All functions starting with 'ethernetif_' (not 'ethernet_') are part of the
netif driver that interfaces lwIP to your ethernet interface (or MAC). Since
the downloadable lwIP code is not a ready-to-use program but only a TCP/IP
library targeted on portability, there is no driver included. A driver is
normally written when porting lwIP to some hardware. Since you are using NIOS,
chances are high that a driver for your MAC already exists.
