We use the branch rdkb-2022q1-dunfell.
After startup, eth1 is not up and only wlan0 in the bridge.

root@RaspberryPi-Gateway:/usr/sbin# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000000000000 no
br106 8000.000000000000 no
br403 8000.000000000000 no
brebhaul 8000.000000000000 no
brlan0 8000.e45f01a73a9a no wlan0
But we can add eth1 to bridge manually.
The question is which module should be response to start the eth1 and add eth1 to brlan0?
What is the normal scenario?
