            Description

            If no host application has registered (at GenAp) and the EtherNet/IP stack tries to send an object change indication to the application, the firmware will crash.

            This happens only in case the indiaction packets are triggered internally and not by a set attribute request coming from the network.

            Affected situations:

            1. Attribute 5 (Interface configuration) of TCP/IP Interface object is set when obtaining the IP address configuation from a DHCP/BOOTP server.
            2. Attribute 11 (Last Conflict detected) of TCP/IP Interface object is set in case an address conflict has been detected.
