Heh, a tiny bit, maybe? ;)

No, I don't think you are. For the airtime policy stuff in hostapd I use
queue length as a proxy for activity (any station which was backlogged
within the last N msecs is considered active). This is all tracked from
userspace through polling, though, so there's no counter for this in the
kernel. Should be possible to add it, though...
