771 * settings. Returns a negative error code or zero.
772 * @get_drvinfo: Report driver/device information. Should only set the
773 * @driver, @version, @fw_version and @bus_info fields. If not

784 * @nway_reset: Restart autonegotiation. Returns a negative error code
786 * @get_link: Report whether physical link is up. Will only be called if
787 * the netdev is up. Should usually be set to ethtool_op_get_link(),
788 * which uses netif_carrier_ok().
789 * @get_eeprom: Read data from the device EEPROM.
790 * Should fill in the magic field. Don't need to check len for zero
791 * or wraparound. Fill in the data argument with the eeprom values
792 * from offset to offset + len. Update len to the amount read.
793 * Returns an error or zero.
794 * @set_eeprom: Write data to the device EEPROM.

829 * and must either activate asynchronous updates and return zero, return
830 * a negative error or return a positive frequency for synchronous
831 * indication (e.g. 1 for one on/off cycle per second). If it returns
832 * a frequency then it will be called again at intervals with the
833 * argument %ETHTOOL_ID_ON or %ETHTOOL_ID_OFF and should set the state of
834 * the indicator accordingly. Finally, it is called with the argument
835 * %ETHTOOL_ID_INACTIVE and must deactivate the indicator. Returns a
836 * negative error code or zero.

841 * negative error code or zero.

879 * @set_dump: Set dump specific flags to the device.
881 * All operations are optional (i.e. the function pointer may be set
