543 * a TX queue has this number, return -EINVAL. If only a RX queue or a TX
544 * queue has this number, set the inapplicable fields to ~0 and return 0.
545 * Returns a negative error code or zero.
546 * @set_per_queue_coalesce: Set interrupt coalescing parameters per queue.
547 * It must check that the given queue number is valid. If neither a RX nor
548 * a TX queue has this number, return -EINVAL. If only a RX queue or a TX
549 * queue has this number, ignore the inapplicable fields. Supported
550 * coalescing types should be set in @supported_coalesce_params.
551 * Returns a negative error code or zero.
552 * @get_link_ksettings: Get various device settings including Ethernet link
553 * settings. The %cmd and %link_mode_masks_nwords fields should be
554 * ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter),
555 * any change to them will be overwritten by kernel. Returns a negative
556 * error code or zero.
557 * @set_link_ksettings: Set various device settings including Ethernet link
558 * settings. The %cmd and %link_mode_masks_nwords fields should be
559 * ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter),
560 * any change to them will be overwritten by kernel. Returns a negative
561 * error code or zero.
562 * @get_fec_stats: Report FEC statistics.
563 * Core will sum up per-lane stats to get the total.
564 * Drivers must not zero statistics which they don't report. The stats
565 * structure is initialized to ETHTOOL_STAT_NOT_SET indicating driver does
566 * not report statistics.
567 * @get_fecparam: Get the network device Forward Error Correction parameters.
568 * @set_fecparam: Set the network device Forward Error Correction parameters.
569 * @get_ethtool_phy_stats: Return extended statistics about the PHY device.
570 * This is only useful if the device maintains PHY statistics and
571 * cannot use the standard PHY library helpers.
572 * @get_phy_tunable: Read the value of a PHY tunable.
573 * @set_phy_tunable: Set the value of a PHY tunable.
574 * @get_module_eeprom_by_page: Get a region of plug-in module EEPROM data from
575 * specified page. Returns a negative error code or the amount of bytes
577 * @get_eth_phy_stats: Query some of the IEEE 802.3 PHY statistics.
578 * @get_eth_mac_stats: Query some of the IEEE 802.3 MAC statistics.
579 * @get_eth_ctrl_stats: Query some of the IEEE 802.3 MAC Ctrl statistics.
580 * @get_rmon_stats: Query some of the RMON (RFC 2819) statistics.
581 * Set %ranges to a pointer to zero-terminated array of byte ranges.
583 * All operations are optional (i.e. the function pointer may be set
584 * to %NULL) and callers must take this into account. Callers must
585 * hold the RTNL lock.
587 * See the structures used by these operations for further documentation.
588 * Note that for all operations using a structure ending with a zero-
589 * length array, the array is allocated separately in the kernel and
590 * is passed to the driver as an additional parameter.
592 * See &struct net_device and &struct net_device_ops for documentation
593 * of the generic netdev features interface.
