description:
Add driver for SKNET Personal and MC+ - AMD Lance 7990 based ethernet cards.
Both models tested and seem to be quite stable and fast.
Thanks to:
- Hans Hubner <hans%Huebner.org@localhost> for giving me the cards for testing
- Georg Klug of Syskonnect, who provided me with hw docs for these cards,
very promptly and willingly - I wish all vendors would be like this
- Alfred Arnold, Linux SKNET driver author, for giving me valuable Syskonnect
contact :)
