Hi Johannes,
Below is a warning I get with your latest QOS patch series,
rt61pci registers 4 queues, but apparently the WARN_ON()
in ieee80211_wake_queue is being triggered.
void ieee80211_wake_queue(struct ieee80211_hw *hw, int queue)
{
struct ieee80211_local *local = hw_to_local(hw);
if (netif_is_multiqueue(local->mdev)) {
netif_wake_subqueue(local->mdev, queue);
} else {
WARN_ON(queue != 0);
netif_wake_queue(local->mdev);
}
}
CONFIG_MAC80211_QOS is enabled in the kernel configuration,
and debugfs shows that rt2x00 is serving frames over multiple
TX queues, so the multiqueue is working...
Ivo
