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

1451 * @rss_context: RSS context to be affected
1452 * @rule_cnt: Number of rules to be affected
1453 * @rule_locs: Array of used rule locations
1454 *
1455 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating

1457 * structure fields must not be used, except that if @flow_type includes
1458 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
1459 * act on.
1460 *
1461 * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
1462 * on return.
1463 *
1464 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined

1466 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
1467 * driver supports any special location values. If that flag is not
1468 * set in @data then special location values should not be used.
1469 *
1470 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an

1474 *
1475 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the

1477 * of the rule table, @rule_cnt is the number of defined rules, and
1478 * @rule_locs contains the locations of the defined rules. Drivers
1479 * must use the second parameter to get_rxnfc() instead of @rule_locs.
1480 *

1482 * @fs.@location either specifies the location to use or is a special
1483 * location value with %RX_CLS_LOC_SPECIAL flag set. On return,
1484 * @fs.@location is the actual rule location. If @fs.@flow_type
1485 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
1486 * use for flow spreading traffic which matches this rule. The value
1487 * from the rxfh indirection table will be added to @fs.@ring_cookie

2494 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
2495 * value will be %ETH_TP_MDI_INVALID. Read-only.
2496 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2497 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
2498 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2499 * When written successfully, the link should be renegotiated if
2500 * necessary.
2501 * @link_mode_masks_nwords: Number of 32-bit words for each of the
2502 * supported, advertising, lp_advertising link mode bitmaps. For
2503 * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2504 * (>= 0); on return, if handshake in progress, negative if
2505 * request size unsupported by kernel: absolute value indicates
2506 * kernel expected size and all the other fields but cmd
2507 * are 0; otherwise (handshake completed), strictly positive
2508 * to indicate size used by kernel and cmd field stays
2509 * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2510 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2511 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2512 * refused. For drivers: ignore this field (use kernel's
2513 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2514 * be overwritten by kernel.
2515 * @transceiver: Used to distinguish different possible PHY types,
2516 * reported consistently by PHYLIB. Read-only.
2517 * @master_slave_cfg: Master/slave port mode.
2518 * @master_slave_state: Master/slave port state.
2519 * @rate_matching: Rate adaptation performed by the PHY
2520 * @reserved: Reserved for future use; see the note on reserved space.
2521 * @link_mode_masks: Variable length bitmaps.
2522 *
2523 * If autonegotiation is disabled, the speed and @duplex represent the
2524 * fixed link mode and are writable if the driver supports multiple
2525 * link modes. If it is enabled then they are read-only; if the link
2526 * is up they represent the negotiated link mode; if the link is down,
2527 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2528 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2529 *
2530 * Some hardware interfaces may have multiple PHYs and/or physical
2531 * connectors fitted or do not allow the driver to detect which are
2532 * fitted. For these interfaces @port and/or @phy_address may be
2533 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2534 * Otherwise, attempts to write different values may be ignored or
2535 * rejected.
2536 *
2537 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2538 * are not available in %ethtool_link_settings. These fields will be
2539 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2540 * fail if any of them is set to non-zero value.
2541 *
2542 * Users should assume that all fields not marked read-only are
2543 * writable and subject to validation by the driver. They should use
2544 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2545 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2546 *
2547 * Drivers that implement %get_link_ksettings and/or
2548 * %set_link_ksettings should ignore the @cmd
2549 * and @link_mode_masks_nwords fields (any change to them overwritten
2550 * by kernel), and rely only on kernel's internal
2551 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2552 * %ethtool_link_mode_mask_t. Drivers that implement
2553 * %set_link_ksettings() should validate all fields other than @cmd
2554 * and @link_mode_masks_nwords that are not described as read-only or
2555 * deprecated, and must ignore all fields described as read-only.
2556 *
2557 * @link_mode_masks is divided into three bitfields, each of length
2558 * @link_mode_masks_nwords:
2559 * - supported: Bitmap with each bit meaning given by
2560 * %ethtool_link_mode_bit_indices for the link modes, physical
2561 * connectors and other link features for which the interface
2562 * supports autonegotiation or auto-detection. Read-only.
2563 * - advertising: Bitmap with each bit meaning given by
2564 * %ethtool_link_mode_bit_indices for the link modes, physical
2565 * connectors and other link features that are advertised through
2566 * autonegotiation or enabled for auto-detection.
2567 * - lp_advertising: Bitmap with each bit meaning given by
2568 * %ethtool_link_mode_bit_indices for the link modes, and other
2569 * link features that the link partner advertised through
2570 * autonegotiation; 0 if unknown or not applicable. Read-only.
