I did only a 30 sec review (right now no time for proper review because
I have quite a lot of catching up after vacation) but based on what I
saw the driver looks promising. So I agree with Marcel, you should try
to submit this via linux-wireless first and only use staging as the last
resort.

I recommend to post the patch to linux-wireless now and see what
comments you get. Then I can also when a proper review and have better
guidance.
