/**
* 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.
* @reserved: Reserved for future use; see the note on reserved space.
*
* 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.
