Pcap trace support lives in two places these days: ethernet-input, and interface_output. Unless something is wrong, it should work on any interface type.
See https://fd.io/docs/vpp/master/gettingstarted/developers/vnet.html#pcap-rx-tx-and-drop-tracing N-tuple trace classification works as Ben described. It is not free. FWIW...

I do not think we support that today, however you can always use VPP pcap support: https://fd.io/docs/vpp/master/gettingstarted/developers/vnet.html#pcap-rx-tx-and-drop-tracing You can even attach filters to only dump packets from specific flows. I do not know how much it will impact your performance though, you'll need to experiment. Best ben
