/**
 * struct ethtool_cmd - DEPRECATED, link control and status
 * This structure is DEPRECATED, please use struct ethtool_link_settings.
 * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
 * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
 *	physical connectors and other link features for which the
 *	interface supports autonegotiation or auto-detection.
 *	Read-only.
 * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
 *	physical connectors and other link features that are
 *	advertised through autonegotiation or enabled for
 *	auto-detection.
 * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
 * @duplex: Duplex mode; one of %DUPLEX_*
 * @port: Physical connector type; one of %PORT_*
 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
 *	applicable.  For clause 45 PHYs this is the PRTAD.
 * @transceiver: Historically used to distinguish different possible
 *	PHY types, but not in a consistent way.  Deprecated.
 * @autoneg: Enable/disable autonegotiation and auto-detection;
 *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
 *	protocols supported by the interface; 0 if unknown.
 *	Read-only.
 * @maxtxpkt: Historically used to report TX IRQ coalescing; now
 *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
 * @maxrxpkt: Historically used to report RX IRQ coalescing; now
 *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
 * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
 *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
 *	value will be %ETH_TP_MDI_INVALID.  Read-only.
 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
 *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
 *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
 *	When written successfully, the link should be renegotiated if
 *	necessary.
 * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
 *	and other link features that the link partner advertised
 *	through autonegotiation; 0 if unknown or not applicable.
 *	Read-only.
 *
 * The link speed in Mbps is split between @speed and @speed_hi.  Use
 * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
 * access it.
 *
 * If autonegotiation is disabled, the speed and @duplex represent the
 * fixed link mode and are writable if the driver supports multiple
 * link modes.  If it is enabled then they are read-only; if the link
 * is up they represent the negotiated link mode; if the link is down,
 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
 *
 * Some hardware interfaces may have multiple PHYs and/or physical
 * connectors fitted or do not allow the driver to detect which are
 * fitted.  For these interfaces @port and/or @phy_address may be
 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
 * Otherwise, attempts to write different values may be ignored or
 * rejected.
 *
 * Users should assume that all fields not marked read-only are
 * writable and subject to validation by the driver.  They should use
 * %ETHTOOL_GSET to get the current values before making specific
 * changes and then applying them with %ETHTOOL_SSET.
 *
 * Deprecated fields should be ignored by both users and drivers.

 * struct ethtool_rxnfc - command to get or set RX flow classification rules
 * @cmd: Specific command number - %ETHTOOL_GRXFH, %ETHTOOL_SRXFH,
 *	%ETHTOOL_GRXRINGS, %ETHTOOL_GRXCLSRLCNT, %ETHTOOL_GRXCLSRULE,
 *	%ETHTOOL_GRXCLSRLALL, %ETHTOOL_SRXCLSRLDEL or %ETHTOOL_SRXCLSRLINS
 * @flow_type: Type of flow to be affected, e.g. %TCP_V4_FLOW
 * @data: Command-dependent value
 * @fs: Flow classification rule
 * @rss_context: RSS context to be affected
 * @rule_cnt: Number of rules to be affected
 * @rule_locs: Array of used rule locations
 *
 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating
 * the fields included in the flow hash, e.g. %RXH_IP_SRC.  The following
 * structure fields must not be used, except that if @flow_type includes
 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
 * act on.
 *
 * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
 * on return.
 *
 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined
 * rules on return.  If @data is non-zero on return then it is the
 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
 * driver supports any special location values.  If that flag is not
 * set in @data then special location values should not be used.
 *
 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an
 * existing rule on entry and @fs contains the rule on return; if
 * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is
 * filled with the RSS context ID associated with the rule.
 *
 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
 * user buffer for @rule_locs on entry.  On return, @data is the size
 * of the rule table, @rule_cnt is the number of defined rules, and
 * @rule_locs contains the locations of the defined rules.  Drivers
 * must use the second parameter to get_rxnfc() instead of @rule_locs.
 *
 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
 * @fs.@location either specifies the location to use or is a special
 * location value with %RX_CLS_LOC_SPECIAL flag set.  On return,
 * @fs.@location is the actual rule location.  If @fs.@flow_type
 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
 * use for flow spreading traffic which matches this rule.  The value
 * from the rxfh indirection table will be added to @fs.@ring_cookie
 * to choose which ring to deliver to.
 *
 * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
 * existing rule on entry.
 *
 * A driver supporting the special location values for
 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
 * location, and may remove a rule at a later location (lower
 * priority) that matches exactly the same set of flows.  The special
 * values are %RX_CLS_LOC_ANY, selecting any location;
 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable
 * location (minimum priority).  Additional special values may be
 * defined in future and drivers must return -%EINVAL for any
 * unrecognised value.

 *	connectors and other link features that are advertised through
 *	autonegotiation or enabled for auto-detection.
 * @lp_advertising: Bitmap with each bit meaning given by
 *	%ethtool_link_mode_bit_indices for the link modes, and other
 *	link features that the link partner advertised through
 *	autonegotiation; 0 if unknown or not applicable.  Read-only.
 * @transceiver: Used to distinguish different possible PHY types,
 *	reported consistently by PHYLIB.  Read-only.
 *
 * If autonegotiation is disabled, the speed and @duplex represent the
 * fixed link mode and are writable if the driver supports multiple
 * link modes.  If it is enabled then they are read-only; if the link
 * is up they represent the negotiated link mode; if the link is down,
 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
 *
 * Some hardware interfaces may have multiple PHYs and/or physical
 * connectors fitted or do not allow the driver to detect which are
 * fitted.  For these interfaces @port and/or @phy_address may be
 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
 * Otherwise, attempts to write different values may be ignored or
 * rejected.
 *
 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
 * are not available in %ethtool_link_settings. These fields will be
 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
 * fail if any of them is set to non-zero value.
 *
 * Users should assume that all fields not marked read-only are
 * writable and subject to validation by the driver.  They should use
 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
 *
 * Drivers that implement %get_link_ksettings and/or
 * %set_link_ksettings should ignore the @cmd
 * and @link_mode_masks_nwords fields (any change to them overwritten
 * by kernel), and rely only on kernel's internal
 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
 * %ethtool_link_mode_mask_t. Drivers that implement
 * %set_link_ksettings() should validate all fields other than @cmd
 * and @link_mode_masks_nwords that are not described as read-only or
 * deprecated, and must ignore all fields described as read-only.
