Seems like this topic ended here. So lets poke a little bit :)

There was just a patch (ok, lets call it workaround/hack) released by open-
mesh.com [1]. It is used in their setup to detect key cache problems and work 
around them.

Maybe this can also be relevant for this problem here. The patch was used with 
IBSS RSN but could also be helpful here.

The patch itself has (at least) one big problem. It is using some mac80211 
internals in ath_key_config_iter to make sure that the uploaded keys were 
actually programmed in the hardware. Without this check the keys could end up 
in the lower slots and thus break all connections.

So this patch could be a starting point for someone who wants to add a 
workaround which is acceptable by upstream.

Kind regards,
	Sven
