I mean the failsafe kicks in long before the network config and vlan setup is done. I've tested this with a board using the xrx200 in-SoC switch and a board using a RTL8306G switch. In both cases it wasn't necessary to turn off the vlans since they had not yet been configured. Mathias

I had changed the case statement to only consists of a default case, to make obvious how to add a different config for a specific board. But in the end I dropped the whole case since it was just unused code.

But I don't like the idea of adding a default switch config for boards where it isn't strictly required. Especially in a failsafe script. The more code we add, the more likely is a breakage or an unconsidered side-effect of a change. Since I don't have any of the affected danube boards, adding support for this special case to the patch is out of scope for me. I don't like to add untested code. Mathias

So far the network in failsafe is setup only for one board. Use the eth0 interface as lan interface for all boards for now. If a board has its lan interface(s) on another eth, a special handling based on the board name can be added.
