Any ideas how I might troubleshoot why packets that come
into lan1.1 (port 0) aren't being pushed to the CPU port?

The switch supports port monitoring, with seperate ingress and egress
mapping, thus you could place another PC on another port and direct
traffic towards that, and by tcpdump inspecting ingress and egress on
the different physical ports... Thats how I debugged it once...

I also used/implemented the VLAN violation interrupt, while I debugged
the VLAN setup.   The switch also have a ATU (MAC-table) violation
interrupt, perhaps that might tell you something?

Another thing... An IXP425 specific change I had to make, was to disable
NPE_learning for the ixp400_eth driver.

 insmod ixp400_eth npe_learning=0

MODULE_PARM_DESC(npe_learning, "If non-zero, NPE MAC Address Learning &
Filtering feature will be enabled");

Perhaps the GIANFAR driver also has this kind of MAC address filtering?
