So I should see if another dissector is registered, if so unregister
it, register my own, and then if I don't know how to handle the packet
pass it to the other dissector? Or am I looking in the wrong
direction? What is the right way to do it?
I would guess this is a quite common problem that you have IPv4 and
IPv6 versions of a protocol which use the same port, but different
messages. Is there a way in ethereal to register a protocol to
e.g. UDP(654) + IPv6 only?
