BUG: iwlwifi (dvm) queue mapping inconsistent with nl80211 tx_control_port

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I currently run a wpa_supplicant version which uses nl80211 control port
tx. The following warning in the iwlwifi driver was triggered:

WARN_ON_ONCE(is_agg &&
             priv->queue_to_mac80211[txq_id] != info->hw_queue);

Kind regards,
Markus
