[ronnie sahlberg <ronniesahlberg@xxxxxxxxx>]

is IP the only protocol ever to be transported ato your dissector/protocol?

if so   you should just search for the IP handle  (see examples in  packet-vj.c)

ip_handle  = find_dissector("ip")
and then just call it through that handle.

...
call_dissector(ip_handle, ...


examples also available in packet-vj.c


if there are other protocols also possible in addition to ip   then
you will have
to create a dissector table and let ip and the others register with it.
in that case   grep for   register_dissector_table() and see how it is used.
