325 * @begin: Function to be called before any other operation. Returns a

355 * hash key, and/or hash function assiciated to the given rss context.

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

403 * cannot use the standard PHY library helpers.
404 *
405 * All operations are optional (i.e. the function pointer may be set
