There might be people who would want to > test experimental v6 paths as well if possible... 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.
