strings will write.

 *	error code or zero.

 *	flags from &enum ethtool_reset_flags.  Returns a negative
 *	error code or zero.
 * @get_rxfh_key_size: Get the size of the RX flow hash key.
 *	Returns zero if not supported for this specific device.
 * @get_rxfh_indir_size: Get the size of the RX flow hash indirection table.
 *	Returns zero if not supported for this specific device.
 * @get_rxfh: Get the contents of the RX flow hash indirection table, hash key
 *	and/or hash function.
 *	Returns a negative error code or zero.
 * @set_rxfh: Set the contents of the RX flow hash indirection table, hash
 *	key, and/or hash function.  Arguments which are set to %NULL or zero
 *	will remain unchanged.
 *	Returns a negative error code or zero. An error code must be returned
 *	if at least one unsupported change was requested.
 * @get_channels: Get number of channels.
 * @set_channels: Set number of channels.  Returns a negative error code or
 *	zero.
 * @get_dump_flag: Get dump flag indicating current dump length, version,
 * 		   and flag of the device.
 * @get_dump_data: Get dump data.
 * @set_dump: Set dump specific flags to the device.
 * @get_ts_info: Get the time stamping and PTP hardware clock capabilities.
 *	Drivers supporting transmit time stamps in software should set this to
 *	ethtool_op_get_ts_info().
 * @get_module_info: Get the size and type of the eeprom contained within
 *	a plug-in module.
 * @get_module_eeprom: Get the eeprom information from the plug-in module
 * @get_eee: Get Energy-Efficient (EEE) supported and status.
 * @set_eee: Set EEE status (enable/disable) as well as LPI timers.
 * @get_per_queue_coalesce: Get interrupt coalescing parameters per queue.
 *	It must check that the given queue number is valid. If neither a RX nor
 *	a TX queue has this number, return -EINVAL. If only a RX queue or a TX
 *	queue has this number, set the inapplicable fields to ~0 and return 0.
 *	Returns a negative error code or zero.
 *
 * All operations are optional (i.e. the function pointer may be set
 * to %NULL) and callers must take this into account.  Callers must
 * hold the RTNL lock.
 *
 * See the structures used by these operations for further documentation.
 * Note that for all operations using a structure ending with a zero-
 * length array, the array is allocated separately in the kernel and
 * is passed to the driver as an additional parameter.
 *
 * See &struct net_device and &struct net_device_ops for documentation
 * of the generic netdev features interface.

892311f6 EP	182	* and/or hash function.
8717d07b	183	* Returns a negative error code or zero.
892311f6 EP	184	* @set_rxfh: Set the contents of the RX flow hash indirection table, hash
	185	* key, and/or hash function. Arguments which are set to %NULL or zero
	186	* will remain unchanged.
	187	* Returns a negative error code or zero. An error code must be returned
	188	* if at least one unsupported change was requested.
8b5933c3	189	* @get_channels: Get number of channels.
	190	* @set_channels: Set number of channels. Returns a negative error code or
	191	* zero.
29dd54b7 AC	192	* @get_dump_flag: Get dump flag indicating current dump length, version,
	193	* and flag of the device.
	194	* @get_dump_data: Get dump data.
	195	* @set_dump: Set dump specific flags to the device.
c8f3a8c3 RC	196	* @get_ts_info: Get the time stamping and PTP hardware clock capabilities.
	197	* Drivers supporting transmit time stamps in software should set this to
	198	* ethtool_op_get_ts_info().
41c3cb6d SH	199	* @get_module_info: Get the size and type of the eeprom contained within
	200	* a plug-in module.
	201	* @get_module_eeprom: Get the eeprom information from the plug-in module

80f12ecc YM	203	* @set_eee: Set EEE status (enable/disable) as well as LPI timers.
421797b1 KL	204	* @get_per_queue_coalesce: Get interrupt coalescing parameters per queue.
	205	* It must check that the given queue number is valid. If neither a RX nor
	206	* a TX queue has this number, return -EINVAL. If only a RX queue or a TX
	207	* queue has this number, set the inapplicable fields to ~0 and return 0.
	208	* Returns a negative error code or zero.
8717d07b BH	209	*
	210	* All operations are optional (i.e. the function pointer may be set
	211	* to %NULL) and callers must take this into account. Callers must
b4f79e5c	212	* hold the RTNL lock.
8717d07b BH	213	*
8717d07b BH	214	* See the structures used by these operations for further documentation.
6e201c85 BH	215	* Note that for all operations using a structure ending with a zero-
	216	* length array, the array is allocated separately in the kernel and
	217	* is passed to the driver as an additional parameter.
