Of course this depends a lot on the device - ethernet on a  SCC  port
on  a MPC8xx is different from ethernet on a FEC on a MPC860-T or -P,
which in trun is different from ethernet on a FCC on a 8260. Add  the
different  speed  of  the  CPU's, differend speed of their bus inter-
faces, etc.

It makes a LOT of difference. But then, there is also a price

If programming was easy, they wouldn't need something as  complicated
as a human being to do it, now would they?
