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.

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. + * @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 and hash + *	key. + *	Will only be called if one or both of @get_rxfh_indir_size and + *	@get_rxfh_key_size are implemented and return non-zero. + *	Returns a negative error code or zero. + * @set_rxfh: Set the contents of the RX flow hash indirection table and/or + *	hash key.  In case only the indirection table or hash key is to be + *	changed, the other argument will be %NULL. + *	Will only be called if one or both of @get_rxfh_indir_size and + *	@get_rxfh_key_size are implemented and return non-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. + * 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.   */  struct ethtool_ops {  	int	(*get_settings)(struct net_device *, struct ethtool_cmd *);
