385 * queue has this number, set the inapplicable fields to ~0 and return 0.
386 * Returns a negative error code or zero.
387 * @set_per_queue_coalesce: Set interrupt coalescing parameters per queue.
388 * It must check that the given queue number is valid. If neither a RX nor

407 * cannot use the standard PHY library helpers.
408 *
409 * All operations are optional (i.e. the function pointer may be set
410 * to %NULL) and callers must take this into account. Callers must
