While the reverse order may work, it's considered invalid by OVN and not
guaranteed to work properly since OVN may not necessarily know which of
two ports is the one to configure.
This configuration also triggered a bug in OVN where tearing down a port
after deploying a new one resulted in removing flows that serve the
port.
There is a patch up for review for OVN [1] to better handle multiple
assignment of the same port, but it doesn't make the setup any more
valid.
