Description

Currently, ndndump is able to recognize NDN packets on IPv4/IPv6 TCP tunnels only if an NDN packet is aligned to the front of a TCP segment.

If a TCP segment contains more than one NDN packets, all but the first NDN packet would be discarded.

If a NDN packet spans multiple TCP segments, it would be discarded, and "TLV length exceeds buffer length" error may appear.

ndndump should follow the TCP stream in the general case, and parse NDN packets in order.

In case of packet loss or reordering, a fallback heuristic of "looking for NDN packet aligned to the front of a TCP segment" can be used.
