Running the test added with a recent fix on a driver with persistent NAPI config leads to a deadlock. The deadlock is fixed by patch 3, patch 2 is I think a more fundamental problem with the way we implemented the config.
I hope the fix makes sense, my own thinking is definitely colored by my preference (IOW how the per-queue config RFC was implemented).
