    BLE_LL_ISO_HCI_FEEDBACK_INTERVAL_MS:
        description: >
            Enables ISO synchronization feedback using vendor-specific HCI event.
            The event is sent at configured interval after completed ISO event
            and contains BIG handle, number of expected SDUs per ISO interval
            and difference between expected vs actual number of SDUs queued in
            controller.
            The expected number of SDUs queued after each event is number of
            SDUs required for each ISO event (i.e. including pre-transmissions)
            minus number of SDUs expected per each ISO interval.
            The host can use feedback to e.g. adjust for jitter between audio
            clock and LL clock.

            Threshold is defined as number of ISO events. If number of queued
            SDUs exceeds number of SDUs required for single event (i.e. including
            pre-transmissions) and number of subsequent ISO events defined by
            threshold value, the controller will drop any excessive SDUs and
