From 143b0b2ae8c1f0c0e036ec859d0a49482892234b Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Wed, 26 Oct 2016 14:21:27 +0300 Subject: [PATCH] iwlwifi: mvm: fix PS-Poll enablement We added the uAPSD enabled ACs and that made the firmware choose to pull frames with uAPSD trigger frames instead of PS-Poll. Fix that.
