I remembered that there was an onboard NIC (msk0), so I enabled it and
moved one IP address to the msk0. Then, the problem was disappeared
for that IP address.

So, I believe that vge driver of 8.0R is somewhat broken.

Is there anyone who can fix the problem? I'm willing to test patches
on my PC if available.

Anyway I'm considering to purchase two more NIC cards, because I need
a quick fix...
