            Description

            Sometimes it happens that the ulNumOfActiveSlaves field (located in  NETX_MASTER_STATUS) is not incremented although an IO connection to a target was successfully established and runs with no errors.

            This is due to a race condition related to the stack's internal packet communication.
            The issue shows up in case the target device sends its first IO frame very close (~ <0.1ms) to the ForwardOpen Response frame.
