You're right. The code in ethertype.c should be arranged into
a table similar to how packet-ipx.c. But both tables could be
changed so that the protocols that do have dissectors could be
called via the handoff routines (that is, dissector_add() is used
to register the dissector). Protocols that don't have dissectors
would simply have their name printed (that's what the packet-ipx.c
table called "ports" does).
