From bb512ad0732232f1d2693bb68f31a76bed8f22ae Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 25 Aug 2014 12:08:09 +0200 Subject: [PATCH] Revert "mac80211: disable uAPSD if all ACs are under ACM" This reverts commit 24aa11ab8ae03292d38ec0dbd9bc2ac49fe8a6dd. That commit was wrong since it uses data that hasn't even been set up yet, but might be a hold-over from a previous connection. Additionally, it seems like a driver-specific workaround that shouldn't have been in mac80211 to start with.
