Sure.

well, i'll prefer it to call with my name: lazy man's hack ;)

I think there is more things to do in ath9k. Create the list and we can 
talk about it. For example one of it: I needed some time to understand 
how some parts of code relate to the hardware. Especially Rx and Tx 
descriptors. Some comments in header will help... I can add some of them 
(may be it will help other beginners), but i afraid that i spend time 
but my patches wont be included.
