  38 * struct ethtool_cmd - DEPRECATED, link control and status
  39 * This structure is DEPRECATED, please use struct ethtool_link_settings.
  40 * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
  41 * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
  42 *	physical connectors and other link features for which the
  43 *	interface supports autonegotiation or auto-detection.
  44 *	Read-only.
  45 * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
  46 *	physical connectors and other link features that are
  47 *	advertised through autonegotiation or enabled for
  48 *	auto-detection.
  49 * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
  50 * @duplex: Duplex mode; one of %DUPLEX_*
  51 * @port: Physical connector type; one of %PORT_*
  52 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
  53 *	applicable.  For clause 45 PHYs this is the PRTAD.
  54 * @transceiver: Historically used to distinguish different possible
  55 *	PHY types, but not in a consistent way.  Deprecated.
  56 * @autoneg: Enable/disable autonegotiation and auto-detection;
  57 *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
  58 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
  59 *	protocols supported by the interface; 0 if unknown.
  60 *	Read-only.
  61 * @maxtxpkt: Historically used to report TX IRQ coalescing; now
  62 *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
  63 * @maxrxpkt: Historically used to report RX IRQ coalescing; now
  64 *	obsoleted by &struct ethtool_coalesce.  Read-only; deprecated.
  65 * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
  66 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
  67 *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
  68 *	value will be %ETH_TP_MDI_INVALID.  Read-only.
  69 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
  70 *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
  71 *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
  72 *	When written successfully, the link should be renegotiated if
  73 *	necessary.
  74 * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
  75 *	and other link features that the link partner advertised
  76 *	through autonegotiation; 0 if unknown or not applicable.
  77 *	Read-only.
  78 * @reserved: Reserved for future use; see the note on reserved space.
  79 *
  80 * The link speed in Mbps is split between @speed and @speed_hi.  Use
  81 * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
  82 * access it.
  83 *
  84 * If autonegotiation is disabled, the speed and @duplex represent the
  85 * fixed link mode and are writable if the driver supports multiple
  86 * link modes.  If it is enabled then they are read-only; if the link
  87 * is up they represent the negotiated link mode; if the link is down,
  88 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
  89 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
  90 *
  91 * Some hardware interfaces may have multiple PHYs and/or physical
  92 * connectors fitted or do not allow the driver to detect which are
  93 * fitted.  For these interfaces @port and/or @phy_address may be
  94 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
  95 * Otherwise, attempts to write different values may be ignored or
  96 * rejected.
  97 *
  98 * Users should assume that all fields not marked read-only are
  99 * writable and subject to validation by the driver.  They should use
 100 * %ETHTOOL_GSET to get the current values before making specific
 101 * changes and then applying them with %ETHTOOL_SSET.
 102 *
 103 * Deprecated fields should be ignored by both users and drivers.

 453 * It is illegal to set both usecs and max_frames to zero as this

 463 * Adaptive RX/TX coalescing is an algorithm implemented by some
 464 * drivers to improve latency under low packet rates and improve

1435 * @rss_context: RSS context to be affected

1437 * @rule_locs: Array of used rule locations
1438 *
1439 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating

1442 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
1443 * act on.
1444 *

1451 * driver supports any special location values.  If that flag is not
1452 * set in @data then special location values should not be used.
1453 *

1461 * of the rule table, @rule_cnt is the number of defined rules, and

1463 * must use the second parameter to get_rxnfc() instead of @rule_locs.

1466 * @fs.@location either specifies the location to use or is a special
1467 * location value with %RX_CLS_LOC_SPECIAL flag set.  On return,
1468 * @fs.@location is the actual rule location.  If @fs.@flow_type
1469 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to

1788 * @fec: Bitmask of configured FEC modes.
1789 * @reserved: Reserved for future extensions, ignore on GET, write 0 for SET.
1790 *
1791 * Note that @reserved was never validated on input and ethtool user space
1792 * left it uninitialized when calling SET. Hence going forward it can only be
1793 * used to return a value to userspace with GET.
1794 *
1795 * FEC modes supported by the device can be read via %ETHTOOL_GLINKSETTINGS.
1796 * FEC settings are configured by link autonegotiation whenever it's enabled.
1797 * With autoneg on %ETHTOOL_GFECPARAM can be used to read the current mode.
1798 *
1799 * When autoneg is disabled %ETHTOOL_SFECPARAM controls the FEC settings.
1800 * It is recommended that drivers only accept a single bit set in @fec.
1801 * When multiple bits are set in @fec drivers may pick mode in an implementation
1802 * dependent way. Drivers should reject mixing %ETHTOOL_FEC_AUTO_BIT with other
1803 * FEC modes, because it's unclear whether in this case other modes constrain
1804 * AUTO or are independent choices.
1805 * Drivers must reject SET requests if they support none of the requested modes.
1806 *
1807 * If device does not support FEC drivers may use %ETHTOOL_FEC_NONE instead
1808 * of returning %EOPNOTSUPP from %ETHTOOL_GFECPARAM.

2445/**
2446 * struct ethtool_link_settings - link control and status
2447 *
2448 * IMPORTANT, Backward compatibility notice: When implementing new
2449 *	user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and
2450 *	if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
2451 *	settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
2452 *	succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
2453 *	that case.  Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
2454 *	%ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
2455 *	settings; do not use %ETHTOOL_SLINKSETTINGS if
2456 *	%ETHTOOL_GLINKSETTINGS failed: stick to
2457 *	%ETHTOOL_GSET/%ETHTOOL_SSET in that case.
2458 *
2459 * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
2460 * @speed: Link speed (Mbps)
2461 * @duplex: Duplex mode; one of %DUPLEX_*
2462 * @port: Physical connector type; one of %PORT_*
2463 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
2464 *	applicable.  For clause 45 PHYs this is the PRTAD.
2465 * @autoneg: Enable/disable autonegotiation and auto-detection;
2466 *	either %AUTONEG_DISABLE or %AUTONEG_ENABLE
2467 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
2468 *	protocols supported by the interface; 0 if unknown.
2469 *	Read-only.
2470 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
2471 *	%ETH_TP_MDI_*.  If the status is unknown or not applicable, the
2472 *	value will be %ETH_TP_MDI_INVALID.  Read-only.
2473 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2474 *	%ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
2475 *	yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2476 *	When written successfully, the link should be renegotiated if
2477 *	necessary.
2478 * @link_mode_masks_nwords: Number of 32-bit words for each of the
2479 *	supported, advertising, lp_advertising link mode bitmaps. For
2480 *	%ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2481 *	(>= 0); on return, if handshake in progress, negative if
2482 *	request size unsupported by kernel: absolute value indicates
2483 *	kernel expected size and all the other fields but cmd
2484 *	are 0; otherwise (handshake completed), strictly positive
2485 *	to indicate size used by kernel and cmd field stays
2486 *	%ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2487 *	%ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2488 *	value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2489 *	refused. For drivers: ignore this field (use kernel's
2490 *	__ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2491 *	be overwritten by kernel.
2492 * @transceiver: Used to distinguish different possible PHY types,
2493 *	reported consistently by PHYLIB.  Read-only.
2494 * @master_slave_cfg: Master/slave port mode.
2495 * @master_slave_state: Master/slave port state.
2496 * @rate_matching: Rate adaptation performed by the PHY
2497 * @reserved: Reserved for future use; see the note on reserved space.
2498 * @link_mode_masks: Variable length bitmaps.
2499 *
2500 * If autonegotiation is disabled, the speed and @duplex represent the
2501 * fixed link mode and are writable if the driver supports multiple
2502 * link modes.  If it is enabled then they are read-only; if the link
2503 * is up they represent the negotiated link mode; if the link is down,
2504 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2505 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2506 *
2507 * Some hardware interfaces may have multiple PHYs and/or physical
2508 * connectors fitted or do not allow the driver to detect which are
2509 * fitted.  For these interfaces @port and/or @phy_address may be
2510 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2511 * Otherwise, attempts to write different values may be ignored or
2512 * rejected.
2513 *
2514 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2515 * are not available in %ethtool_link_settings. These fields will be
2516 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2517 * fail if any of them is set to non-zero value.
2518 *
2519 * Users should assume that all fields not marked read-only are
2520 * writable and subject to validation by the driver.  They should use
2521 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2522 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2523 *
2524 * Drivers that implement %get_link_ksettings and/or
2525 * %set_link_ksettings should ignore the @cmd
2526 * and @link_mode_masks_nwords fields (any change to them overwritten
2527 * by kernel), and rely only on kernel's internal
2528 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2529 * %ethtool_link_mode_mask_t. Drivers that implement
2530 * %set_link_ksettings() should validate all fields other than @cmd
2531 * and @link_mode_masks_nwords that are not described as read-only or
2532 * deprecated, and must ignore all fields described as read-only.
2533 *
2534 * @link_mode_masks is divided into three bitfields, each of length
2535 * @link_mode_masks_nwords:
2536 * - supported: Bitmap with each bit meaning given by
2537 *	%ethtool_link_mode_bit_indices for the link modes, physical
2538 *	connectors and other link features for which the interface
2539 *	supports autonegotiation or auto-detection.  Read-only.
2540 * - advertising: Bitmap with each bit meaning given by
2541 *	%ethtool_link_mode_bit_indices for the link modes, physical
2542 *	connectors and other link features that are advertised through
2543 *	autonegotiation or enabled for auto-detection.
2544 * - lp_advertising: Bitmap with each bit meaning given by
2545 *	%ethtool_link_mode_bit_indices for the link modes, and other
2546 *	link features that the link partner advertised through
2547 *	autonegotiation; 0 if unknown or not applicable.  Read-only.
