| * 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_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. | |
| * 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. | |
| * 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 | |
