There&#39;s some registers in the LAN91C111 that you&#39;ll have to set. Go to SMSC&#39;s site and download the datasheet for the chip. The driver that ship with the Nios dev kit sets it to auto-negotiate the speed, so just search for where it does that and change it to use whatever speed you want.
