tcpdump/sctpConstants.h
guy c4aa80257a The SCTP dissector is only called for SCTP packets, so there's no reason 
for it to check the protocol number in the IP header.

Have the IPv6 dissector call the SCTP dissector for SCTP packets.

Get rid of the definition of IPPROTO_SCTP in sctpConstants.h, so we
don't have problems if <netinet/in.h> also defines it.
