The firmware shall timeout an outstanding mailbox IOCB in 2 * R_A_TOV (in
tenths of a second) after it hits the wire.  But, if there are any request
resource contraints (i.e. during heavy I/O), exchanges can be held off for
at most R_A_TOV.  Therefore, the driver will wait 4 * R_A_TOV before
scheduling a recovery (big hammer).
