I've hooked up soreceive_dgram() only for UDPv4, but Paul Saab has volunteered 
to do UDPv6 testing.  Asuming that goes well, I'll hook up UDPv6 sometime soon 
also.  As far as I know, no code is missing -- in principle, soreceive_dgram() 
could also be used for IP raw sockets, Appletalk, IPX, etc, as well.
