    BLE_ACL_BUF_SIZE:
        description: >
            This is the maximum size of the data portion of HCI ACL data
            packets. It does not include the HCI data header (of 4 bytes).
        value: 255

    BLE_HCI_ACL_OUT_COUNT:
        description: >
            This count is used in creating a pool of elements used by the
            code to enqueue various elements. In the case of the controller
            only HCI, this number should be equal to the number of mbufs in
            the msys pool. For host only, it is really dependent on the
            number of ACL buffers that the controller tells the host it
            has.
