>Description:
vr driver claims "vr0: MII without any phy!" when coming back from Windows.
# pciconf -l | grep vr
vr0@pci0:11:0: class=0x020000 card=0xa1111259 chip=0x30651106 rev=0x42 hdr=0x00
% grep '$FreeBSD' /usr/src/sys/pci/{if_vrreg.h,if_vr.c}
/usr/src/sys/pci/if_vrreg.h: * $FreeBSD: src/sys/pci/if_vrreg.h,v 1.7.2.1 2000/07/05 21:43:59 wpaul Exp $
/usr/src/sys/pci/if_vr.c: * $FreeBSD: src/sys/pci/if_vr.c,v 1.26.2.4 2000/08/04 23:45:28 peter Exp $

>How-To-Repeat:
1. Boot Windows9x which has VIA Rhine network driver.
2. Select reboot from Windows startup menu and boot FreeBSD with GENERIC kernel.
>Fix:
a. Power off after using Windows.
b. Apply next patch to if_vr.c. But I don't know why it works.
