GNU Mach network driver update.

[Alfred M. Szmidt]

Hey,

as I promised, here is a driver update for some NIC's in GNU Mach.  I
haven't made a detailed list of what NIC's have been touched.  But
here is a list of what chipsets have been mucked around with: 3c59x,
eepro100, epic100, ne2k-pci, rtl8139, tulip, via-rhine, yellowfin.

The following _new_ drivers have been added: sundance, winbond-840,
hamachi, myson803, natsemi, ns820.  To enable these new drivers just
do --enable-DRIVER.

For drivers that have been disabled for various reasons, see
[gnumach]/i386/linux/Drivers.in.

Have fun, and please beat the crap out of all the drivers you can.
Specially ones that are common.

Since the patch is huge (~1Mb), I'm not sending it to the mailing
list, instead you can snatch it from:

Happy hacking!
