If it 1808 * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and 1809 * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing 1810 * either %ethtool_cmd or %ethtool_link_settings). 1811 * 1812 * Users should assume that all fields not marked read-only are 1813 * writable and subject to validation by the driver. They should use 1814 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific 1815 * changes and then applying them with %ETHTOOL_SLINKSETTINGS. 1816 * 1817 * Drivers that implement %get_link_ksettings and/or 1818 * %set_link_ksettings should ignore the @cmd 1819 * and @link_mode_masks_nwords fields (any change to them overwritten 1820 * by kernel), and rely only on kernel's internal 1821 * %__ETHTOOL_LINK_MODE_MASK_NBITS and 1822 * %ethtool_link_mode_mask_t. Drivers that implement 1823 * %set_link_ksettings() should validate all fields other than @cmd 1824 * and @link_mode_masks_nwords that are not described as read-only or 1825 * deprecated, and must ignore all fields described as read-only. 1826 */ 1827 struct ethtool_link_settings { 1828 uint32_t cmd; 1829 uint32_t speed; 1830 uint8_t duplex; 1831 uint8_t port; 1832 uint8_t phy_address; 1833 uint8_t autoneg; 1834 uint8_t mdio_support; 1835 uint8_t eth_tp_mdix; 1836 uint8_t eth_tp_mdix_ctrl; 1837 int8_t link_mode_masks_nwords; 1838 uint8_t transceiver; 1839 uint8_t reserved1[3]; 1840 uint32_t reserved[7]; 1841 uint32_t link_mode_masks[0]; 1842 /* layout of link_mode_masks fields: 1843 * uint32_t map_supported[link_mode_masks_nwords]; 1844 * uint32_t map_advertising[link_mode_masks_nwords]; 1845 * uint32_t map_lp_advertising[link_mode_masks_nwords]; 1846 */ 1847 }; 1848 #endif /* _LINUX_ETHTOOL_H */ 1849
