172 * It is illegal to set both usecs and max_frames to zero as this
173 * would cause interrupts to never be generated. To disable
174 * coalescing, set usecs = 0 and max_frames = 1.
Ben Hutchings5f308d12011-08-15 14:06:20 +0000175 *
Ben Hutchingsa27fc962011-08-15 14:09:22 +0000176 * Some implementations ignore the value of max_frames and use the
177 * condition:
178 * time_since_first_completion >= usecs
179 * This is deprecated. Drivers for hardware that does not support
180 * counting completions should validate that max_frames == !rx_usecs.
181 *
Ben Hutchings5f308d12011-08-15 14:06:20 +0000182 * Adaptive RX/TX coalescing is an algorithm implemented by some
183 * drivers to improve latency under low packet rates and improve
184 * throughput under high packet rates. Some drivers only implement
185 * one of RX or TX adaptive coalescing. Anything not implemented by
186 * the driver causes these values to be silently ignored.
187 *
188 * When the packet rate is below @pkt_rate_high but above
189 * @pkt_rate_low (both measured in packets per second) the
190 * normal {rx,tx}_* coalescing parameters are used.
