From 8cd5c0847160aa9482d7f93ed63c4d72bad70cdf Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Mon, 11 Oct 2021 18:18:00 +0300 Subject: [PATCH] ath11k: 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.
