While for the customer, if they are upgrading their ovs to a new version, will they have to reconfigure the interface? If this is the case, personally I do not think this is a friendly way to them.</div>

When I replace the openvswitch.ko with a new modified one, the configuration on the bridge such as br0 is lost.<span>

<div>I think you can use network scripts and restart your network to configure back the br0's ip address whenever you reload openvswitch.ko</div>
