/** |
|
* 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: 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. |
|
* |
|
* 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. |
