Hi Jouni,

Indeed, no upstream driver is currently using it, but we plan to commit 
our new driver (that uses it) to the upstream linux kernel and anyway it 
seems like it can be useful to others.

Should I ping the fixed patch again once we upstream or can you already 
accept it now ?

If the latter, I will publish a fixed patch (with the whitespace damage 
fix and proper nl80211.h documentation)

Thanks,

Shay
