Pascal,
Thanks for the feedback. I've converted to a builtin dissector.
I got stuck on adding the preference to handle the port number, I'll have to
take another stab at it tomorrow. The #defined port is the default for
Apache's Cassandra. I don't know what else in the world might use that port
as well. If defaulting to 0 is a better route I'm happy to accommodate.
