+Subject: [PATCH] mac80211: remove iwlwifi specific workaround that broke sta
+ NDP tx
+
+Sending nulldata packets is important for sw AP link probing and detecting
+4-address mode links. The checks that dropped these packets were apparently
+added to work around an iwlwifi firmware bug with multi-TID aggregation.
