I've been investigating this problem a bit more and it seems that the symptom, at least, is that when we receive data with the more-data-buffered flag set, we immediately send a PS-poll which enables PS mode again. My guess is that it shouldn't send PS-poll but a null-frame with PS mode off. I still need to refresh my PSM knowledge a bit more before I can continue studying this. ;) -- Cheers, Luca. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
