While looking for a place to add a new bitfield in ipv6_pinfo, I've found a 32 bit hole (in 64 bit mode) at the beginning of the struct. Since dst_cookie is used in the output fastpath, I've moved this field to fill the hole. The original place of dst_cookie is now empty, but can become a place to add further fields to the struct.
