The creation of a tunnel vport (geneve, gre, vxlan) brings up a corresponding netdev, a multi-step operation which can fail. For example, changing a vxlan vport's netdev state to 'up' binds the vport's socket to a UDP port - if the binding fails (e.g. due to the port being in use), the error is currently ignored giving the appearance that the tunnel vport creation completed successfully.
