From 46f208b9e7deda8be6eb915e0d1c65fbf3ae8c70 Mon Sep 17 00:00:00 2001 From: Ayala Beker Date: Wed, 20 Mar 2024 09:14:02 +0200 Subject: [PATCH] wifi: mac80211: don't select link ID if not provided in scan request [ Upstream commit 80b0aacd1ad046b46d471cf8ed6203bbd777f988 ] If scan request doesn't include a link ID to be used for TSF reporting, don't select it as it might become inactive before scan is actually started by the driver. Instead, let the driver select one of the active links.
