by the way, revolt, you said you did the checksum in hw, i asume this is a function normally done by the lwip? like crc?

The checksum calculation for the UDP packets is done by HW. Normally it is calculated by the lwip stack.

i see, i asume you do this with a custom instruction in the nios?, or did you put a discrete block of vhdl between the nios and mac/phy? and do you know if this can also be done with TCP packets? i asume so..
