From cf0425eead75687078369e48691b8a5f624885cd Mon Sep 17 00:00:00 2001 From: Kang Yang Date: Mon, 5 Feb 2024 19:03:30 +0200 Subject: [PATCH] wifi: ath12k: designating channel frequency for ROC scan For P2P mode, the WLAN interface may be requested to remain on a specific channel and then to send some management frames on that channel. Now chananel frequency of wmi_mgmt_send_cmd is set as 0. As a result, firmware may choose a default but wrong channel. Fix it by assigning chanfreq field with the ROC channel frequency. This change only applies to WCN7850, other chips are not affected.
