Guido van Rooij b3ac88f13f New vx driver for:
3COM 3C590 Etherlink III PCI,
        3COM 3C595 Fast Etherlink PCI,
        3COM 3C592 Etherlink III EISA,
        3COM 3C590 Fast Etherlink EISA,
        3COM 3C900 Etherlink XL PCI and
        3COM 3C905 Fast Etherlink XL PCI.

This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.

Especially the 3c59X support should be pretty stable now.
