Bluetooth: Add support setup stage internal notification event
Before the vendor specific setup stage is triggered call back into the core to trigger an internal notification event. That event is used to send an index update to the monitor interface. With that specific event it is possible to update userspace with manufacturer information before any HCI command has been executed. This is useful for early stage debugging of vendor specific initialization sequences. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
