207 | * (max_frames > 0 && completed_frames >= max_frames) | |
208 | * It is illegal to set both usecs and max_frames to zero as this | |
209 | * would cause interrupts to never be generated. To disable | |
210 | * coalescing, set usecs = 0 and max_frames = 1. | |
5f308d19 | 211 | * |
a27fc96b BH |
212 | * Some implementations ignore the value of max_frames and use the |
213 | * condition: | |
214 | * time_since_first_completion >= usecs | |
215 | * This is deprecated. Drivers for hardware that does not support | |
216 | * counting completions should validate that max_frames == !rx_usecs. | |
217 | * | |
5f308d19 BH |
218 | * Adaptive RX/TX coalescing is an algorithm implemented by some |
219 | * drivers to improve latency under low packet rates and improve | |
220 | * throughput under high packet rates. Some drivers only implement | |
221 | * one of RX or TX adaptive coalescing. Anything not implemented by | |
222 | * the driver causes these values to be silently ignored. | |
223 | * | |
224 | * When the packet rate is below @pkt_rate_high but above | |
225 | * @pkt_rate_low (both measured in packets per second) the | |
226 | * normal {rx,tx}_* coalescing parameters are used. | |
