Hi Team,

I am sending 1ad tagged traffic from external packet generator to ovs bridge interface(ingress-trunk). Receiving the same packet via ovs egress

port  in the Packet generator. I am using tcpdump to capture the packets on egress. But I am seeing TPID of received packets is miss-reported as 0x8100

Thomas F Herbert already mentioned that there is a bug in libpcap.

Could someone  please let me know , whether any alternate way to capture packets without any miss report or

Any solution exists.

Thanks & Regards,
