I backported there changes from OpenBSD nfe driver.
(https://github.com/openbsd/src/commits/master/sys/dev/pci/if_nfe.c)

Tested changes in 12.0-RELEASE on Apple MacBook "Core 2 Duo" 2.4 13" (Mid-2010) with nForce MCP89 chipset:

pciconf -lv | grep MCP

Actually, just needed to add define for device id.
