When I create a virtio-user device with rte_hotplug it creates a kernel device (ie vtap0).
This is normal an the device has ifindex N.

But later when device is configured an started the original vtap0 device is deleted
and a new one is created (with ifindex N+1).  This seems like a bug, if nothing
else it unnecessary overhead and link flapping for routing daemons.

Noticed only while tracking down a bug where after vtap was created the
address was being set, but then disappearing.

Is this intentional? Is it documented?
