Subject: iwlwifi: mvm: disable uAPSD due to bugs in the firmware
From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
commit a82dda6cd492b8c88952be6f6527f3656f7ac585 upstream.
The current firmware advertises support for uAPSD, but
critical bugs force us to disable the feature.
When a fixed firmware will be available, we will be able to
re-enable uAPSD.
