I couldn't find in in mac80211, but a few (but not all) of the fullmac
drivers seem to do it.

Andrey: the attached patch may help, but given what you've written in
your other email (which I'll respond to separately), I don't think it
will fix things. Note that it's against wireless testing (+ private
changes). Should apply cleanly to an older tree after you account for
the file move.
