The OVN driver now makes uses of the "external" ports concept
that was introduced by Core OVN. For example, with this work a VM
with a SR-IOV port attached (VNIC type "direct" and no "switchdev"
capability) will now be translated into an "external" port which is
able reply to packets (e.g DHCP) from another host that were bypassed
in the hypervisor before. Note that, for this first interaction all
external ports will belong to the same HA group and will be scheduled
onto the same node.
