It seems like these should be used from ieee80211.h, and/or added there
if they don't already exist?

you may leak key_info->key here?

That's a bit big to be forced inline, imho. if it's used only once the
compiler will inline it anyway.

but overall, why do you even need this? I don't think this is normally
handled in the driver, but wpa_s?
Anyway, I'm not convinced that we should really keep kicking this back
over minor issues like this ... better to merge it and fix later, imho.
