There is potentially lots of contention for the rx_list_lock. On a cpu that is receiving lots of fcoe traffic, the softirq context has to add and release the lock for every frame it receives, as does the receiving per-cpu thread. We can reduce this contention somewhat by altering the per-cpu threads loop such that when traffic is detected on the fcoe_rx_list, we splice it to a temporary list. In this way, we can process multiple skbs while only having to acquire and release the fcoe_rx_list lock once.
