For 1741*d3b7b374SJason Baron * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive 1742*d3b7b374SJason Baron * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise 1743*d3b7b374SJason Baron * refused. For drivers: ignore this field (use kernel's 1744*d3b7b374SJason Baron * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will 1745*d3b7b374SJason Baron * be overwritten by kernel. 1746*d3b7b374SJason Baron * @supported: Bitmap with each bit meaning given by 1747*d3b7b374SJason Baron * %ethtool_link_mode_bit_indices for the link modes, physical 1748*d3b7b374SJason Baron * connectors and other link features for which the interface 1749*d3b7b374SJason Baron * supports autonegotiation or auto-detection. Read-only. 1750*d3b7b374SJason Baron * @advertising: Bitmap with each bit meaning given by 1751*d3b7b374SJason Baron * %ethtool_link_mode_bit_indices for the link modes, physical 1752*d3b7b374SJason Baron * connectors and other link features that are advertised through 1753*d3b7b374SJason Baron * autonegotiation or enabled for auto-detection. 1754*d3b7b374SJason Baron * @lp_advertising: Bitmap with each bit meaning given by 1755*d3b7b374SJason Baron * %ethtool_link_mode_bit_indices for the link modes, and other 1756*d3b7b374SJason Baron * link features that the link partner advertised through 1757*d3b7b374SJason Baron * autonegotiation; 0 if unknown or not applicable. Read-only. 1758*d3b7b374SJason Baron * @transceiver: Used to distinguish different possible PHY types, 1759*d3b7b374SJason Baron * reported consistently by PHYLIB. Read-only. 1760*d3b7b374SJason Baron * 1761*d3b7b374SJason Baron * If autonegotiation is disabled, the speed and @duplex represent the 1762*d3b7b374SJason Baron * fixed link mode and are writable if the driver supports multiple 1763*d3b7b374SJason Baron * link modes. If it is enabled then they are read-only; if the link 1764*d3b7b374SJason Baron * is up they represent the negotiated link mode; if the link is down, 1765*d3b7b374SJason Baron * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and 1766*d3b7b374SJason Baron * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. 1767*d3b7b374SJason Baron * 1768*d3b7b374SJason Baron * Some hardware interfaces may have multiple PHYs and/or physical 1769*d3b7b374SJason Baron * connectors fitted or do not allow the driver to detect which are 1770*d3b7b374SJason Baron * fitted. For these interfaces @port and/or @phy_address may be 1771*d3b7b374SJason Baron * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. 1772*d3b7b374SJason Baron * Otherwise, attempts to write different values may be ignored or 1773*d3b7b374SJason Baron * rejected. 1774*d3b7b374SJason Baron * 1775*d3b7b374SJason Baron * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt 1776*d3b7b374SJason Baron * are not available in %ethtool_link_settings. Until all drivers are 1777*d3b7b374SJason Baron * converted to ignore them or to the new %ethtool_link_settings API, 1778*d3b7b374SJason Baron * for both queries and changes, users should always try 1779*d3b7b374SJason Baron * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick 1780*d3b7b374SJason Baron * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it 1781*d3b7b374SJason Baron * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and 1782*d3b7b374SJason Baron * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing 1783*d3b7b374SJason Baron * either %ethtool_cmd or %ethtool_link_settings). 1784*d3b7b374SJason Baron * 1785*d3b7b374SJason Baron * Users should assume that all fields not marked read-only are 1786*d3b7b374SJason Baron * writable and subject to validation by the driver. They should use 1787*d3b7b374SJason Baron * %ETHTOOL_GLINKSETTINGS to get the current values before making specific 1788*d3b7b374SJason Baron * changes and then applying them with %ETHTOOL_SLINKSETTINGS. 1789*d3b7b374SJason Baron * 1790*d3b7b374SJason Baron * Drivers that implement %get_link_ksettings and/or 1791*d3b7b374SJason Baron * %set_link_ksettings should ignore the @cmd 1792*d3b7b374SJason Baron * and @link_mode_masks_nwords fields (any change to them overwritten 1793*d3b7b374SJason Baron * by kernel), and rely only on kernel's internal 1794*d3b7b374SJason Baron * %__ETHTOOL_LINK_MODE_MASK_NBITS and 1795*d3b7b374SJason Baron * %ethtool_link_mode_mask_t.
