/**
 * 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.

/**
 * 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.
 * @transceiver: Used to distinguish different possible PHY types,
 *	reported consistently by PHYLIB.  Read-only.
 * @master_slave_cfg: Master/slave port mode.
 * @master_slave_state: Master/slave port state.
 * @rate_matching: Rate adaptation performed by the PHY
 * @reserved: Reserved for future use; see the note on reserved space.
 * @link_mode_masks: Variable length bitmaps.
 *
 * 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.
 *
 * @link_mode_masks is divided into three bitfields, each of length
 * @link_mode_masks_nwords:
 * - 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.
