PATCH 1/1 IPv6: Fix 6RD build error

Fix build error introduced in commit fa857afcf - ipv6 sit: 6rd (IPv6 Rapid Deployment) Support. Struct in6_addr is the issue. I'm only seeing this on x86_64 systems, not on 32-bit with same IPv6 config options, so it could be there's a missing forward declaration somewhere, but including the correct header file fixes the problem too.

In file included from net/ipv6/ip6_tunnel.c:31:
include/linux/if_tunnel.h:59: error: field ‘prefix’ has incomplete type make[2]: *** [net/ipv6/ip6_tunnel.o] Error 1
make[1]: *** [net/ipv6] Error 2

Funny, I didn't see this on sparc64.

Applied, thanks Brian!
