It really might be nice to take some of the ancient
hardware drivers in drivers/net and move them into
some separate subdirectory like:

	drivers/net/ancient
or
	drivers/net/antiques
or
	drivers/net/archaic
etc...

so there's some clear designation that these crufty
old drivers don't need to be touched anymore except
for maybe when kernel wide changes occur.
