This causes my older fxp's to loose the link:
fxp0: <Intel Pro 10/100B/100+ Ethernet> port 0xfcc0-0xfcff mem 0xfec00000-0xfecfffff,0xfedfd000-0xfedfdfff irq 15 at device 15.0 on pci0

Backing out this commit fixes the problem.
Note that I hardcode 'media 100baseTX mediaopt full-duplex '
in rc.conf for this interface, as its plugged into a really old switch
that doesn't do autoneg.
