/**
* struct ethtool_ops - optional netdev operations
* @get_settings: Get various device settings including Ethernet link
* settings. The @cmd parameter is expected to have been cleared
* before get_settings is called. Returns a negative error code or
* 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.
* @get_msglevel: Report driver message level. This should be the value
* 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
* error code or zero.
* @set_coalesce: Set interrupt coalescing parameters. Returns a negative
* error code or zero.
* @get_ringparam: Report ring sizes
* @set_ringparam: Set ring sizes. Returns a negative error code or zero.
* @get_pauseparam: Report pause parameters
* @set_pauseparam: Set pause parameters. Returns a negative error code
* or zero.
* @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.
* @set_priv_flags: Set driver-specific feature flags. Returns a negative
* error code or zero.
* @get_sset_count: Get number of strings that @get_strings will write.
* @get_rxnfc: Get RX flow classification rules. Returns a negative
* error code or zero.
* @set_rxnfc: Set RX flow classification rules. Returns a negative
* error code or zero.
* @flash_device: Write a firmware image to device's flash memory.
* Returns a negative error code or zero.
* @reset: Reset (part of) the device, as specified by a bitmask of
* 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_indir: Get the contents of the RX flow hash indirection table.
* Will not be called if @get_rxfh_indir_size returns zero.
* @get_rxfh: Get the contents of the RX flow hash indirection table and hash
* key.
* Will not be called if @get_rxfh_indir_size and @get_rxfh_key_size
* returns zero.
* Returns a negative error code or zero.
* @set_rxfh_indir: Set the contents of the RX flow hash indirection table.
* Will not be called if @get_rxfh_indir_size returns zero.
* @set_rxfh: Set the contents of the RX flow hash indirection table and
* hash key.
* Will not be called if @get_rxfh_indir_size and @get_rxfh_key_size
* returns zero.
* Returns a negative error code or zero.
* @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.
*
* 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.
*
* See &struct net_device and &struct net_device_ops for documentation
* of the generic netdev features interface.
