/**
 * struct ethtool_cmd - link control and status
 * @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
 * @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
 * @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.
 *
 * Drivers that implement set_settings() should validate all fields
 * other than @cmd that are not described as read-only or deprecated,
 * and must ignore all fields described as read-only.
 *
 * Deprecated fields should be ignored by both users and drivers.

 *      in-memory statistic block, and in such cases this value is
 *      ignored.  This value must not be zero.
 * @use_adaptive_rx_coalesce: Enable adaptive RX coalescing.
 * @use_adaptive_tx_coalesce: Enable adaptive TX coalescing.
 * @pkt_rate_low: Threshold for low packet rate (packets per second).

 * @rate_sample_interval: How often to do adaptive coalescing packet rate
 *      sampling, measured in seconds.  Must not be zero.
 *
 * Each pair of (usecs, max_frames) fields specifies that interrupts
 * should be coalesced until
 *      (usecs > 0 && time_since_first_completion >= usecs) ||
 *      (max_frames > 0 && completed_frames >= max_frames)
 *
 * It is illegal to set both usecs and max_frames to zero as this

 *
 * Some implementations ignore the value of max_frames and use the

 * counting completions should validate that max_frames == !rx_usecs.
 *
 * Adaptive RX/TX coalescing is an algorithm implemented by some
 * drivers to improve latency under low packet rates and improve

 * Returns >= 0 if request was completed; bits set in the value mean:
 *   %ETHTOOL_F_UNSUPPORTED - there were bits set in .valid that are not
 *      changeable (not present in %ETHTOOL_GFEATURES' features[].available)
 *      those bits were ignored.
 *   %ETHTOOL_F_WISH - some or all changes requested were recorded but the
 *      resulting state of bits masked by .valid is not equal to .requested.
 *      Probably there are other device-specific constraints on some features
 *      in the set. When %ETHTOOL_F_UNSUPPORTED is set, .valid is considered
 *      here as though ignored bits were cleared.
 *   %ETHTOOL_F_COMPAT - some or all changes requested were made by calling
 *      compatibility functions. Requested offload state cannot be properly
 *      managed by kernel.
 *
 * Meaning of bits in the masks are obtained by %ETHTOOL_GSSET_INFO (number of
