Locally bound packets are in fact the one case we do not
want source address validation to occur for performance
reasons, it's the whole reason this is coded the way that
it is.

Turn on rpfilter if you have a machine directly exposed
to the internet with no ingress firewalls/routers there
to validate the source address.

I am not applying this patch.
