/* A problem when trying to enforce airtime fairness is that we want to divide
* the airtime between the currently *active* stations. However, basing this on
* the instantaneous queue state of stations doesn't work, as queues tend to
* oscillate very quickly between empty and occupied, leading to the scheduler
* thinking only a single station is active when deciding whether to allow
* transmission (and thus not throttling correctly).
*
* To fix this we use a timer-based notion of activity: a station is considered
* active if it has been scheduled within the last 100 ms; we keep a separate
* list of all the stations considered active in this manner, and lazily update
* the total weight of active stations from this list (filtering the stations in
* the list by their 'last active' time).
*
* We add one additional safeguard to guard against stations that manage to get
* scheduled every 100 ms but don't transmit a lot of data, and thus don't use
* up any airtime. Such stations would be able to get priority for an extended
* period of time if they do start transmitting at full capacity again, and so
* we add an explicit maximum for how far behind a station is allowed to fall in
* the virtual airtime domain. This limit is set to a relatively high value of
* 20 ms because the main mechanism for catching up idle stations is the active
* state as described above; i.e., the hard limit should only be hit in
* pathological cases.
