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.
