36	* struct ethtool_cmd - DEPRECATED, link control and status
37	* This structure is DEPRECATED, please use struct ethtool_link_settings.
38	* @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
39	* @supported: Bitmask of %SUPPORTED_* flags for the link modes,
40	* physical connectors and other link features for which the
41	* interface supports autonegotiation or auto-detection.
42	* Read-only.
43	* @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
44	* physical connectors and other link features that are
45	* advertised through autonegotiation or enabled for
46	* auto-detection.
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.
54	* @autoneg: Enable/disable autonegotiation and auto-detection;
55	* either %AUTONEG_DISABLE or %AUTONEG_ENABLE
56	* @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
57	* protocols supported by the interface; 0 if unknown.
58	* Read-only.
59	* @maxtxpkt: Historically used to report TX IRQ coalescing; now
60	* obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
61	* @maxrxpkt: Historically used to report RX IRQ coalescing; now
62	* obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
63	* @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
64	* @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
65	* %ETH_TP_MDI_*. If the status is unknown or not applicable, the
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.
72	* @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
73	* and other link features that the link partner advertised
74	* through autonegotiation; 0 if unknown or not applicable.
75	* Read-only.
76	* @reserved: Reserved for future use; see the note on reserved space.
77	*
78	* The link speed in Mbps is split between @speed and @speed_hi. Use
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
98	* %ETHTOOL_GSET to get the current values before making specific
99	* changes and then applying them with %ETHTOOL_SSET.
100	*
101	* Deprecated fields should be ignored by both users and drivers.

1053	* For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating

1057	* act on.

1065	* driver supports any special location values. If that flag is not
1066	* set in @data then special location values should not be used.
1067	*
1068	* For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an

1075	* of the rule table, @rule_cnt is the number of defined rules, and

1077	* must use the second parameter to get_rxnfc() instead of @rule_locs.

1080	* @fs.@location either specifies the location to use or is a special
1081	* location value with %RX_CLS_LOC_SPECIAL flag set. On return,
1082	* @fs.@location is the actual rule location. If @fs.@flow_type
1083	* includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
1084	* use for flow spreading traffic which matches this rule. The value

2012	* @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2013	*
2014	* Some hardware interfaces may have multiple PHYs and/or physical
2015	* connectors fitted or do not allow the driver to detect which are
2016	* fitted. For these interfaces @port and/or @phy_address may be
2017	* writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2018	* Otherwise, attempts to write different values may be ignored or
2019	* rejected.
2020	*
2021	* Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2022	* are not available in %ethtool_link_settings. These fields will be
2023	* always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2024	* fail if any of them is set to non-zero value.
2025	*
2026	* Users should assume that all fields not marked read-only are
2027	* writable and subject to validation by the driver. They should use
2028	* %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2029	* changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2030	*
2031	* Drivers that implement %get_link_ksettings and/or
2032	* %set_link_ksettings should ignore the @cmd
2033	* and @link_mode_masks_nwords fields (any change to them overwritten
2034	* by kernel), and rely only on kernel's internal
2035	* %__ETHTOOL_LINK_MODE_MASK_NBITS and
2036	* %ethtool_link_mode_mask_t. Drivers that implement
2037	* %set_link_ksettings() should validate all fields other than @cmd
2038	* and @link_mode_masks_nwords that are not described as read-only or
2039	* deprecated, and must ignore all fields described as read-only.
