Because of the stupid current behaviour of the ipx code. It tries to
use the same host-part of the ipx address on all the interfaces. For
that it use the MAC address of the first interface that is ifconfig'ed
with an ipx address. But for ipx to work on ethernet, the mac address
of the interface must be the same as the host part of the ipx address,
so the mac address of the 2nd and 3d interface must be changed. This
works correctly on the edX devices, but not on the deX devices.

I have this fixed here (so that each interface keeps its own mac address
and ipx use that), but I want to fix a few more things before I commit it.
