It seems tshark won't decode-as for syslog under tcp format, only udp, so this
required me change my syslog-ng.conf on both the client and server sides for
connectivity testing needs.

tshark -V -d udp.port==514,syslog

As per Balabit syslog-ng mailing list response: If that tshark problem happened
in a recent version it might be worth reporting a bug. As people come to depend
more and more on TCP Syslog due to reliability and TLS issues this will be an
important feature.
