Wireshark · Ethereal-dev: Re: [ethereal-dev] Binding multiple ports to one dissector

[David Frascone <dave@xxxxxxxxxxxx>]

Actually, I think doing it like I did it in packet-diameter.c is the wrong
way to do it.  Once several dissectors do this, the preferences dialog is
going to get un-wieldly.

I think a higher up package needs to create the tab, and different dissectors
need to add their ports to it.  Maybe packet-tcp and packet-udp?

Just my $.02 worth
