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

1930  *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
1931  *	When written successfully, the link should be renegotiated if
1932  *	necessary.
1933  * @link_mode_masks_nwords: Number of 32-bit words for each of the
1934  *	supported, advertising, lp_advertising link mode bitmaps. For
1935  *	%ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
1936  *	(>= 0); on return, if handshake in progress, negative if
1937  *	request size unsupported by kernel: absolute value indicates
1938  *	kernel expected size and all the other fields but cmd
1939  *	are 0; otherwise (handshake completed), strictly positive
1940  *	to indicate size used by kernel and cmd field stays
1941  *	%ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
1942  *	%ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
1943  *	value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
1944  *	refused. For drivers: ignore this field (use kernel's
1945  *	__ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1946  *	be overwritten by kernel.
1947  * @supported: Bitmap with each bit meaning given by
1948  *	%ethtool_link_mode_bit_indices for the link modes, physical
1949  *	connectors and other link features for which the interface
1950  *	supports autonegotiation or auto-detection.  Read-only.
1951  * @advertising: Bitmap with each bit meaning given by
1952  *	%ethtool_link_mode_bit_indices for the link modes, physical
1953  *	connectors and other link features that are advertised through
1954  *	autonegotiation or enabled for auto-detection.
1955  * @lp_advertising: Bitmap with each bit meaning given by
1956  *	%ethtool_link_mode_bit_indices for the link modes, and other
1957  *	link features that the link partner advertised through
1958  *	autonegotiation; 0 if unknown or not applicable.  Read-only.
1959  * @transceiver: Used to distinguish different possible PHY types,
1960  *	reported consistently by PHYLIB.  Read-only.
1961  *
1962  * If autonegotiation is disabled, the speed and @duplex represent the
1963  * fixed link mode and are writable if the driver supports multiple
1964  * link modes.  If it is enabled then they are read-only; if the link
1965  * is up they represent the negotiated link mode; if the link is down,
1966  * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1967  * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1968  *
1969  * Some hardware interfaces may have multiple PHYs and/or physical
1970  * connectors fitted or do not allow the driver to detect which are
1971  * fitted.  For these interfaces @port and/or @phy_address may be
1972  * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1973  * Otherwise, attempts to write different values may be ignored or
1974  * rejected.
1975  *
1976  * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1977  * are not available in %ethtool_link_settings. These fields will be
1978  * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
1979  * fail if any of them is set to non-zero value.
1980  *
1981  * Users should assume that all fields not marked read-only are
1982  * writable and subject to validation by the driver.  They should use
1983  * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1984  * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1985  *
1986  * Drivers that implement %get_link_ksettings and/or
1987  * %set_link_ksettings should ignore the @cmd
1988  * and @link_mode_masks_nwords fields (any change to them overwritten
1989  * by kernel), and rely only on kernel's internal
1990  * %__ETHTOOL_LINK_MODE_MASK_NBITS and
1991  * %ethtool_link_mode_mask_t. Drivers that implement
1992  * %set_link_ksettings() should validate all fields other than @cmd
1993  * and @link_mode_masks_nwords that are not described as read-only or
1994  * deprecated, and must ignore all fields described as read-only.
