Will take a look in the next week. Thanks for the comments, I didn't see any
emails for these or I would have gotten them done already.
I went with heur simply because the example ethertype method resulted in the
eth dissector processing the ethernet addresses and forwarding the remainder of
the frame to my dissector. I wanted this dissector to process the hierarchical
MAC addresses and the tag both and then to forward the remainder of the packet
back to the eth dissector. Is it possible to do this without using the
heur_dissector? When I searched around for a way to do this, the only
recommendation I found was to do what I've done.
Thanks,
Leonard
