One small thing, please put a version to your patches, so that people can refer easily to it. Since the patch version is dropped during merge, you don't need to worry about this one.

Although netdev does explicit locking, it is only valid from the ovs perspective, then only the ring ends used by ovs should be declared as single producer/consumer. The other ends that are used by the application should be declared as multiple producer/consumer that is the most general case.
