Hi!

When a client uses TCP pipelining (sending multiple queries over a persistent the TCP connection) and dsc restarts, the subsequent queries will not be counter, maybe due to missing TCP handshake.
I do not know if this is a real world problem yet. I was discovered while doint tests with https://github.com/Sinodun/dnsperf-tcp

Not surprising because dsc needs to track tcp connects in order to count them, the TCP code is up for a review/rework when time is available.

Major TCP code work/rework/updates is coming to pcap-thread thanks to DNS-OARC/dnscap#88 and DNS-OARC/dnscap#89.
