Initial DEC 21143 support from Stephan Wilms <Stephan.Wilms@…>.
Comments follow:

This support is (for now) only available for the i386 target, because
that's the only testing platform I have. It should to my best knowledge
work in the same way for the "PPC" target, but someone should test
this first before it's put into the code. Thanks go to Andrew Klossner
who provided the vital information about the Intel 21143 chip.

(FWIW: my network card is a Kingston KNE100TX with 21143PD chip)
