I have a machine (x86-32, 2.6.20.3) with two ethernet interfaces: a 100M Tulip and a 1G VIA Velocity. Both are connected to a common VLAN-capable switch. The eventually desired configuration is VLAN support on the Gbit interface.
If I set the Tulip's switch port to tagged, and configure a VLAN on the Tulip interface appropriately, packets flow as expected. But if I try the same configuration on the Velocity interface, things don't work. I can see tagged ICMP pings go out, but no responses come back. I can see ARP requests and responses on the target machine. If I manually configure the ARP caches, I can see the pings and responses on the target machine. If I kludge the target's ARP cache to point back to the source's Tulip interface, I can see the ping responses on the Tulip interface. But I don't see the ping responses on the Velocity interface. The vlan interface name and address is the same, so it can't be firewall rules distinguishing. I have tried various ping sizes from 0 to 1472. Is this likely to be a problem with the via-velocity driver? Is anyone working on it? Or should I just get a different gigabit card?
