This was going towards executing actions in user-space if the in_port is
not present in the datapath and a recirculation action is added.  That
discussion has moved on a bit and it now seems that the approach I took is
not the favoured one.

I'll remove the patches in this patchset that implement that approach,
rebase the remaining patches and repost.
