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

1630  * struct ethtool_link_settings - link control and status
1631  *
1632  * IMPORTANT, Backward compatibility notice: When implementing new
1633  *	user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and
1634  *	if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
1635  *	settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
1636  *	succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
1637  *	that case.  Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
1638  *	%ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
1639  *	settings; do not use %ETHTOOL_SLINKSETTINGS if
1640  *	%ETHTOOL_GLINKSETTINGS failed: stick to
1641  *	%ETHTOOL_GSET/%ETHTOOL_SSET in that case.
1642  *
1643  * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
1644  * @speed: Link speed (Mbps)
1645  * @duplex: Duplex mode; one of %DUPLEX_*
1646  * @port: Physical connector type; one of %PORT_*
1647  * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
1648  *	applicable.  For clause 45 PHYs this is the PRTAD.
1649  * @autoneg: Enable/disable autonegotiation and auto-detection;
1650  *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
1651  * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
1652  *	protocols supported by the interface; 0 if unknown.
1653  *	Read-only.
1654  * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
1655  *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
1656  *	value will be %ETH_TP_MDI_INVALID.  Read-only.
1657  * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
1658  *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
1659  *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
1660  *	When written successfully, the link should be renegotiated if
1661  *	necessary.
1662  * @link_mode_masks_nwords: Number of 32-bit words for each of the
1663  *	supported, advertising, lp_advertising link mode bitmaps. For
1664  *	%ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
1665  *	(>= 0); on return, if handshake in progress, negative if
1666  *	request size unsupported by kernel: absolute value indicates
1667  *	kernel expected size and all the other fields but cmd
1668  *	are 0; otherwise (handshake completed), strictly positive
1669  *	to indicate size used by kernel and cmd field stays
1670  *	%ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
1671  *	%ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
1672  *	value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
1673  *	refused. For drivers: ignore this field (use kernel's
1674  *	__ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1675  *	be overwritten by kernel.
1676  * @supported: Bitmap with each bit meaning given by
1677  *	%ethtool_link_mode_bit_indices for the link modes, physical
1678  *	connectors and other link features for which the interface
1679  *	supports autonegotiation or auto-detection.  Read-only.
1680  * @advertising: Bitmap with each bit meaning given by
1681  *	%ethtool_link_mode_bit_indices for the link modes, physical
1682  *	connectors and other link features that are advertised through
1683  *	autonegotiation or enabled for auto-detection.
1684  * @lp_advertising: Bitmap with each bit meaning given by
1685  *	%ethtool_link_mode_bit_indices for the link modes, and other
1686  *	link features that the link partner advertised through
1687  *	autonegotiation; 0 if unknown or not applicable.  Read-only.
1688  *
1689  * If autonegotiation is disabled, the speed and @duplex represent the
1690  * fixed link mode and are writable if the driver supports multiple
1691  * link modes.  If it is enabled then they are read-only; if the link
1692  * is up they represent the negotiated link mode; if the link is down,
1693  * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1694  * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1695  *
1696  * Some hardware interfaces may have multiple PHYs and/or physical
1697  * connectors fitted or do not allow the driver to detect which are
1698  * fitted.  For these interfaces @port and/or @phy_address may be
1699  * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1700  * Otherwise, attempts to write different values may be ignored or
1701  * rejected.
1702  *
1703  * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1704  * are not available in %ethtool_link_settings. Until all drivers are
1705  * converted to ignore them or to the new %ethtool_link_settings API,
1706  * for both queries and changes, users should always try
1707  * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick
1708  * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it
1709  * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and
1710  * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing
1711  * either %ethtool_cmd or %ethtool_link_settings).
1712  *
1713  * Users should assume that all fields not marked read-only are
1714  * writable and subject to validation by the driver.  They should use
1715  * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1716  * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1717  *
1718  * Drivers that implement %get_link_ksettings and/or
1719  * %set_link_ksettings should ignore the @cmd
1720  * and @link_mode_masks_nwords fields (any change to them overwritten
1721  * by kernel), and rely only on kernel's internal
1722  * %__ETHTOOL_LINK_MODE_MASK_NBITS and
1723  * %ethtool_link_mode_mask_t. Drivers that implement
1724  * %set_link_ksettings() should validate all fields other than @cmd
1725  * and @link_mode_masks_nwords that are not described as read-only or
1726  * deprecated, and must ignore all fields described as read-only.
