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.

447  *	sampling, measured in seconds.  Must not be zero.

455  * would cause interrupts to never be generated.  To disable
456  * coalescing, set usecs = 0 and max_frames = 1.
457  *

467  * one of RX or TX adaptive coalescing.  Anything not implemented by
468  * the driver causes these values to be silently ignored.
469  *
470  * When the packet rate is below @pkt_rate_high but above
471  * @pkt_rate_low (both measured in packets per second) the
472  * normal {rx,tx}_* coalescing parameters are used.

1931  *	Read-only.
1932  * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
1933  *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
1934  *	value will be %ETH_TP_MDI_INVALID.  Read-only.
1935  * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
1936  *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
1937  *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
1938  *	When written successfully, the link should be renegotiated if
1939  *	necessary.
1940  * @link_mode_masks_nwords: Number of 32-bit words for each of the
1941  *	supported, advertising, lp_advertising link mode bitmaps. For
1942  *	%ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
1943  *	(>= 0); on return, if handshake in progress, negative if
1944  *	request size unsupported by kernel: absolute value indicates
1945  *	kernel expected size and all the other fields but cmd
1946  *	are 0; otherwise (handshake completed), strictly positive
1947  *	to indicate size used by kernel and cmd field stays
1948  *	%ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
1949  *	%ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
1950  *	value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
1951  *	refused. For drivers: ignore this field (use kernel's
1952  *	__ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1953  *	be overwritten by kernel.
1954  * @supported: Bitmap with each bit meaning given by
1955  *	%ethtool_link_mode_bit_indices for the link modes, physical
1956  *	connectors and other link features for which the interface
1957  *	supports autonegotiation or auto-detection.  Read-only.
1958  * @advertising: Bitmap with each bit meaning given by
1959  *	%ethtool_link_mode_bit_indices for the link modes, physical
1960  *	connectors and other link features that are advertised through
1961  *	autonegotiation or enabled for auto-detection.
1962  * @lp_advertising: Bitmap with each bit meaning given by
1963  *	%ethtool_link_mode_bit_indices for the link modes, and other
1964  *	link features that the link partner advertised through
1965  *	autonegotiation; 0 if unknown or not applicable.  Read-only.
1966  * @transceiver: Used to distinguish different possible PHY types,
1967  *	reported consistently by PHYLIB.  Read-only.
1968  * @master_slave_cfg: Master/slave port mode.
1969  * @master_slave_state: Master/slave port state.
1970  * @reserved: Reserved for future use; see the note on reserved space.
1971  * @reserved1: Reserved for future use; see the note on reserved space.
1972  * @link_mode_masks: Variable length bitmaps.
1973  *
1974  * If autonegotiation is disabled, the speed and @duplex represent the
1975  * fixed link mode and are writable if the driver supports multiple
1976  * link modes.  If it is enabled then they are read-only; if the link
1977  * is up they represent the negotiated link mode; if the link is down,
1978  * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1979  * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1980  *
1981  * Some hardware interfaces may have multiple PHYs and/or physical
1982  * connectors fitted or do not allow the driver to detect which are
1983  * fitted.  For these interfaces @port and/or @phy_address may be
1984  * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1985  * Otherwise, attempts to write different values may be ignored or
1986  * rejected.
1987  *
1988  * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1989  * are not available in %ethtool_link_settings. These fields will be
1990  * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
1991  * fail if any of them is set to non-zero value.
1992  *
1993  * Users should assume that all fields not marked read-only are
1994  * writable and subject to validation by the driver.  They should use
1995  * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1996  * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1997  *
1998  * Drivers that implement %get_link_ksettings and/or
1999  * %set_link_ksettings should ignore the @cmd
2000  * and @link_mode_masks_nwords fields (any change to them overwritten
2001  * by kernel), and rely only on kernel's internal
2002  * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2003  * %ethtool_link_mode_mask_t. Drivers that implement
2004  * %set_link_ksettings() should validate all fields other than @cmd
2005  * and @link_mode_masks_nwords that are not described as read-only or
2006  * deprecated, and must ignore all fields described as read-only.
