  47.  * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
  48.  * @duplex: Duplex mode; one of %DUPLEX_*
  49.  * @port: Physical connector type; one of %PORT_*
  50.  * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
  51.  *	applicable.  For clause 45 PHYs this is the PRTAD.
  52.  * @transceiver: Historically used to distinguish different possible
  53.  *	PHY types, but not in a consistent way.  Deprecated.

  66.  *	value will be %ETH_TP_MDI_INVALID.  Read-only.
  67.  * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
  68.  *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
  69.  *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
  70.  *	When written successfully, the link should be renegotiated if
  71.  *	necessary.

  79.  * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
  80.  * access it.
  81.  *
  82.  * If autonegotiation is disabled, the speed and @duplex represent the
  83.  * fixed link mode and are writable if the driver supports multiple
  84.  * link modes.  If it is enabled then they are read-only; if the link
  85.  * is up they represent the negotiated link mode; if the link is down,
  86.  * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
  87.  * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
  88.  *
  89.  * Some hardware interfaces may have multiple PHYs and/or physical
  90.  * connectors fitted or do not allow the driver to detect which are
  91.  * fitted.  For these interfaces @port and/or @phy_address may be
  92.  * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
  93.  * Otherwise, attempts to write different values may be ignored or
  94.  * rejected.
  95.  *
  96.  * Users should assume that all fields not marked read-only are
  97.  * writable and subject to validation by the driver.  They should use
