[PATCH] net/sk98lin: correct buggy VPD in ASUS MB

From: Jeff Lightfoot <jeffml@pobox.com>

The following patch to net/sk98lin/skvpd.c was put together by Marc Bouget,
mbouget at club-internet.fr.

This patch works around a corrupt EEPROM (VPD?) in the ASUS K8V Deluxe SE
motherboard ethernet chipset and allows the network driver to work
correctly.  We have written to ASUS and the sk98lin maintainers but have
not heard anything back.
