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.

1425 * %ETHTOOL_GRXCLSRLALL, %ETHTOOL_SRXCLSRLDEL or %ETHTOOL_SRXCLSRLINS
1426 * @flow_type: Type of flow to be affected, e.g. %TCP_V4_FLOW
1427 * @data: Command-dependent value
1428 * @fs: Flow classification rule
1429 * @rss_context: RSS context to be affected
1430 * @rule_cnt: Number of rules to be affected
1431 * @rule_locs: Array of used rule locations
1432 *
1433 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating
1434 * the fields included in the flow hash, e.g. %RXH_IP_SRC. The following
1435 * structure fields must not be used, except that if @flow_type includes
1436 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
1437 * act on.
1438 *
1439 * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
1440 * on return.
1441 *
1442 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined
1443 * rules on return. If @data is non-zero on return then it is the
1444 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
1445 * driver supports any special location values. If that flag is not
1446 * set in @data then special location values should not be used.
1447 *
1448 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an
1449 * existing rule on entry and @fs contains the rule on return; if
1450 * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is
1451 * filled with the RSS context ID associated with the rule.
1452 *
1453 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
1454 * user buffer for @rule_locs on entry. On return, @data is the size
1455 * of the rule table, @rule_cnt is the number of defined rules, and
1456 * @rule_locs contains the locations of the defined rules. Drivers
1457 * must use the second parameter to get_rxnfc() instead of @rule_locs.
1458 *
1459 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
1460 * @fs.@location either specifies the location to use or is a special
1461 * location value with %RX_CLS_LOC_SPECIAL flag set. On return,
1462 * @fs.@location is the actual rule location. If @fs.@flow_type
1463 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
1464 * use for flow spreading traffic which matches this rule. The value
1465 * from the rxfh indirection table will be added to @fs.@ring_cookie
1466 * to choose which ring to deliver to.
1467 *
1468 * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
1469 * existing rule on entry.
1470 *
1471 * A driver supporting the special location values for
1472 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
1473 * location, and may remove a rule at a later location (lower
1474 * priority) that matches exactly the same set of flows. The special
1475 * values are %RX_CLS_LOC_ANY, selecting any location;
1476 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
1477 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable
1478 * location (minimum priority). Additional special values may be

2451 * refused. For drivers: ignore this field (use kernel's
2452 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2453 * be overwritten by kernel.
2454 * @transceiver: Used to distinguish different possible PHY types,
2455 * reported consistently by PHYLIB. Read-only.
2456 * @master_slave_cfg: Master/slave port mode.
2457 * @master_slave_state: Master/slave port state.
2458 * @rate_matching: Rate adaptation performed by the PHY
2459 * @reserved: Reserved for future use; see the note on reserved space.
2460 * @link_mode_masks: Variable length bitmaps.
2461 *
2462 * If autonegotiation is disabled, the speed and @duplex represent the
2463 * fixed link mode and are writable if the driver supports multiple
2464 * link modes. If it is enabled then they are read-only; if the link
2465 * is up they represent the negotiated link mode; if the link is down,
2466 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2467 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2468 *
2469 * Some hardware interfaces may have multiple PHYs and/or physical

2494 * deprecated, and must ignore all fields described as read-only.
