Sorry, this patch doesn't work at all especially when IPV6=m and TIPC=y. For
example, when we use the combination of the kernel config options, error appears
like:

net/built-in.o: In function `tipc_udp_send_msg':
/home/ying/work/tipc/tipc2.0/net-next-2.6-debug/net/tipc/udp_media.c:196:
undefined reference to `ip6_dst_lookup'
make: *** [vmlinux] Error 1

Instead, I ever tried to fix the issue several days ago. Please refer to the thread:

https://patchwork.ozlabs.org/patch/448836/

According to the suggestion David gave lastly, we should separate the UDP media
as an independent module, make TIPC_MEDIA_UDP depend on (IPV6 || IPV6=n), and
mark TIPC_MEDIA_UDP tristate. Now I am busy doing this following the proposal.

Regards,
Ying
