ODL breaks ovs switch config on reconnect

Using Boron-SR2 artifact, OpenStack mitaka.
The networking setup is like this:

external-interface <> ext-linux-bridge <-A> br-floating(ovs bridge) <-> br-int

When ovs is restarted, port A ends up misconfigured.
I've collected the logs from such a restart (due to a segfault on the ovs side-working on that). The way this happens makes me think that netvirt pushes some configuration that it should.

To reproduce:

service openvswitch-switch restart
