Jonathan,
can you please be more specific on your test setup? Are you running this with the Profinet stack from Molex? Or are you trying Profinet firmware standalone? How do detect packets send to the host? What packet types are you uisng for test?
For sure the Profinet example should receive TCP/IP packets using the Profinet device MACs (there are 3! - one per port and a device MAC). Otherwise Profinet would not work as it requires standard TCP/IP and the NDK to process e.g. DCP and LLDP.
Regards,
