   * @tx_coalesce_usecs: How many usecs to delay a TX interrupt after

   *	a packet is sent.

   * @tx_max_coalesced_frames: Maximum number of packets to be sent

   *	before a TX interrupt.

   * @tx_coalesce_usecs_irq: Same as @tx_coalesce_usecs, except that
   *	this value applies while an IRQ is being serviced by the host.
   * @tx_max_coalesced_frames_irq: Same as @tx_max_coalesced_frames,
   *	except that this value applies while an IRQ is being serviced
   *	by the host.
   * @stats_block_coalesce_usecs: How many usecs to delay in-memory
   *	statistics block updates.  Some drivers do not have an
   *	in-memory statistic block, and in such cases this value is
   *	ignored.  This value must not be zero.
   * @use_adaptive_rx_coalesce: Enable adaptive RX coalescing.
   * @use_adaptive_tx_coalesce: Enable adaptive TX coalescing.
   * @pkt_rate_low: Threshold for low packet rate (packets per second).

   *	a packet arrives, when the packet rate is below @pkt_rate_low.

   * @rx_max_coalesced_frames_low: Maximum number of packets to be received
   *	before an RX interrupt, when the packet rate is below @pkt_rate_low.

   * @tx_coalesce_usecs_low: How many usecs to delay a TX interrupt after
   *	a packet is sent, when the packet rate is below @pkt_rate_low.

   * @tx_max_coalesced_frames_low: Maximum nuumber of packets to be sent before
   *	a TX interrupt, when the packet rate is below @pkt_rate_low.

   * @pkt_rate_high: Threshold for high packet rate (packets per second).
   * @rx_coalesce_usecs_high: How many usecs to delay an RX interrupt after
   *	a packet arrives, when the packet rate is above @pkt_rate_high.

   * @rx_max_coalesced_frames_high: Maximum number of packets to be received
   *	before an RX interrupt, when the packet rate is above @pkt_rate_high.

   * @rate_sample_interval: How often to do adaptive coalescing packet rate
   *	sampling, measured in seconds.  Must not be zero.
   *

   * Each pair of (usecs, max_frames) fields specifies this exit
   * condition for interrupt coalescing:
   *	(usecs > 0 && time_since_first_completion >= usecs) ||
   *	(max_frames > 0 && completed_frames >= max_frames)
   * It is illegal to set both usecs and max_frames to zero as this
   * would cause interrupts to never be generated.  To disable
   * coalescing, set usecs = 0 and max_frames = 1.

   *

   * Some implementations ignore the value of max_frames and use the
   * condition:
   *	time_since_first_completion >= usecs
   * This is deprecated.  Drivers for hardware that does not support
   * counting completions should validate that max_frames == !rx_usecs.
   *

   * Adaptive RX/TX coalescing is an algorithm implemented by some
   * drivers to improve latency under low packet rates and improve
   * throughput under high packet rates.  Some drivers only implement
   * one of RX or TX adaptive coalescing.  Anything not implemented by
   * the driver causes these values to be silently ignored.
   *
   * When the packet rate is below @pkt_rate_high but above
   * @pkt_rate_low (both measured in packets per second) the
   * normal {rx,tx}_* coalescing parameters are used.

   * @get_regs: Get device registers

   * @get_eeprom: Read data from the device EEPROM.

   *	Should fill in the magic field.  Don't need to check len for zero
   *	or wraparound.  Fill in the data argument with the eeprom values
   *	from offset to offset + len.  Update len to the amount read.

   *	the indicator accordingly.  Finally, it is called with the argument
   *	%ETHTOOL_ID_INACTIVE and must deactivate the indicator.  Returns a
   *	negative error code or zero.

   * @get_ethtool_stats: Return extended statistics about the device.
   *	This is only useful if the device maintains statistics not
   *	included in &struct rtnl_link_stats64.
   * @begin: Function to be called before any other operation.  Returns a

   *	Returns a negative error code or zero.
   * @reset: Reset (part of) the device, as specified by a bitmask of
   *	flags from &enum ethtool_reset_flags.  Returns a negative
