37/**
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.

1427 * %ETHTOOL_GRXCLSRLALL, %ETHTOOL_SRXCLSRLDEL or %ETHTOOL_SRXCLSRLINS
1428 * @flow_type: Type of flow to be affected, e.g. %TCP_V4_FLOW
1429 * @data: Command-dependent value
1430 * @fs: Flow classification rule
1431 * @rss_context: RSS context to be affected
1432 * @rule_cnt: Number of rules to be affected
1433 * @rule_locs: Array of used rule locations
1434 *
1435 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating
1436 * the fields included in the flow hash, e.g. %RXH_IP_SRC. The following
1437 * structure fields must not be used, except that if @flow_type includes
1438 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
1439 * act on.
1440 *
1441 * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
1442 * on return.
1443 *
1444 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined
1445 * rules on return. If @data is non-zero on return then it is the
1446 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
1447 * driver supports any special location values. If that flag is not
1448 * set in @data then special location values should not be used.
1449 *
1450 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an
1451 * existing rule on entry and @fs contains the rule on return; if
1452 * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is
1453 * filled with the RSS context ID associated with the rule.
1454 *
1455 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
1456 * user buffer for @rule_locs on entry. On return, @data is the size
1457 * of the rule table, @rule_cnt is the number of defined rules, and
1458 * @rule_locs contains the locations of the defined rules. Drivers
1459 * must use the second parameter to get_rxnfc() instead of @rule_locs.
1460 *
1461 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
1462 * @fs.@location either specifies the location to use or is a special
1463 * location value with %RX_CLS_LOC_SPECIAL flag set. On return,
1464 * @fs.@location is the actual rule location. If @fs.@flow_type
1465 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
1466 * use for flow spreading traffic which matches this rule. The value
1467 * from the rxfh indirection table will be added to @fs.@ring_cookie
1468 * to choose which ring to deliver to.

1478 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
1479 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable

2426 * @port: Physical connector type; one of %PORT_*
2427 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not

2429 * @autoneg: Enable/disable autonegotiation and auto-detection;
2430 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
2431 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
2432 * protocols supported by the interface; 0 if unknown.
2433 * Read-only.
2434 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
2435 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
2436 * value will be %ETH_TP_MDI_INVALID. Read-only.
2437 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2438 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
2439 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2440 * When written successfully, the link should be renegotiated if
2441 * necessary.
2442 * @link_mode_masks_nwords: Number of 32-bit words for each of the
2443 * supported, advertising, lp_advertising link mode bitmaps. For
2444 * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2445 * (>= 0); on return, if handshake in progress, negative if
2446 * request size unsupported by kernel: absolute value indicates
2447 * kernel expected size and all the other fields but cmd

2449 * to indicate size used by kernel and cmd field stays
2450 * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2451 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2452 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2453 * refused. For drivers: ignore this field (use kernel's
2454 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2455 * be overwritten by kernel.
2456 * @transceiver: Used to distinguish different possible PHY types,
2457 * reported consistently by PHYLIB. Read-only.
2458 * @master_slave_cfg: Master/slave port mode.
2459 * @master_slave_state: Master/slave port state.
2460 * @rate_matching: Rate adaptation performed by the PHY
2461 * @reserved: Reserved for future use; see the note on reserved space.
2462 * @link_mode_masks: Variable length bitmaps.
2463 *
2464 * If autonegotiation is disabled, the speed and @duplex represent the
2465 * fixed link mode and are writable if the driver supports multiple
2466 * link modes. If it is enabled then they are read-only; if the link
2467 * is up they represent the negotiated link mode; if the link is down,
2468 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2469 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2470 *
2471 * Some hardware interfaces may have multiple PHYs and/or physical
2472 * connectors fitted or do not allow the driver to detect which are
2473 * fitted. For these interfaces @port and/or @phy_address may be
2474 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2475 * Otherwise, attempts to write different values may be ignored or
2476 * rejected.
2477 *
2478 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2479 * are not available in %ethtool_link_settings. These fields will be
2480 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2481 * fail if any of them is set to non-zero value.
2482 *
2483 * Users should assume that all fields not marked read-only are
2484 * writable and subject to validation by the driver. They should use
2485 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2486 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2487 *
2488 * Drivers that implement %get_link_ksettings and/or
2489 * %set_link_ksettings should ignore the @cmd
2490 * and @link_mode_masks_nwords fields (any change to them overwritten
2491 * by kernel), and rely only on kernel's internal
2492 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2493 * %ethtool_link_mode_mask_t. Drivers that implement
2494 * %set_link_ksettings() should validate all fields other than @cmd
2495 * and @link_mode_masks_nwords that are not described as read-only or
2496 * deprecated, and must ignore all fields described as read-only.
2497 *
