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.

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.

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.

68 * If autonegotiation is disabled, the speed and @duplex represent the
69 * fixed link mode and are writable if the driver supports multiple

73 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
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
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.

88 * other than @cmd that are not described as read-only or deprecated,

342 * @pkt_rate_high: Threshold for high packet rate (packets per second).
343 * @rx_coalesce_usecs_high: How many usecs to delay an RX interrupt after
344 * a packet arrives, when the packet rate is above @pkt_rate_high.
345 * @rx_max_coalesced_frames_high: Maximum number of packets to be received

352 * sampling, measured in seconds. Must not be zero.
354 * Each pair of (usecs, max_frames) fields specifies this exit
355 * condition for interrupt coalescing:
356 * (usecs > 0 && time_since_first_completion >= usecs) ||
357 * (max_frames > 0 && completed_frames >= max_frames)
358 * It is illegal to set both usecs and max_frames to zero as this
359 * would cause interrupts to never be generated. To disable
360 * coalescing, set usecs = 0 and max_frames = 1.
362 * Some implementations ignore the value of max_frames and use the
364 * time_since_first_completion >= usecs
365 * This is deprecated. Drivers for hardware that does not support
366 * counting completions should validate that max_frames == !rx_usecs.
368 * Adaptive RX/TX coalescing is an algorithm implemented by some
369 * drivers to improve latency under low packet rates and improve
370 * throughput under high packet rates. Some drivers only implement
371 * one of RX or TX adaptive coalescing. Anything not implemented by
372 * the driver causes these values to be silently ignored.
374 * When the packet rate is below @pkt_rate_high but above
375 * @pkt_rate_low (both measured in packets per second) the
376 * normal {rx,tx}_* coalescing parameters are used.

739 * A driver supporting the special location values for
740 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
741 * location, and may remove a rule at a later location (lower
742 * priority) that matches exactly the same set of flows. The special
743 * values are: %RX_CLS_LOC_ANY, selecting any location;
744 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
745 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable
746 * location (minimum priority). Additional special values may be
