Subject: [PATCH] wcn36xx: Fix missing frame timestamp for beacon/probe-resp
Git-commit: 8678fd31f2d3eb14f2b8b39c9bc266f16fa24b22
Patch-mainline: v5.15-rc1
References: git-fixes
When receiving a beacon or probe response, we should update the
boottime_ns field which is the timestamp the frame was received at.
(cf mac80211.h)
This fixes a scanning issue with Android since it relies on this
timestamp to determine when the AP has been seen for the last time
(via the nl80211 BSS_LAST_SEEN_BOOTTIME parameter).
