Hello, I've brought this up already on the ath11k/ath12k list: https://lore.kernel.org/ath12k/CZA2NS7J83D4.18SU6W9R96KPY@gmail.com/ To my knowlege, nothing upstream has been posted so far by QCA. In non mainline sources there is a patch to support ath12k: https://git.codelinaro.org/clo/qsdk/oss/system/feeds/wlan-open/-/blob/win.w= lan_host_opensource.3.0/patches/ath12k/897-wifi-ath12k-Add-support-for-STA-= mode-to-trigger.patch My guess is that ath11k works the same way. It would be great if QCA people could mainline this, it seems like a small enough and isolated feature that could be pushed without side effects.=20 > > > Best regards > Alexander Wilhelm
