What I mean is that it returns an ordinary dst, as if that souce
address _hadn't_ been removed from the interface, even though I just
removed it. Is this buggy behavior? If so, let me know and I'll try to
track it down. The expected behavior, as far as I can see, would be
the same that ip_route_output_flow has -- returning -EINVAL when the
saddr isn't valid. At the moment, when the saddr is invalid,
ipv6_stub->ipv6_dst_lookup returns 0 and &dst contains a real entry.

Regards,
Jason
