32 : : * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
33 : : * @supported: Bitmask of %SUPPORTED_* flags for the link modes,

35 : : * interface supports autonegotiation or auto-detection.
36 : : * Read-only.
37 : : * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
38 : : * physical connectors and other link features that are
39 : : * advertised through autonegotiation or enabled for
40 : : * auto-detection.
41 : : * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
42 : : * @duplex: Duplex mode; one of %DUPLEX_*
43 : : * @port: Physical connector type; one of %PORT_*
44 : : * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
45 : : * applicable. For clause 45 PHYs this is the PRTAD.
46 : : * @transceiver: Historically used to distinguish different possible
47 : : * PHY types, but not in a consistent way. Deprecated.
48 : : * @autoneg: Enable/disable autonegotiation and auto-detection;
49 : : * either %AUTONEG_DISABLE or %AUTONEG_ENABLE

55 : : * @maxrxpkt: Historically used to report RX IRQ coalescing; now
56 : : * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
57 : : * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
58 : : * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
59 : : * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
60 : : * value will be %ETH_TP_MDI_INVALID. Read-only.
61 : : * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
62 : : * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
63 : : * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
64 : : * When written successfully, the link should be renegotiated if
65 : : * necessary.
66 : : * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
67 : : * and other link features that the link partner advertised
68 : : * through autonegotiation; 0 if unknown or not applicable.
69 : : * Read-only.
70 : : *
71 : : * The link speed in Mbps is split between @speed and @speed_hi. Use
72 : : * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
73 : : * access it.
74 : : *
75 : : * If autonegotiation is disabled, the speed and @duplex represent the
76 : : * fixed link mode and are writable if the driver supports multiple
77 : : * link modes. If it is enabled then they are read-only; if the link
78 : : * is up they represent the negotiated link mode; if the link is down,
79 : : * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
80 : : * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
81 : : *
82 : : * Some hardware interfaces may have multiple PHYs and/or physical
83 : : * connectors fitted or do not allow the driver to detect which are
84 : : * fitted. For these interfaces @port and/or @phy_address may be
85 : : * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
86 : : * Otherwise, attempts to write different values may be ignored or
87 : : * rejected.
88 : : *
89 : : * Users should assume that all fields not marked read-only are
90 : : * writable and subject to validation by the driver. They should use
91 : : * %ETHTOOL_GSET to get the current values before making specific
92 : : * changes and then applying them with %ETHTOOL_SSET.
