How is this tool tested beyond unit testing?
Can the assignee upload pcap files that contain Nack packets under different underlying protocols?
At least two Nack reasons plus reasonless Nack, and at least two underlying protocols should be included.
I confirm note-3 trace fulfills the requirements in note-2.
I notice that ndndump in ndn-tools:commit:589474aff39edb36b747e109d893e99187b41dc2 prints many lines of Tunnel Type: TCP, INCOMPLETE-PACKET, size: 0.
Correlating the timestamps in Wireshark, those packets are TCP ACKs without payload.
It's incorrect to label a TCP packet without payload as "INCOMPLETE" because there's no NDN packet at all; I suggest skipping them without printing anything.
Other than the above problem, Nacks are parsed correctly.
