+
+Michael reported that p54* never really entered power
+save mode, even tough it was enabled.
+
+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...
