My question is simple: I would like to use Simulink, just like Wireshark, to capture and display raw ethernet packets. I can not use TCP/IP or UDP. I only have remote device's MAC address(Ethernet II). With the current capability of Simulink Real Time Library or Instrument Control Toolbox, I was not able to do so. Do I need to do my own implementation of Ethernet interface in Simulink or do I need to take another approach?
