I do not like the need for a flag when the VRF is created. If something
changes with the firewall rules, it means a user has to delete and
re-create the VRF which is really expensive.

It would be better to detect this on the fly - similar to how it detects
the default qdisc and avoids the recirculation on Tx when the qdisc is
the default.
