Hi,

Cool stuff. Minor (really) comments below.

Can both really happen at the same time? Or why are they flags rather
than just an action code?
 
> + * @ampdu_action: Ask low-level driver to perform a certain A-MPDU action

I think we usually just say "Perform a certain A-MPDU action" because
these comments are more for driver writers than mac80211 people and they
like to be told what to do ;)

small typo: "performed"

small typo: "Starting"

@ssn will highlight the variable name afaik. I need to get my docbook
stuff up to be mergeable.

I personally prefer indentation to right after the opening parenthesis
and that's the style over the whole struct.
