By the way, the FreeBSD and the NetBSD if_vr.c driver are derived from the same original source, but have evolved since then.

 >> Fix:
 
 Hello,
 
 Now that is interesting, I happen to have the exact same ethernet card
 onboard of my motherboard:
 
 redqueen# cat /var/run/dmesg.boot | grep vr
 vr0: <VIA VT6102 Rhine II 10/100BaseTX> port 0x7400-0x74ff mem 
 0xf0000000-0xf00000ff at device 18.0 on pci0
 miibus0: <MII bus> on vr0
 vr0: Ethernet address: 00:0c:6e:8d:88:ad
 
 I am using this for like two years now without a problem. Can you tell
 me whether you see traffic passing over the vr0 card at all? (tcpdump
 -n -i vr0 would give information about that), do you see arp adresses
 being exchanged? What happends when you try to setup traffic towards
 another host?
 
 What do you have installed on your system? (anything of these might
 prevent your data other then ping, being blocked)...
 
 Hope to see your answers soon!
 
 Cheers,
 Remko
