S2io: Multiqueue network device support implementation
- Resubmit #3 Multiqueue netwrok device support implementation. - Added a loadable parameter "multiq" to enable/disable multiqueue support, by default it is disabled. - skb->queue_mapping is not used for queue/fifo selection. FIFO selection is based on skb->priority. - Added per FIFO flags FIFO_QUEUE_START and FIFO_QUEUE_STOP. Check this flag for starting and stopping netif queue and update the flags accordingly. - In tx_intr_handler added a check to ensure that we have free TXDs before wak- ing up the queue. - Added helper functions for queue manipulation(start/stop/wakeup) to invoke appropriate netif_ functions. - Calling netif_start/stop for link up/down case respectively. - As per Andi kleen's review comments, using skb->priority field for FIFO selection.
