From 866a6a85d4680403a79b347b9e81a35d85f57471 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Wed, 12 Sep 2018 16:25:27 +0300 Subject: iwlwifi: mvm: rely on mac80211 to configure TWT support Mac80211 will check both the HE Capability IE and the Extended Capability IE, so set the TWT support bit when mac80211 tells us to.
