Hi,

There's an awful lot of bookkeeping required to establish and keep an Ethernet link going. You're looking for performance, so what I would suggest is use the NIOS for basic link establishment and management but use DMA to transfer the payload into your own logic and back again. Have a look at:

Otherwise you're looking at implementing the whole protocol stack in logic rather than software.

Mark.
