/**
* 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.

*
* 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

* @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

* 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

/**
* struct ethtool_link_settings - link control and status
*
* IMPORTANT, Backward compatibility notice: When implementing new
* user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and
* if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
* settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
* succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
* that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
* %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
* settings; do not use %ETHTOOL_SLINKSETTINGS if
* %ETHTOOL_GLINKSETTINGS failed: stick to
* %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
*
* @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
* @speed: Link speed (Mbps)
* @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.
* @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.
* @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.
* @link_mode_masks_nwords: Number of 32-bit words for each of the
* supported, advertising, lp_advertising link mode bitmaps. For
* %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
* (>= 0); on return, if handshake in progress, negative if
* request size unsupported by kernel: absolute value indicates
* kernel expected size and all the other fields but cmd
* are 0; otherwise (handshake completed), strictly positive
* to indicate size used by kernel and cmd field stays
* %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
* %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
* value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
* refused. For drivers: ignore this field (use kernel's
* __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
* be overwritten by kernel.
* @supported: Bitmap with each bit meaning given by
* %ethtool_link_mode_bit_indices for the link modes, physical
* connectors and other link features for which the interface
* supports autonegotiation or auto-detection. Read-only.
* @advertising: Bitmap with each bit meaning given by
* %ethtool_link_mode_bit_indices for the link modes, physical
* 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.
