>Show me the output of "sysctl dev.vr.0.stats=1" and "netstat -ndI vr0".

soekris1# sysctl dev.vr.0.stats=1
dev.vr.0.stats: -1 -> -1


Please check the output of console. It would have printed some MAC
counters maintained in driver.

soekris1# netstat -ndI vr0

No Ierrs, so MAC counters would be more helpful here.
