Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable.
