From ceaad3c435964f601602531d0f6f7deaff329e21 Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Wed, 12 Feb 2025 08:22:58 +0200 Subject: wifi: cfg80211: expose update timestamp to drivers This information is exposed to userspace but not drivers. Make this field public so that drivers are also able to access it. The information is for example useful for link selection to determine whether the BSS corresponding to an MLO link has been seen in a recent scan.
