Subject: iwlwifi: mvm: fix PS-Poll enablement
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=143b0b2ae8c1f0c0e036ec859d0a49482892234b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
