+ * thinking only a single station is active when deciding whether to allow

+ * To fix this we use a timer-based notion of activity: a station is considered

+ *
+ * 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
