NLPID's of 0x08 and 0x09 should be labeled as Q.933 and LMI,
respectively, not Q.931 and Q.2931, in Frame Relay.
When dissecting Q.933-style multiprotocol encapsulated Frame Relay
frames, use the "osinl" dissector table to check for OSI network layer
protocols, include the NLPID in the tvbuff you hand to
"dissector_try_port()" with that dissector table, and put the NLPID into
the protocol tree as an invisible item - the NLPID is considered part of
the PDU for those protocols, so you have to include it in the tvbuff,
and the dissector will put it into the protocol tree.
Also, make sure the top-level entry for the Frame Relay protocol
includes all the bytes preceding the payload, and none of the payload
bytes.
Export a routine to do Q.933-style dissection, and have the WCP
dissector call it, rather than duplicating that code in the WCP
dissector.
Don't register OSI network layer protocols with the "fr.ietf" dissector
table; it's now sufficient to register them with the "osinl" dissector
table, as the Frame Relay dissector now checks that.
Get rid of unnecessary checks for protocols being enabled (if the
dissector is always called through handles or dissector tables, the
common code for handles and dissector tables will do the checks for
you).
Get rid of some unnecessary #includes.
