This sound fine.

However, it'd be good to mention that you're also adding it to
mac80211, or preferably even split the patch into two, one to add the
feature and one to make use of it in mac80211.

Once you do that, you'll quite likely also notice that with just the
first of the patches, the thing is broken and always reports a 0 AID.

That's because you need to make this conditional on the right filled
flag.
