For 2186 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive 2187 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise 2188 * refused. For drivers: ignore this field (use kernel's 2189 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will 2190 * be overwritten by kernel. 2191 * @transceiver: Used to distinguish different possible PHY types, 2192 * reported consistently by PHYLIB. Read-only. 2193 * @master_slave_cfg: Master/slave port mode. 2194 * @master_slave_state: Master/slave port state. 2195 * @rate_matching: Rate adaptation performed by the PHY 2196 * @reserved: Reserved for future use; see the note on reserved space. 2197 * @link_mode_masks: Variable length bitmaps. 2198 * 2199 * If autonegotiation is disabled, the speed and @duplex represent the 2200 * fixed link mode and are writable if the driver supports multiple 2201 * link modes. If it is enabled then they are read-only; if the link 2202 * is up they represent the negotiated link mode; if the link is down, 2203 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and 2204 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. 2205 * 2206 * Some hardware interfaces may have multiple PHYs and/or physical 2207 * connectors fitted or do not allow the driver to detect which are 2208 * fitted. For these interfaces @port and/or @phy_address may be 2209 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. 2210 * Otherwise, attempts to write different values may be ignored or 2211 * rejected. 2212 * 2213 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt 2214 * are not available in %ethtool_link_settings. These fields will be 2215 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will 2216 * fail if any of them is set to non-zero value. 2217 * 2218 * Users should assume that all fields not marked read-only are 2219 * writable and subject to validation by the driver. They should use 2220 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific 2221 * changes and then applying them with %ETHTOOL_SLINKSETTINGS. 2222 * 2223 * Drivers that implement %get_link_ksettings and/or 2224 * %set_link_ksettings should ignore the @cmd 2225 * and @link_mode_masks_nwords fields (any change to them overwritten 2226 * by kernel), and rely only on kernel's internal 2227 * %__ETHTOOL_LINK_MODE_MASK_NBITS and 2228 * %ethtool_link_mode_mask_t. Drivers that implement 2229 * %set_link_ksettings() should validate all fields other than @cmd 2230 * and @link_mode_masks_nwords that are not described as read-only or 2231 * deprecated, and must ignore all fields described as read-only. 2232 * 2233 * @link_mode_masks is divided into three bitfields, each of length 2234 * @link_mode_masks_nwords: 2235 * - supported: Bitmap with each bit meaning given by 2236 * %ethtool_link_mode_bit_indices for the link modes, physical 2237 * connectors and other link features for which the interface 2238 * supports autonegotiation or auto-detection. Read-only. 2239 * - advertising: Bitmap with each bit meaning given by 2240 * %ethtool_link_mode_bit_indices for the link modes, physical 2241 * connectors and other link features that are advertised through 2242 * autonegotiation or enabled for auto-detection. 2243 * - lp_advertising: Bitmap with each bit meaning given by 2244 * %ethtool_link_mode_bit_indices for the link modes, and other 2245 * link features that the link partner advertised through 2246 * autonegotiation; 0 if unknown or not applicable.
