Change the sub-dissector handoff registration routines so that the
sub-dissector table is not stored in the header_field_info struct, but
in a separate namespace. Dissector tables are now registered by name
and not by field ID. For example:
udp_dissector_table = register_dissector_table("udp.port");
Because of this different namespace, dissector tables can have names
that are not field names. This is useful for ethertype, since multiple
fields are "ethertypes".
packet-ethertype.c replaces ethertype.c (the name was changed so that it
would be named in the same fashion as all the filenames passed to make-reg-dotc)
Although it registers no protocol or field, it registers one dissector table:
ethertype_dissector_table = register_dissector_table("ethertype");
All protocols that can be called because of an ethertype field now register
that fact with dissector_add() calls.
In this way, one dissector_table services all ethertype fields
(hf_eth_type, hf_llc_type, hf_null_etype, hf_vlan_etype)
Furthermore, the code allows for names of protocols to exist in the
etype_vals, yet a dissector for that protocol doesn't exist. The name
of the dissector is printed in COL_INFO. You're welcome, Richard. :-)
