Subject: dumpcap w/ pcapng produces out of order/negative times

While utilizing dumpcap with our app, we have observed the captured file
producing out of order timestamps to include negative times. We are still
investigating the root cause but believe it is in lib/pcapng. While doing
some testing of this issue, this behavior was not observed with pcap. In
the attached pcap, there are 5 streams (same curl multiple times a few
seconds apart), with streams 1 and 3 showing oddities. Specifically,
stream 1 is in the future relative to the packet order and stream 3 has a
negative time.
Not sure if the pcap file will actual post/attach, if it doesn't will try
something.
System: CentOS7 + devtoolset 9
