     24  * struct ethtool_cmd - link control and status
     25  * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
     26  * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
     27  *	physical connectors and other link features for which the
     28  *	interface supports autonegotiation or auto-detection.
     29  *	Read-only.
     30  * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
     31  *	physical connectors and other link features that are
     32  *	advertised through autonegotiation or enabled for
     33  *	auto-detection.
     34  * @speed: Low bits of the speed
     35  * @duplex: Duplex mode; one of %DUPLEX_*
     36  * @port: Physical connector type; one of %PORT_*
     37  * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
     38  *	applicable.  For clause 45 PHYs this is the PRTAD.
     39  * @transceiver: Historically used to distinguish different possible
     40  *	PHY types, but not in a consistent way.  Deprecated.
     41  * @autoneg: Enable/disable autonegotiation and auto-detection;
     42  *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
     43  * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
     44  *	protocols supported by the interface; 0 if unknown.
     45  *	Read-only.
     46  * @maxtxpkt: Historically used to report TX IRQ coalescing; now
     47  *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
     48  * @maxrxpkt: Historically used to report RX IRQ coalescing; now
     49  *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
     50  * @speed_hi: High bits of the speed
     51  * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
     52  *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
     53  *	value will be %ETH_TP_MDI_INVALID.  Read-only.
     54  * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
     55  *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
     56  *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
     57  *	When written successfully, the link should be renegotiated if
     58  *	necessary.
     59  * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
     60  *	and other link features that the link partner advertised
     61  *	through autonegotiation; 0 if unknown or not applicable.
     62  *	Read-only.
     63  *
     64  * The link speed in Mbps is split between @speed and @speed_hi.  Use
     65  * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
     66  * access it.
     67  *
     68  * If autonegotiation is disabled, the speed and @duplex represent the
     69  * fixed link mode and are writable if the driver supports multiple
     70  * link modes.  If it is enabled then they are read-only; if the link
     71  * is up they represent the negotiated link mode; if the link is down,
     72  * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
     73  * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
     74  *
     75  * Some hardware interfaces may have multiple PHYs and/or physical
     76  * connectors fitted or do not allow the driver to detect which are
     77  * fitted.  For these interfaces @port and/or @phy_address may be
     78  * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
     79  * Otherwise, attempts to write different values may be ignored or
     80  * rejected.
     81  *
     82  * Users should assume that all fields not marked read-only are
     83  * writable and subject to validation by the driver.  They should use
     84  * %ETHTOOL_GSET to get the current values before making specific
     85  * changes and then applying them with %ETHTOOL_SSET.
     86  *
     87  * Drivers that implement set_settings() should validate all fields
     88  * other than @cmd that are not described as read-only or deprecated,
     89  * and must ignore all fields described as read-only.
     90  *
     91  * Deprecated fields should be ignored by both users and drivers.

    829  * @fs.@location either specifies the location to use or is a special
