Arrgh! Well, you can tell that I don't really know what I am doing with
socket code!
Your original code inserted into dhcp6.c was the right thing to do. I
just changed IPPROTO_IPV6 to SOL_SOCKET and it looks like it works (I
have two of them running anyway). At this point I do now know if you
need the V6ONLY or not.
Now to do some real testing!
