…ic-net#3731) Added python-libpcap to be used by arp_responder.py utility. This is needed to set conf.use_pcap which will make sure that L2pcapListenSocket uses libpcap instead of Linux PF_PACKET sockets. By using libpcap the vlan field will not be removed when the application receives the packet.

- What I did
Added python-libpcap to be used by arp_responder.py utility. This is needed to set conf.use_pcap which will make sure that L2pcapListenSocket uses libpcap instead of Linux PF_PACKET sockets. By using libpcap the vlan field will not be removed when the application receives the packet.
- How I did it
Added python-libpcap in docker-ptf Dockerfile.j2
- How to verify it
After setting conf.use_pcap = True
print the value of conf.L2listen
and the value is
<L2pcapListenSocket: read packets at layer 2 using libpcap>
Without the configuration the value printed would be
<L2ListenSocket: read packets at layer 2 using Linux PF_PACKET sockets>
