  36 * struct ethtool_cmd - DEPRECATED, link control and status
  37 * This structure is DEPRECATED, please use struct ethtool_link_settings.
  38 * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
  39 * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
  40 *	physical connectors and other link features for which the
  41 *	interface supports autonegotiation or auto-detection.
  42 *	Read-only.
  43 * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
  44 *	physical connectors and other link features that are
  45 *	advertised through autonegotiation or enabled for
  46 *	auto-detection.
  47 * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
  48 * @duplex: Duplex mode; one of %DUPLEX_*
  49 * @port: Physical connector type; one of %PORT_*
  50 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
  51 *	applicable.  For clause 45 PHYs this is the PRTAD.
  52 * @transceiver: Historically used to distinguish different possible
  53 *	PHY types, but not in a consistent way.  Deprecated.
  54 * @autoneg: Enable/disable autonegotiation and auto-detection;
  55 *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
  56 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
  57 *	protocols supported by the interface; 0 if unknown.
  58 *	Read-only.
  59 * @maxtxpkt: Historically used to report TX IRQ coalescing; now
  60 *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
  61 * @maxrxpkt: Historically used to report RX IRQ coalescing; now
  62 *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
  63 * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
  64 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
  65 *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
  66 *	value will be %ETH_TP_MDI_INVALID.  Read-only.
  67 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
  68 *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
  69 *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
  70 *	When written successfully, the link should be renegotiated if
  71 *	necessary.
  72 * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
  73 *	and other link features that the link partner advertised
  74 *	through autonegotiation; 0 if unknown or not applicable.
  75 *	Read-only.
  76 * @reserved: Reserved for future use; see the note on reserved space.
  77 *
  78 * The link speed in Mbps is split between @speed and @speed_hi.  Use
  79 * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
  80 * access it.
  81 *
  82 * If autonegotiation is disabled, the speed and @duplex represent the
  83 * fixed link mode and are writable if the driver supports multiple
  84 * link modes.  If it is enabled then they are read-only; if the link
  85 * is up they represent the negotiated link mode; if the link is down,
  86 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
  87 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
  88 *
  89 * Some hardware interfaces may have multiple PHYs and/or physical
  90 * connectors fitted or do not allow the driver to detect which are
  91 * fitted.  For these interfaces @port and/or @phy_address may be
  92 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
  93 * Otherwise, attempts to write different values may be ignored or
  94 * rejected.
  95 *
  96 * Users should assume that all fields not marked read-only are
  97 * writable and subject to validation by the driver.  They should use
  98 * %ETHTOOL_GSET to get the current values before making specific
  99 * changes and then applying them with %ETHTOOL_SSET.
 100 *
 101 * Deprecated fields should be ignored by both users and drivers.

1435 * @rule_locs: Array of used rule locations
1436 *
1437 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating

1440 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
1441 * act on.

1449 * driver supports any special location values.  If that flag is not
1450 * set in @data then special location values should not be used.

1465 * location value with %RX_CLS_LOC_SPECIAL flag set.  On return,
1466 * @fs.@location is the actual rule location.  If @fs.@flow_type
1467 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to

1786 * @fec: Bitmask of configured FEC modes.
1787 * @reserved: Reserved for future extensions, ignore on GET, write 0 for SET.
1788 *
1789 * Note that @reserved was never validated on input and ethtool user space
1790 * left it uninitialized when calling SET. Hence going forward it can only be
1791 * used to return a value to userspace with GET.
1792 *
1793 * FEC modes supported by the device can be read via %ETHTOOL_GLINKSETTINGS.
1794 * FEC settings are configured by link autonegotiation whenever it's enabled.
1795 * With autoneg on %ETHTOOL_GFECPARAM can be used to read the current mode.
1796 *
1797 * When autoneg is disabled %ETHTOOL_SFECPARAM controls the FEC settings.
1798 * It is recommended that drivers only accept a single bit set in @fec.
1799 * When multiple bits are set in @fec drivers may pick mode in an implementation
1800 * dependent way. Drivers should reject mixing %ETHTOOL_FEC_AUTO_BIT with other
1801 * FEC modes, because it's unclear whether in this case other modes constrain
1802 * AUTO or are independent choices.
1803 * Drivers must reject SET requests if they support none of the requested modes.
1804 *
1805 * If device does not support FEC drivers may use %ETHTOOL_FEC_NONE instead
1806 * of returning %EOPNOTSUPP from %ETHTOOL_GFECPARAM.

2437/**
2438 * struct ethtool_link_settings - link control and status
2439 *
2440 * IMPORTANT, Backward compatibility notice: When implementing new
2441 *	user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and
2442 *	if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
2443 *	settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
2444 *	succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
2445 *	that case.  Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
2446 *	%ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
2447 *	settings; do not use %ETHTOOL_SLINKSETTINGS if
2448 *	%ETHTOOL_GLINKSETTINGS failed: stick to
2449 *	%ETHTOOL_GSET/%ETHTOOL_SSET in that case.
2450 *
2451 * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
2452 * @speed: Link speed (Mbps)
2453 * @duplex: Duplex mode; one of %DUPLEX_*
2454 * @port: Physical connector type; one of %PORT_*
2455 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
2456 *	applicable.  For clause 45 PHYs this is the PRTAD.
2457 * @autoneg: Enable/disable autonegotiation and auto-detection;
2458 *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
2459 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
2460 *	protocols supported by the interface; 0 if unknown.
2461 *	Read-only.
2462 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
2463 *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
2464 *	value will be %ETH_TP_MDI_INVALID.  Read-only.
2465 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2466 *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
2467 *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2468 *	When written successfully, the link should be renegotiated if
2469 *	necessary.
2470 * @link_mode_masks_nwords: Number of 32-bit words for each of the
2471 *	supported, advertising, lp_advertising link mode bitmaps. For
2472 *	%ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2473 *	(>= 0); on return, if handshake in progress, negative if
2474 *	request size unsupported by kernel: absolute value indicates
2475 *	kernel expected size and all the other fields but cmd
2476 *	are 0; otherwise (handshake completed), strictly positive
2477 *	to indicate size used by kernel and cmd field stays
2478 *	%ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2479 *	%ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2480 *	value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2481 *	refused. For drivers: ignore this field (use kernel's
2482 *	__ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2483 *	be overwritten by kernel.
2484 * @transceiver: Used to distinguish different possible PHY types,
2485 *	reported consistently by PHYLIB.  Read-only.
2486 * @master_slave_cfg: Master/slave port mode.
2487 * @master_slave_state: Master/slave port state.
2488 * @rate_matching: Rate adaptation performed by the PHY
2489 * @reserved: Reserved for future use; see the note on reserved space.
2490 * @link_mode_masks: Variable length bitmaps.
2491 *
2492 * If autonegotiation is disabled, the speed and @duplex represent the
2493 * fixed link mode and are writable if the driver supports multiple
2494 * link modes.  If it is enabled then they are read-only; if the link
2495 * is up they represent the negotiated link mode; if the link is down,
2496 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2497 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2498 *
2499 * Some hardware interfaces may have multiple PHYs and/or physical
2500 * connectors fitted or do not allow the driver to detect which are
2501 * fitted.  For these interfaces @port and/or @phy_address may be
2502 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2503 * Otherwise, attempts to write different values may be ignored or
2504 * rejected.
2505 *
2506 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2507 * are not available in %ethtool_link_settings. These fields will be
2508 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2509 * fail if any of them is set to non-zero value.
2510 *
2511 * Users should assume that all fields not marked read-only are
2512 * writable and subject to validation by the driver.  They should use
2513 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2514 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2515 *
2516 * Drivers that implement %get_link_ksettings and/or
2517 * %set_link_ksettings should ignore the @cmd
2518 * and @link_mode_masks_nwords fields (any change to them overwritten
2519 * by kernel), and rely only on kernel's internal
2520 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2521 * %ethtool_link_mode_mask_t. Drivers that implement
2522 * %set_link_ksettings() should validate all fields other than @cmd
2523 * and @link_mode_masks_nwords that are not described as read-only or
2524 * deprecated, and must ignore all fields described as read-only.
2525 *
2526 * @link_mode_masks is divided into three bitfields, each of length
2527 * @link_mode_masks_nwords:
2528 * - supported: Bitmap with each bit meaning given by
2529 *	%ethtool_link_mode_bit_indices for the link modes, physical
2530 *	connectors and other link features for which the interface
2531 *	supports autonegotiation or auto-detection.  Read-only.
2532 * - advertising: Bitmap with each bit meaning given by
2533 *	%ethtool_link_mode_bit_indices for the link modes, physical
2534 *	connectors and other link features that are advertised through
2535 *	autonegotiation or enabled for auto-detection.
2536 * - lp_advertising: Bitmap with each bit meaning given by
2537 *	%ethtool_link_mode_bit_indices for the link modes, and other
2538 *	link features that the link partner advertised through
2539 *	autonegotiation; 0 if unknown or not applicable.  Read-only.
