 /**
  * 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.

  * 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

  * %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

 /**
  * 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.
  * @master_slave_cfg: Master/slave port mode.
  * @master_slave_state: Master/slave port state.
  * @reserved: Reserved for future use; see the note on reserved space.
  * @reserved1: 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.
