Subject: [PATCH] Revert "ath10k: drop beacon and probe response which leak from other channel"
Git-commit: 45b4eb7ee6aa1a55a50831b328aa5f46ac3a7187
Patch-mainline: v5.17
References: bsc#1206451
This reverts commit 3bf2537ec2e33310b431b53fd84be8833736c256.
I was reported privately that this commit breaks AP and mesh mode on QCA9984
(firmware 10.4-3.9.0.2-00156). So revert the commit to fix the regression.
There was a conflict due to cfg80211 API changes but that was easy to fix.
