        When adv report flow control is enabled, The ADV lost event will be generated when the number
        of ADV packets lost in the controller reaches this threshold. It is better to set a larger value.
        If you set `BT_CTRL_BLE_ADV_REPORT_DISCARD_THRSHOLD` to a small value or printf every adv lost event, it
        may cause adv packets lost more.

        data and device address filtering. All different adv packets with the same address are allowed to be

        filtering. All same advertising data only allow to be reported once even though they are from

    help
        If the period value is non-zero, the controller will periodically clear the device information
        stored in the scan duuplicate filter. If it is 0, the scan duuplicate filter will not be cleared
        until the scanning is disabled. Duplicate advertisements for this period should not be sent to the
        Host in advertising report events.
        There are two scenarios where the ADV packet will be repeatedly reported:
        1. The duplicate scan cache is full, the controller will delete the oldest device information and
        add new device information.
        2. When the refresh period is up, the controller will clear all device information and start filtering
        again.
