be2net: Add MCC queue mechanism for BE cmds
Currenlty all cmds use the blocking MCC mbox to post cmds. An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable to disable BHs while a blocking mbox cmd is in progress (and take long to finish.) This can lockup a cmd in progress in process context. Instead cmds that may be called in BH context must use the MCC queue to post cmds. The cmd completions are rcvd in a separate completion queue and the events are placed in the tx-event queue. Signed-off-by: Sathya Perla <sathyap@serverengines.com> Signed-off-by: David S.
