The CNP CoS queue is reserved for internal RDMA Congestion Notification Packets (CNP) and should not be used for a TC. Modify the CoS queue discovery code to skip over the CNP CoS queue and to reduce bp->max_tc accordingly. However, if RDMA is disabled in NVRAM, the the CNP CoS queue can be used for a TC.
