209 * statistics block updates. Some drivers do not have an

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

232 * @rate_sample_interval: How often to do adaptive coalescing packet rate
233 * sampling, measured in seconds. Must not be zero.
235 * Each pair of (usecs, max_frames) fields specifies this exit
236 * condition for interrupt coalescing:
237 * (usecs > 0 && time_since_first_completion >= usecs) ||
238 * (max_frames > 0 && completed_frames >= max_frames)
239 * It is illegal to set both usecs and max_frames to zero as this
240 * would cause interrupts to never be generated. To disable
241 * coalescing, set usecs = 0 and max_frames = 1.
243 * Some implementations ignore the value of max_frames and use the
245 * time_since_first_completion >= usecs
246 * This is deprecated. Drivers for hardware that does not support
247 * counting completions should validate that max_frames == !rx_usecs.
249 * Adaptive RX/TX coalescing is an algorithm implemented by some
250 * drivers to improve latency under low packet rates and improve
251 * throughput under high packet rates. Some drivers only implement
252 * one of RX or TX adaptive coalescing. Anything not implemented by
253 * the driver causes these values to be silently ignored.
255 * When the packet rate is below @pkt_rate_high but above
256 * @pkt_rate_low (both measured in packets per second) the
257 * normal {rx,tx}_* coalescing parameters are used.
