Network peer detection broken for single port configuration

When the protocol stack is used with the profinet switch and is configured for single port operation by setting startup parameters ulActiveLLDPPorts and ulActiveProfinetPorts to 1 the network peer detection will show unexpected behavior. Depending on the MRP PDEV parameter values passed during connection establishment, the device might stop or start reception and transmission of LLDP peer detection frames.

IT is expected that LLDP continues operation as required by the specification.
