If anyone has any objections, please let me know. ------------------ From: Emmanuel Grumbach 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.
