There's a DCB issue on x550. For 8 TCs, if a packet with user priority 6 or 7 is injected to the NIC, then the NIC will put 3 packets into the queue. There's also a similar issue for 4 TCs. The root cause is RXPBSIZE is not right. RXPBSIZE of x550 is 384. It's different from other 10G NICs. We need to set the RXPBSIZE according to the NIC type.
