Seems OK from a userspace point of view. I am a little concerned that
downgrading userspace without deleting and re-creating the datapath
(e.g. via "force-reload-kmod") will result in a totally broken setup
since userspace will then drop every packet from the kernel.
Is that something that occurs occasionally in installations? Utilizing
the version field in the genl header could be used to track this and
clear user_features.
