23/**
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.
