/**
 * struct ethtool_ops - optional netdev operations
 * @get_settings: Get various device settings including Ethernet link
 *	settings.  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.
 * @get_rx_csum: Deprecated in favour of the netdev feature %NETIF_F_RXCSUM.
 *	Report whether receive checksums are turned on or off.
 * @set_rx_csum: Deprecated in favour of generic netdev features.  Turn
 *	receive checksum on or off.  Returns a negative error code or zero.
 * @get_tx_csum: Deprecated as redundant. Report whether transmit checksums
 *	are turned on or off.
 * @set_tx_csum: Deprecated in favour of generic netdev features.  Turn
 *	transmit checksums on or off.  Returns a egative error code or zero.
 * @get_sg: Deprecated as redundant.  Report whether scatter-gather is
 *	enabled.  
 * @set_sg: Deprecated in favour of generic netdev features.  Turn
 *	scatter-gather on or off. Returns a negative error code or zero.
 * @get_tso: Deprecated as redundant.  Report whether TCP segmentation
 *	offload is enabled.
 * @set_tso: Deprecated in favour of generic netdev features.  Turn TCP
 *	segmentation offload on or off.  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 or return -%EINVAL.
 *	If it returns -%EINVAL then it will be called again at intervals with
 *	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.
 * @phys_id: Deprecated in favour of @set_phys_id.
 *	Identify the physical device, e.g. by flashing an LED
 *	attached to it until interrupted by a signal or the given time
 *	(in seconds) elapses.  If the given time is zero, use a default
 *	time limit.  Returns a negative error code or zero.  Being
 *	interrupted by a signal is not an error.
 * @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_ufo: Deprecated as redundant.  Report whether UDP fragmentation
 *	offload is enabled.
 * @set_ufo: Deprecated in favour of generic netdev features.  Turn UDP
 *	fragmentation offload on or off.  Returns a negative error code or zero.
 * @get_flags: Deprecated as redundant.  Report features included in
 *	&enum ethtool_flags that are enabled.  
 * @set_flags: Deprecated in favour of generic netdev features.  Turn
 *	features included in &enum ethtool_flags on or off.  Returns a
 *	negative error code or zero.
 * @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.

 *	flags from &enum ethtool_reset_flags.  Returns a negative
 *	error code or zero.
 * @set_rx_ntuple: Set an RX n-tuple rule.  Returns a negative error code
 *	or zero.
 * @get_rx_ntuple: Deprecated.
 * @get_rxfh_indir: Get the contents of the RX flow hash indirection table.
 *	Returns a negative error code or zero.
 * @set_rxfh_indir: Set the contents of the RX flow hash indirection table.
 *	Returns a negative error code or zero.
 *
 * 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, except that for @get_drvinfo the caller may or may
 * not hold the RTNL.
