Hi Lorenz Kolb, Thank you for answering.
It's interesting to see some info from your design files, PLB_TEMAC & HardTEMAC description from mhs, and kernel .config network section. The biggest problem that i actually do not understand what kind of problem is it, hardware or software or configuration.
