The old ZD1211 chip doesn't support queuing and the new ZD1211B chip has support, but it is unclear how to put packets in the different queues. However the error condition here is, that packets can't be transmitted over the USB, which will affect all queues. Sure one could manage different high level marks for the different queues, but this is all theoretical currently. I could have coded with the explicit knowledge that we support only one queue, but it is really work the hassle. > > +/** > > + * wake_queues - wakes all queues > > + * @hw: a &struct ieee80211_hw pointer > > + * > > + * Such a function is not provided by mac80211, so we have to provide them on > > + * our own. > > + */ > > +static void wake_queues(struct ieee80211_hw *hw) > > It is :-) Look for ieee80211_wake_queues. But as I said, you shouldn't need > that. I provided the patch to add ieee80211_wake_queues(). Sorry for missing the moment, when it has been integrated. I will update the patch. -- Uli Kunitz - 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
