Comment 1 for bug 1914231

By the gaps list (https://docs.openstack.org/neutron/latest/ovn/gaps.html) routed provider nets not supported/working with OVN now, there's an RFE for it:
https://bugs.launchpad.net/neutron/+bug/1865889

Not sure which part should be expected to work, perhaps a clean rejection would be better till the RFE finished.
