| * @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. |
| * |
| * 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 |
