* @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

* @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.

*
* 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.
