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

2463	* struct ethtool_link_settings - link control and status
2464	*
2465	* IMPORTANT, Backward compatibility notice: When implementing new
2466	* user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and
2467	* if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
2468	* settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
2469	* succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
2470	* that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
2471	* %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
2472	* settings; do not use %ETHTOOL_SLINKSETTINGS if
2473	* %ETHTOOL_GLINKSETTINGS failed: stick to
2474	* %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
2475	*
2476	* @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
2477	* @speed: Link speed (Mbps)
2478	* @duplex: Duplex mode; one of %DUPLEX_*
2479	* @port: Physical connector type; one of %PORT_*
2480	* @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
2481	* applicable. For clause 45 PHYs this is the PRTAD.
2482	* @autoneg: Enable/disable autonegotiation and auto-detection;
2483	* either %AUTONEG_DISABLE or %AUTONEG_ENABLE
2484	* @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
2485	* protocols supported by the interface; 0 if unknown.
2486	* Read-only.
2487	* @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
2488	* %ETH_TP_MDI_*. If the status is unknown or not applicable, the
2489	* value will be %ETH_TP_MDI_INVALID. Read-only.
2490	* @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2491	* %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
2492	* yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2493	* When written successfully, the link should be renegotiated if
2494	* necessary.
2495	* @link_mode_masks_nwords: Number of 32-bit words for each of the
2496	* supported, advertising, lp_advertising link mode bitmaps. For
2497	* %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2498	* (>= 0); on return, if handshake in progress, negative if
2499	* request size unsupported by kernel: absolute value indicates
2500	* kernel expected size and all the other fields but cmd
2501	* are 0; otherwise (handshake completed), strictly positive
2502	* to indicate size used by kernel and cmd field stays
2503	* %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2504	* %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2505	* value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2506	* refused. For drivers: ignore this field (use kernel's
2507	* __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2508	* be overwritten by kernel.
2509	* @transceiver: Used to distinguish different possible PHY types,
2510	* reported consistently by PHYLIB. Read-only.
2511	* @master_slave_cfg: Master/slave port mode.
2512	* @master_slave_state: Master/slave port state.
2513	* @rate_matching: Rate adaptation performed by the PHY
2514	* @reserved: Reserved for future use; see the note on reserved space.
2515	* @link_mode_masks: Variable length bitmaps.
2516	*
2517	* If autonegotiation is disabled, the speed and @duplex represent the
2518	* fixed link mode and are writable if the driver supports multiple
2519	* link modes. If it is enabled then they are read-only; if the link
2520	* is up they represent the negotiated link mode; if the link is down,
2521	* the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2522	* @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2523	*
2524	* Some hardware interfaces may have multiple PHYs and/or physical
2525	* connectors fitted or do not allow the driver to detect which are
2526	* fitted. For these interfaces @port and/or @phy_address may be
2527	* writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2528	* Otherwise, attempts to write different values may be ignored or
2529	* rejected.
2530	*
2531	* Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2532	* are not available in %ethtool_link_settings. These fields will be
2533	* always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2534	* fail if any of them is set to non-zero value.
2535	*
2536	* Users should assume that all fields not marked read-only are
2537	* writable and subject to validation by the driver. They should use
2538	* %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2539	* changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2540	*
2541	* Drivers that implement %get_link_ksettings and/or
2542	* %set_link_ksettings should ignore the @cmd
2543	* and @link_mode_masks_nwords fields (any change to them overwritten
2544	* by kernel), and rely only on kernel's internal
2545	* %__ETHTOOL_LINK_MODE_MASK_NBITS and
2546	* %ethtool_link_mode_mask_t. Drivers that implement
2547	* %set_link_ksettings() should validate all fields other than @cmd
2548	* and @link_mode_masks_nwords that are not described as read-only or
2549	* deprecated, and must ignore all fields described as read-only.
2550	*
2551	* @link_mode_masks is divided into three bitfields, each of length
2552	* @link_mode_masks_nwords:
2553	* - supported: Bitmap with each bit meaning given by
2554	* %ethtool_link_mode_bit_indices for the link modes, physical
2555	* connectors and other link features for which the interface
2556	* supports autonegotiation or auto-detection. Read-only.
2557	* - advertising: Bitmap with each bit meaning given by
2558	* %ethtool_link_mode_bit_indices for the link modes, physical
2559	* connectors and other link features that are advertised through
2560	* autonegotiation or enabled for auto-detection.
2561	* - lp_advertising: Bitmap with each bit meaning given by
2562	* %ethtool_link_mode_bit_indices for the link modes, and other
2563	* link features that the link partner advertised through
2564	* autonegotiation; 0 if unknown or not applicable. Read-only.
