make test: work around scapy truncated packets
Under stress, it's possible to hit a race condition, when the packet header is fully written to pcap, but not all packet data - yet. Scapy is stupid enough to: 1. not detect and report this error, truncating the packet instead 2. continue munching more data from wrong offset The work around is to scan the file ahead, parse the packet header, figure out how much data we need, wait for the file to be big enough, then restore the file position back to where it was and finally let scapy parse the packet.
