[PATCH 3.13 063/151] iwlwifi: mvm: disable uAPSD due to bugs in the firmware

[Kamal Mostafa]

3.13.11.1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Emmanuel Grumbach <emmanuel.grumbach at intel.com>

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.
