[ECOS] Ethernet driver for MPC860

[Samuel Tardieu]

We've talked about this several times here, but unfortunately some
other work has distracted me and is likely to do so for a few more
weeks.

Here is the current state of our network.c, to be used with Tristan's
tcpip stack.

This file has been derived from RTEMS' network.c for PPC[1]. We will of
course appreciate bug fixes :)

Some things will have to be removed, for example calls to LCD display
(that were here for debugging), and some constants may need to be
renamed.

Good luck.
