I think no one is arguing that we don't eventually need some better
abstraction.  But as long as it is one-bridge and one-user, if the
patches otherwise have merit, add functionality that was missing
before and don't regress, then lack of infrastructure to match up
bridge and driver isn't something I will care about too much yet.
Things are allowed to be in-progress.  A missing abstraction for a 1:1
relationship is fine.

Now as we start getting a few more bridge devices and users, then I'll
start blocking patches until some sort of generic bridge loader is
sorted out.
