- * status, which drivers can ensure, see below.
- *

- * actually add STAs to the filter list, if this is done by the
- * driver in response to set_tim() (which will only reduce the race
- * this whole filtering tries to solve, not completely solve it)
- * this situation cannot happen.
- *
- * To completely solve this race drivers need to make sure that they
- * (a) don't mix the irq-safe/not irq-safe TX status/RX processing
- * functions and
- * (b) always process RX events before TX status events if ordering
- * can be unknown, for example with different interrupt status
