BMAC Ethernet Driver

[Nathan Whitehorn]

Here is a first draft of a driver for the BMAC(+) built-in ethernet 
found at least on G3 macs. It is based on some earlier work by Peter 
Grehan, and some parts of it have been lifted from the FreeBSD gem driver.

It works well on my 400 MHz blue & white G3, which has a BMAC+ 
controller. I'd appreciate testing on earlier machines, which have 
buggier controllers (early G3 iMacs especially).

The source is set up to build a kernel module. I haven't tried any 
integration with the build system yet.
