It turned out that upon a power save mode change the firmware will set a special flag onto the last outgoing frame tx status (which in this case is almost always the designated PSM nullfunc frame). This flag confused the driver; It erroneously reported transmission failures to the stack, which then generated the next nullfunc. and so on...
