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...
