	Doing things in the driver is going in the opposite direction
Jouni has been going with HostAP. You want as much as possible to do
things in user space (i.e. as a daemon).
	If you can't do what you are trying to do from user space,
then I would consider that a bug.

	If you do it in user space, it becomes totally trivial.
	Note that in the latest driver release, Jouni has added more
user APIs to join the AP of your choice.
