Comment 3 for bug 1865889

The RFE was discussed in the drivers meeting: http://eavesdrop.openstack.org/meetings/neutron_drivers/2020/neutron_drivers.2020-03-13-14.00.log.html#l-16
We decided to accept it. The OVN subteam can choose solution (1 or 2) which is easier/better to go with.
The main downside of approach 2, which is limit for one segment per host isn't really issue for Neutron currently as we have such limitation in case of other in-tree drivers too.
