+ * struct ethtool_ops - optional netdev operations
+ * @get_settings: DEPRECATED, use %get_link_ksettings/%set_link_ksettings
+ * API. 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: DEPRECATED, use %get_link_ksettings/%set_link_ksettings
+ * API. 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: 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.
+ * @set_per_queue_coalesce: Set 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, ignore the inapplicable fields.
+ * Returns a negative error code or zero.
+ * @get_link_ksettings: When defined, takes precedence over the
+ * %get_settings method. Get various device settings
+ * including Ethernet link settings. The %cmd and
+ * %link_mode_masks_nwords fields should be ignored (use
+ * %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter), any
+ * change to them will be overwritten by kernel. Returns a
+ * negative error code or zero.
+ * @set_link_ksettings: When defined, takes precedence over the
+ * %set_settings method. Set various device settings including
+ * Ethernet link settings. The %cmd and %link_mode_masks_nwords
+ * fields should be ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS
+ * instead of the latter), any change to them will be overwritten
+ * by kernel. Returns a negative error code or zero.
+ * @get_fecparam: Get the network device Forward Error Correction parameters.
+ * @set_fecparam: Set the network device Forward Error Correction parameters.
+ * @get_ethtool_phy_stats: Return extended statistics about the PHY device.
+ * This is only useful if the device maintains PHY statistics and
+ * cannot use the standard PHY library helpers.
+ *
+ * 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.
