Corrupted packets from TCP socket with uClinux

I am connecting to the NIOS2 Cyclone III (3c120) development board and sending ethernet data into it using a TCP socket. Unless the data rate is kept very low (5 Mbps or less), I will get corrupted data on the NIOS board. I am using a build of uClinux. I have a C code patch installed to correct a known problem with checksumming.

Sending packets from the NIOS2 board is fine. It is only receiving packets that has this problem. The problem can be seen by riunning iperf and watching the lost packet error rate.

Is there another patch I need?

Thanks,
