Use sk_mark for IPv6 routing lookups

Ok, I'll just drop that part, I'm not sure what should be done in this case. > Also, in this patch you are doing that for SIT (v6-in-v4) tunnels only, and not doing it for v4-in-v6 or v6-in-v6 tunnels. Any reason for that? I just sent that patch out too quickly, here's a better one with the updates. Add support for IPv6 route lookups using sk_mark.
