From 6c7c30adf79eff6141e43434314a03fd9de0dc1c Mon Sep 17 00:00:00 2001 From: Kang Yang Date: Wed, 28 Feb 2024 17:35:36 +0800 Subject: [PATCH] wifi: ath11k: change scan flag scan_f_filter_prb_req for QCA6390/WCN6855/QCA2066 Current ROC scan will filter probe request. So P2P device cannot receive probe request. But it is necessary for P2P mode. A P2P device cannot be discovered if it doesn't respond to others' probe request. In addition, station won't filter probe request with common scan. But for station, there is no needed to receive probe request. Based on the above two points, change scan flag scan_f_filter_prb_req for QCA6390/WCN6855/QCA2066.
