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