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.

2416  *	succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in

2419  *	settings; do not use %ETHTOOL_SLINKSETTINGS if
2420  *	%ETHTOOL_GLINKSETTINGS failed: stick to
2421  *	%ETHTOOL_GSET/%ETHTOOL_SSET in that case.
2422  *
2423  * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
2424  * @speed: Link speed (Mbps)
2425  * @duplex: Duplex mode; one of %DUPLEX_*
2426  * @port: Physical connector type; one of %PORT_*
2427  * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
2428  *	applicable.  For clause 45 PHYs this is the PRTAD.
2429  * @autoneg: Enable/disable autonegotiation and auto-detection;
2430  *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
2431  * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
2432  *	protocols supported by the interface; 0 if unknown.
2433  *	Read-only.
2434  * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
2435  *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
2436  *	value will be %ETH_TP_MDI_INVALID.  Read-only.
2437  * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2438  *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
2439  *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2440  *	When written successfully, the link should be renegotiated if
2441  *	necessary.
2442  * @link_mode_masks_nwords: Number of 32-bit words for each of the
2443  *	supported, advertising, lp_advertising link mode bitmaps. For
2444  *	%ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2445  *	(>= 0); on return, if handshake in progress, negative if
2446  *	request size unsupported by kernel: absolute value indicates
2447  *	kernel expected size and all the other fields but cmd
2448  *	are 0; otherwise (handshake completed), strictly positive
2449  *	to indicate size used by kernel and cmd field stays
2450  *	%ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2451  *	%ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2452  *	value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2453  *	refused. For drivers: ignore this field (use kernel's
2454  *	__ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2455  *	be overwritten by kernel.
2456  * @transceiver: Used to distinguish different possible PHY types,
2457  *	reported consistently by PHYLIB.  Read-only.
2458  * @master_slave_cfg: Master/slave port mode.
2459  * @master_slave_state: Master/slave port state.
2460  * @rate_matching: Rate adaptation performed by the PHY
2461  * @reserved: Reserved for future use; see the note on reserved space.
2462  * @link_mode_masks: Variable length bitmaps.
2463  *
2464  * If autonegotiation is disabled, the speed and @duplex represent the
2465  * fixed link mode and are writable if the driver supports multiple
2466  * link modes.  If it is enabled then they are read-only; if the link
2467  * is up they represent the negotiated link mode; if the link is down,
2468  * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2469  * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2470  *
2471  * Some hardware interfaces may have multiple PHYs and/or physical
2472  * connectors fitted or do not allow the driver to detect which are
2473  * fitted.  For these interfaces @port and/or @phy_address may be
2474  * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2475  * Otherwise, attempts to write different values may be ignored or
2476  * rejected.
2477  *
2478  * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2479  * are not available in %ethtool_link_settings. These fields will be
2480  * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2481  * fail if any of them is set to non-zero value.
2482  *
2483  * Users should assume that all fields not marked read-only are
2484  * writable and subject to validation by the driver.  They should use
2485  * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2486  * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2487  *
2488  * Drivers that implement %get_link_ksettings and/or
2489  * %set_link_ksettings should ignore the @cmd
2490  * and @link_mode_masks_nwords fields (any change to them overwritten
2491  * by kernel), and rely only on kernel's internal
2492  * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2493  * %ethtool_link_mode_mask_t. Drivers that implement
2494  * %set_link_ksettings() should validate all fields other than @cmd
2495  * and @link_mode_masks_nwords that are not described as read-only or
2496  * deprecated, and must ignore all fields described as read-only.
2497  *
2498  * @link_mode_masks is divided into three bitfields, each of length
2499  * @link_mode_masks_nwords:
2500  * - supported: Bitmap with each bit meaning given by
2501  *	%ethtool_link_mode_bit_indices for the link modes, physical
2502  *	connectors and other link features for which the interface
2503  *	supports autonegotiation or auto-detection.  Read-only.
2504  * - advertising: Bitmap with each bit meaning given by
2505  *	%ethtool_link_mode_bit_indices for the link modes, physical
2506  *	connectors and other link features that are advertised through
2507  *	autonegotiation or enabled for auto-detection.
2508  * - lp_advertising: Bitmap with each bit meaning given by
2509  *	%ethtool_link_mode_bit_indices for the link modes, and other
2510  *	link features that the link partner advertised through
2511  *	autonegotiation; 0 if unknown or not applicable.  Read-only.
