Hello Maintainers, We have discovered that when userspace registers a broadcast (non-connectable) advertisement with scan response data, it exposes a limitation in the new extended MGMT APIs. At the time that the parameters are registered with the controller, kernel does not yet have the advertising data and scan response (coming in a separate MGMT call), and will default to a non-scannable PDU. When the MGMT call for data/scan response is received, the controller will either fail when we request to set the scan response, or return success and not use it. This series along with another in kernel will allow userspace to pass a flag with the params request indicating if the advertisement contains a scan response. This allows kernel to register the parameters correctly with the controller. The patch is tested with a scannable broadcast advertisement on Hatch and Kukui chromebooks (ext and non-ext capabilities) and ensuring a peripheral device can detect the scan response.
