>Description:
After an hour or so of traffic on my nic the kernel reports
rx error: unknown rx error.

after that the stack is broken and the machine must be rebooted before
any traffic can leave the machine.

The machine is a PC with a celeron, a DFI M/B with an intel chipset,
the nic is a miibus/rhine compatible DLINK 530TX.  My network is just 2
back to back fbsd boxes. They both have the same DLINK in them but my
second machine is running fbsd 3.4R.  The 3.4 machine has never had 
any problems.


>How-To-Repeat:
~60 minutes of semi-constant NFS(udp), web and other 
misc traffic across VR0
>Fix:
not known.
