42 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE

53 * value will be %ETH_TP_MDI_INVALID. Read-only.
54 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of

382 * should be coalesced until
383 * (usecs > 0 && time_since_first_completion >= usecs) ||
384 * (max_frames > 0 && completed_frames >= max_frames)
386 * It is illegal to set both usecs and max_frames to zero as this
387 * would cause interrupts to never be generated. To disable
388 * coalescing, set usecs = 0 and max_frames = 1.
390 * Some implementations ignore the value of max_frames and use the
391 * condition time_since_first_completion >= usecs
393 * This is deprecated. Drivers for hardware that does not support
394 * counting completions should validate that max_frames == !rx_usecs.
396 * Adaptive RX/TX coalescing is an algorithm implemented by some
397 * drivers to improve latency under low packet rates and improve
398 * throughput under high packet rates. Some drivers only implement
399 * one of RX or TX adaptive coalescing. Anything not implemented by
400 * the driver causes these values to be silently ignored.
402 * When the packet rate is below @pkt_rate_high but above
403 * @pkt_rate_low (both measured in packets per second) the
404 * normal {rx,tx}_* coalescing parameters are used.
