Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/6483
to look at the new patch set (#2).
ttcn3-tcpdump-stop.sh: Wait to receive last packets before stopping tcpdump
There's a time delay between packets are sent through the system and
tcpdump reads, buffers and stores them into the pcap file. We need to
give it more time to process everything before killing it, otherwise
last (or all) packets from the test are not captured.
