When using the MC9S12NE64 as a ethernet device we are experiensing problems with some network switches. The network traffic sent by the NC64 isn't getting thru through the switch.

We are running the device in 10MBit mode(full duplex) and with auto negotiation turned off. We have auto neg turned of since the errata on the NE64 states that the auto-negotaition feature might not be reliable with some network hardware.

We've built the design of the ethernet interface from the AN2759 article, and we are running the MCU at 25Mhz. Does anyone know what might be causing this?
