Triggering 11d algorithm on the scan results of a normal scan helps in completely avoiding a separate 11d scan for determining regdomain. This indirectly helps in speeding up connections on station interfaces on the chipsets supporting 11D scan. To enable this feature, send WMI_11D_SCAN_START_CMDID just before sending WMI_START_SCAN_CMDID if the firmware advertises WMI_TLV_SERVICE_SUPPORT_11D_FOR_HOST_SCAN service flag. WCN6750 & WCN6855 supports this feature.
