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

2108 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
2109 * value will be %ETH_TP_MDI_INVALID. Read-only.
2110 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2111 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
2112 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2113 * When written successfully, the link should be renegotiated if
2114 * necessary.
2115 * @link_mode_masks_nwords: Number of 32-bit words for each of the
2116 * supported, advertising, lp_advertising link mode bitmaps. For
2117 * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2118 * (>= 0); on return, if handshake in progress, negative if
2119 * request size unsupported by kernel: absolute value indicates
2120 * kernel expected size and all the other fields but cmd
2121 * are 0; otherwise (handshake completed), strictly positive
2122 * to indicate size used by kernel and cmd field stays
2123 * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2124 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2125 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2126 * refused. For drivers: ignore this field (use kernel's
2127 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2128 * be overwritten by kernel.
2129 * @supported: Bitmap with each bit meaning given by
2130 * %ethtool_link_mode_bit_indices for the link modes, physical
2131 * connectors and other link features for which the interface
2132 * supports autonegotiation or auto-detection. Read-only.
2133 * @advertising: Bitmap with each bit meaning given by
2134 * %ethtool_link_mode_bit_indices for the link modes, physical
2135 * connectors and other link features that are advertised through
2136 * autonegotiation or enabled for auto-detection.
2137 * @lp_advertising: Bitmap with each bit meaning given by
2138 * %ethtool_link_mode_bit_indices for the link modes, and other
2139 * link features that the link partner advertised through
2140 * autonegotiation; 0 if unknown or not applicable. Read-only.
2141 * @transceiver: Used to distinguish different possible PHY types,
2142 * reported consistently by PHYLIB. Read-only.
2143 * @master_slave_cfg: Master/slave port mode.
2144 * @master_slave_state: Master/slave port state.
2145 * @rate_matching: Rate adaptation performed by the PHY
2146 * @reserved: Reserved for future use; see the note on reserved space.
2147 * @link_mode_masks: Variable length bitmaps.
2148 *
2149 * If autonegotiation is disabled, the speed and @duplex represent the
2150 * fixed link mode and are writable if the driver supports multiple
2151 * link modes. If it is enabled then they are read-only; if the link
2152 * is up they represent the negotiated link mode; if the link is down,
2153 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2154 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2155 *
2156 * Some hardware interfaces may have multiple PHYs and/or physical
2157 * connectors fitted or do not allow the driver to detect which are
2158 * fitted. For these interfaces @port and/or @phy_address may be
2159 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2160 * Otherwise, attempts to write different values may be ignored or
2161 * rejected.
2162 *
2163 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2164 * are not available in %ethtool_link_settings. These fields will be
2165 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2166 * fail if any of them is set to non-zero value.
2167 *
2168 * Users should assume that all fields not marked read-only are
2169 * writable and subject to validation by the driver. They should use
2170 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2171 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2172 *
2173 * Drivers that implement %get_link_ksettings and/or
2174 * %set_link_ksettings should ignore the @cmd
2175 * and @link_mode_masks_nwords fields (any change to them overwritten
2176 * by kernel), and rely only on kernel's internal
2177 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2178 * %ethtool_link_mode_mask_t. Drivers that implement
2179 * %set_link_ksettings() should validate all fields other than @cmd
2180 * and @link_mode_masks_nwords that are not described as read-only or
2181 * deprecated, and must ignore all fields described as read-only.
