This patch-set mainly does four things: 1. Add handler to send WMI_SET_CURRENT_COUNTRY_CMDID to firmware. 2. Use WMI_SET_CURRENT_COUNTRY_CMDID to set country code for WCN7850. 3. Implement 11d scan offload, and update new channel list to firmware when 11d scan finished. 4. Store country code, and update it to firmware after device recovery. With this patch-set, WCN7850 can do 11d offload scan and update country code to firmware successfully. Note: This patch-set is an old patch-set in public review written by Wen Gong. Just resend it for him.
