I'm not trying to force a driver to do anything, but I would definitely
like to suggest a driver give the management packets high priority,
and for drivers I can use and modify, I will try to make sure they work
properly.  Other driver writers can do as they wish.

If anyone can proclaim an API, then you can.  If you have another API in mind,
please detail it.  If no one cares, then I can just carry the hostap patch in
my own tree and move on to other things.
