Subject: mac80211: simplify wmm check during association
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=76f0303d61b3c7f1918ab63a64e77450a4418a60;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mac80211: simplify wmm check during association

Instead of setting assoc_data->wmm_used solely
based on the BSS also take into account our own
capabilities and later check those.

Also rename "wmm_used" and "uapsd_used" to just
"wmm" and "uapsd".
