3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Emmanuel Grumbach <emmanuel.grumbach@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.
