Florian,
I have managed to use DSA driver and was able detect both internal and
external switches. However, I only get packets flowing only through the
internal switch. I have used the ip & bridge commands to setup the vlan
101 & 102 for lan and wan respectively.
VLAN101 = lan1 lan2 lan3 lan4 lan5 lan6 lan7 lan8 eth0.101
VLAN102 = wan eth0.102
Reading configs from the factory firmware, I'm sure that sw0port0 and
sw1port8 are connected. Excerpt from the same:
port_numbers=0 2 4 2 1 3 1 3
port_switch_id=1 1 1 0 1 1 0 0
port_names=port0 port1 port2 port3 port4 port5 port6 port7
cpu_port_number=5 7 8
cpu_port_switch_id=0 0 0
hidden_port_numbers=0 8
hidden_port_switch_id=0 1
Below is my updated device tree.
Thanks,
Vivek
