38	* struct ethtool_cmd - DEPRECATED, link control and status
39	* This structure is DEPRECATED, please use struct ethtool_link_settings.
40	* @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
41	* @supported: Bitmask of %SUPPORTED_* flags for the link modes,
42	* physical connectors and other link features for which the
43	* interface supports autonegotiation or auto-detection.
44	* Read-only.
45	* @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
46	* physical connectors and other link features that are
47	* advertised through autonegotiation or enabled for
48	* auto-detection.
49	* @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
50	* @duplex: Duplex mode; one of %DUPLEX_*
51	* @port: Physical connector type; one of %PORT_*
52	* @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
53	* applicable. For clause 45 PHYs this is the PRTAD.
54	* @transceiver: Historically used to distinguish different possible
55	* PHY types, but not in a consistent way. Deprecated.
56	* @autoneg: Enable/disable autonegotiation and auto-detection;
57	* either %AUTONEG_DISABLE or %AUTONEG_ENABLE
58	* @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
59	* protocols supported by the interface; 0 if unknown.
60	* Read-only.
61	* @maxtxpkt: Historically used to report TX IRQ coalescing; now
62	* obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
63	* @maxrxpkt: Historically used to report RX IRQ coalescing; now
64	* obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
65	* @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
66	* @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
67	* %ETH_TP_MDI_*. If the status is unknown or not applicable, the
68	* value will be %ETH_TP_MDI_INVALID. Read-only.
69	* @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
70	* %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
71	* yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
72	* When written successfully, the link should be renegotiated if
73	* necessary.
74	* @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
75	* and other link features that the link partner advertised
76	* through autonegotiation; 0 if unknown or not applicable.
77	* Read-only.
78	* @reserved: Reserved for future use; see the note on reserved space.
79	*
80	* The link speed in Mbps is split between @speed and @speed_hi. Use
81	* the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
82	* access it.
83	*
84	* If autonegotiation is disabled, the speed and @duplex represent the
85	* fixed link mode and are writable if the driver supports multiple
86	* link modes. If it is enabled then they are read-only; if the link
87	* is up they represent the negotiated link mode; if the link is down,
88	* the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
89	* @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
90	*
91	* Some hardware interfaces may have multiple PHYs and/or physical
92	* connectors fitted or do not allow the driver to detect which are
93	* fitted. For these interfaces @port and/or @phy_address may be
94	* writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
95	* Otherwise, attempts to write different values may be ignored or
96	* rejected.
97	*
98	* Users should assume that all fields not marked read-only are
99	* writable and subject to validation by the driver. They should use
100	* %ETHTOOL_GSET to get the current values before making specific
101	* changes and then applying them with %ETHTOOL_SSET.
102	*
103	* Deprecated fields should be ignored by both users and drivers.

2020	* @supported: Bitmap with each bit meaning given by
2021	* %ethtool_link_mode_bit_indices for the link modes, physical
2022	* connectors and other link features for which the interface
2023	* supports autonegotiation or auto-detection. Read-only.
2024	* @advertising: Bitmap with each bit meaning given by
2025	* %ethtool_link_mode_bit_indices for the link modes, physical
2026	* connectors and other link features that are advertised through
2027	* autonegotiation or enabled for auto-detection.
2028	* @lp_advertising: Bitmap with each bit meaning given by
2029	* %ethtool_link_mode_bit_indices for the link modes, and other
2030	* link features that the link partner advertised through
2031	* autonegotiation; 0 if unknown or not applicable. Read-only.
2032	* @transceiver: Used to distinguish different possible PHY types,
2033	* reported consistently by PHYLIB. Read-only.
2034	* @master_slave_cfg: Master/slave port mode.
2035	* @master_slave_state: Master/slave port state.
2036	* @reserved: Reserved for future use; see the note on reserved space.
2037	* @reserved1: Reserved for future use; see the note on reserved space.
2038	* @link_mode_masks: Variable length bitmaps.
2039	*
2040	* If autonegotiation is disabled, the speed and @duplex represent the
2041	* fixed link mode and are writable if the driver supports multiple
2042	* link modes. If it is enabled then they are read-only; if the link
2043	* is up they represent the negotiated link mode; if the link is down,
2044	* the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2045	* @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2046	*
2047	* Some hardware interfaces may have multiple PHYs and/or physical
2048	* connectors fitted or do not allow the driver to detect which are
2049	* fitted. For these interfaces @port and/or @phy_address may be
2050	* writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2051	* Otherwise, attempts to write different values may be ignored or
2052	* rejected.
2053	*
2054	* Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2055	* are not available in %ethtool_link_settings. These fields will be
2056	* always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2057	* fail if any of them is set to non-zero value.
2058	*
2059	* Users should assume that all fields not marked read-only are
2060	* writable and subject to validation by the driver. They should use
2061	* %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2062	* changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2063	*
2064	* Drivers that implement %get_link_ksettings and/or
2065	* %set_link_ksettings should ignore the @cmd
2066	* and @link_mode_masks_nwords fields (any change to them overwritten
2067	* by kernel), and rely only on kernel's internal
2068	* %__ETHTOOL_LINK_MODE_MASK_NBITS and
2069	* %ethtool_link_mode_mask_t. Drivers that implement
2070	* %set_link_ksettings() should validate all fields other than @cmd
2071	* and @link_mode_masks_nwords that are not described as read-only or
2072	* deprecated, and must ignore all fields described as read-only.
