Noticed that we can shuffle the code around in fcoe_percpu_receive_thread a bit and avoid taking the fcoe_rx_list lock twice per iteration. This should improve throughput somewhat. With this change we take the lock, and check for new frames in a single critical section. Only if the list is empty do we drop the lock and re-acquire it after being signaled to wake up. Change Notes: v2) did some further cleanup on the patch by replacing the 2nd call of spin_lock/splice_init with a goto to the top of the outer loop. This allows me to change the inner while loop to an if conditional and remove the sencond check of kthread_should_stop. Based on suggestion from Vasu Dev.
