# Then on board B, we can get a frame without sequence tags from board A.
# Connect eth5 of board A with eth5 of board B.
# On board B:
tsntool> cbrec --device eth5 --index 1 --seq_len 16 --his_len 31 --rtag_pop_en
tcpdump -i eth2 -w eth2.pcap
# On board A:
ping 192.168.0.2
# On board B, we can get only one frame without sequence tag, another frame from eth4 or eth5 is dropped.
