Comment 4 for bug 1618433

in neutron-openvswitch-agent.py I found this code:

        if not self.l2_pop:
            self._setup_tunnel_port(self.tun_br, tun_name, tunnel_ip,
                                    tunnel_type)

It seems the tunnel interface gets created only when L2 population is not configured. I was under impression that l2_population is required for tunnel type vxlan.
