-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.
