This patch-set mainly does four things: 1. Add handler to send WMI_SET_CURRENT_COUNTRY_CMDID to firmware. 2. Implement 11d scan offload, and report country code to firmware by WMI command WMI_SET_CURRENT_COUNTRY_CMDID. 3. Use WMI_SET_CURRENT_COUNTRY_CMDID to set country code for WCN7850. 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.
