+ * @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

+ * @tx_max_coalesced_frames_high: Maximum number of packets to be sent before
+ *      a TX 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.
