From 4c26033d75e414cf0c500055ec58511f93684d87 Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Thu, 16 Mar 2023 12:11:44 +0800 Subject: [PATCH] wifi: ath12k: Identify DFS channel when sending scan channel list command WMI_CHAN_INFO_DFS flag should be set when configuring a DFS channel included in scan channel list. Without it, firmware will not send a probe request frame which is needed in connection to an AP configured with hidden SSID/network_id. So fix this to allow probe request frames to be sent in cases where a beacon frame has been seen on the channel first.
