For 2505 * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user 2506 * (>= 0); on return, if handshake in progress, negative if 2507 * request size unsupported by kernel: absolute value indicates 2508 * kernel expected size and all the other fields but cmd 2509 * are 0; otherwise (handshake completed), strictly positive 2510 * to indicate size used by kernel and cmd field stays 2511 * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For 2512 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive 2513 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise 2514 * refused. For drivers: ignore this field (use kernel's 2515 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will 2516 * be overwritten by kernel. 2517 * @transceiver: Used to distinguish different possible PHY types, 2518 * reported consistently by PHYLIB. Read-only. 2519 * @master_slave_cfg: Master/slave port mode. 2520 * @master_slave_state: Master/slave port state. 2521 * @rate_matching: Rate adaptation performed by the PHY 2522 * @reserved: Reserved for future use; see the note on reserved space. 2523 * @link_mode_masks: Variable length bitmaps. 2524 * 2525 * If autonegotiation is disabled, the speed and @duplex represent the 2526 * fixed link mode and are writable if the driver supports multiple 2527 * link modes. If it is enabled then they are read-only; if the link 2528 * is up they represent the negotiated link mode; if the link is down, 2529 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and 2530 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. 2531 * 2532 * Some hardware interfaces may have multiple PHYs and/or physical 2533 * connectors fitted or do not allow the driver to detect which are 2534 * fitted. For these interfaces @port and/or @phy_address may be 2535 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. 2536 * Otherwise, attempts to write different values may be ignored or 2537 * rejected. 2538 * 2539 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt 2540 * are not available in %ethtool_link_settings. These fields will be 2541 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will 2542 * fail if any of them is set to non-zero value. 2543 * 2544 * Users should assume that all fields not marked read-only are 2545 * writable and subject to validation by the driver. They should use 2546 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific 2547 * changes and then applying them with %ETHTOOL_SLINKSETTINGS. 2548 * 2549 * Drivers that implement %get_link_ksettings and/or 2550 * %set_link_ksettings should ignore the @cmd 2551 * and @link_mode_masks_nwords fields (any change to them overwritten 2552 * by kernel), and rely only on kernel's internal 2553 * %__ETHTOOL_LINK_MODE_MASK_NBITS and 2554 * %ethtool_link_mode_mask_t. Drivers that implement 2555 * %set_link_ksettings() should validate all fields other than @cmd 2556 * and @link_mode_masks_nwords that are not described as read-only or 2557 * deprecated, and must ignore all fields described as read-only. 2558 * 2559 * @link_mode_masks is divided into three bitfields, each of length 2560 * @link_mode_masks_nwords: 2561 * - supported: Bitmap with each bit meaning given by 2562 * %ethtool_link_mode_bit_indices for the link modes, physical 2563 * connectors and other link features for which the interface 2564 * supports autonegotiation or auto-detection. Read-only. 2565 * - advertising: Bitmap with each bit meaning given by 2566 * %ethtool_link_mode_bit_indices for the link modes, physical 2567 * connectors and other link features that are advertised through 2568 * autonegotiation or enabled for auto-detection. 2569 * - lp_advertising: Bitmap with each bit meaning given by 2570 * %ethtool_link_mode_bit_indices for the link modes, and other 2571 * link features that the link partner advertised through 2572 * autonegotiation; 0 if unknown or not applicable.
