It's just, you know, new to open source. :-) In my opinion this doesn't really belong into a rate control module. There should be a tx scheduling API to take care of this. Before I implement something like this, I plan on exposing all per-station driver queues to mac80211. This is necessary for a few other things anyway, e.g. unifying software aggregation logic and fixing its buffer management. - Felix -- 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
