stable inclusion from stable-5.10.67 commit be457b27dd0a0428bcf9dd10156049c20031fb34 bugzilla: 182619 https://gitee.com/openeuler/kernel/issues/I4EWO7
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 8678fd31f2d3eb14f2b8b39c9bc266f16fa24b22 ]
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).
