Aha, now i understand where both you and Patrick are coming from. So
you literally have to hit the main(or default) table in the reverse
source validation. How does the workaround (that you suggested) work
then? i.e you are going to fail the RTN_UNICAST test no matter what.

Dave, give me some short time to mull this over. I am not sure i like
the sysctl approach - we may have to just revert the whole thing
instead.
