I don't think so. It's not that this is an actual queue anyway. It just acts as a buffer to queue up one or two packets in the small race window of actually filling up the DMA rings and stopping the mac80211 queue. (It also acts as a context dispatcher in the first place, though). So the "looping through the queue" just means checking if one or two packets can be transmitted now. _______________________________________________ b43-dev mailing list [email protected] http://lists.infradead.org/mailman/listinfo/b43-dev
