For 1816 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive 1817 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise 1818 * refused. For drivers: ignore this field (use kernel's 1819 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will 1820 * be overwritten by kernel. 1821 * @supported: Bitmap with each bit meaning given by 1822 * %ethtool_link_mode_bit_indices for the link modes, physical 1823 * connectors and other link features for which the interface 1824 * supports autonegotiation or auto-detection. Read-only. 1825 * @advertising: Bitmap with each bit meaning given by 1826 * %ethtool_link_mode_bit_indices for the link modes, physical 1827 * connectors and other link features that are advertised through 1828 * autonegotiation or enabled for auto-detection. 1829 * @lp_advertising: Bitmap with each bit meaning given by 1830 * %ethtool_link_mode_bit_indices for the link modes, and other 1831 * link features that the link partner advertised through 1832 * autonegotiation; 0 if unknown or not applicable. Read-only. 1833 * @transceiver: Used to distinguish different possible PHY types, 1834 * reported consistently by PHYLIB. Read-only. 1835 * 1836 * If autonegotiation is disabled, the speed and @duplex represent the 1837 * fixed link mode and are writable if the driver supports multiple 1838 * link modes. If it is enabled then they are read-only; if the link 1839 * is up they represent the negotiated link mode; if the link is down, 1840 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and 1841 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. 1842 * 1843 * Some hardware interfaces may have multiple PHYs and/or physical 1844 * connectors fitted or do not allow the driver to detect which are 1845 * fitted. For these interfaces @port and/or @phy_address may be 1846 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. 1847 * Otherwise, attempts to write different values may be ignored or 1848 * rejected. 1849 * 1850 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt 1851 * are not available in %ethtool_link_settings. These fields will be 1852 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will 1853 * fail if any of them is set to non-zero value. 1854 * 1855 * Users should assume that all fields not marked read-only are 1856 * writable and subject to validation by the driver. They should use 1857 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific 1858 * changes and then applying them with %ETHTOOL_SLINKSETTINGS. 1859 * 1860 * Drivers that implement %get_link_ksettings and/or 1861 * %set_link_ksettings should ignore the @cmd 1862 * and @link_mode_masks_nwords fields (any change to them overwritten 1863 * by kernel), and rely only on kernel's internal 1864 * %__ETHTOOL_LINK_MODE_MASK_NBITS and 1865 * %ethtool_link_mode_mask_t. Drivers that implement 1866 * %set_link_ksettings() should validate all fields other than @cmd 1867 * and @link_mode_masks_nwords that are not described as read-only or 1868 * deprecated, and must ignore all fields described as read-only. 1869 */ 1870 struct ethtool_link_settings { 1871 uint32_t cmd; 1872 uint32_t speed; 1873 uint8_t duplex; 1874 uint8_t port; 1875 uint8_t phy_address; 1876 uint8_t autoneg; 1877 uint8_t mdio_support; 1878 uint8_t eth_tp_mdix; 1879 uint8_t eth_tp_mdix_ctrl; 1880 int8_t link_mode_masks_nwords; 1881 uint8_t transceiver; 1882 uint8_t reserved1[3]; 1883 uint32_t reserved[7]; 1884 uint32_t link_mode_masks[0]; 1885 /* layout of link_mode_masks fields: 1886 * uint32_t map_supported[link_mode_masks_nwords]; 1887 * uint32_t map_advertising[link_mode_masks_nwords]; 1888 * uint32_t map_lp_advertising[link_mode_masks_nwords]; 1889 */ 1890 }; 1891 #endif /* _LINUX_ETHTOOL_H */ 1892
