Summary: 


   Here is the answer to your question about raw IP. I suppose several people
have answered as it is quite simple. All you have to do is add an entry to the
protocol switch table in the file /sys/netinet/in_proto.c; this should be an
exact duplicate (and can directly follow) the entry for normal raw IP, but the
value IPPROTO_RAW should be changed to your own value IPPROTO_XNET (= 15).
To be tidy, define this latter thing in /sys/netinet/in.h by the way.
   If you are serious about wanting to remove the IP headers completely, then
your task is much harder (I know 'cos I've done it...). Good hacking!
