valdisk:

wrt1200ac works OK with 4.19.108 kernel. eth1 is the upstream port, eth0 is the 4 local gigabit ports. dmesg reports:

Under the 5.4.48 kernel, eth1 doesn't show up, so no upstream connectivity.

This is expected with the change from swconfig to DSA.

valdisk:

Thanks for that info. Is there a relevant issue to track so I know when it's at least plausibly worth trying again? (I don't mind testing bleeding-edge software, but it's not worth the effort until it gets to "needs sysadmin to apply crowbar to the config" levels of working...)

It works now, but your have to adapt you config for DSA. [[https://bugs.openwrt.org/index.php?do=details&task_id=3171&order=id&sort=desc|FS3171]], or [[https://github.com//pull/2942|PR2942]] for a more complex vlan setup, also the forum has more examples.
