            Description

            It is expected that the firmware always accepts the generic request RCX_UNREGISTER_APP_REQ, independend from the sender of the request.

            Current firmware implementation only accepts this request if the sender is exactly the same. If the sender is different (which may happen using TCP Server by simply reconnecting the same application to firmware) the firmware rejects the request with error 0xC0000002.

            Same error would occur if application via DPM would change the value of field ulSrcID in request packet.
