[PATCH 3.14 40/83] iwlwifi: mvm: disable uAPSD due to bugs in the firmware

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

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

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.
