Thanks for the clarification. A workaround for the issue is once remove the qdisc from the interface, i.e. `tc qdisc delete dev wg-kanamin ...`, then call `networkctl reconfigure wg-kanamin` or...

We have a test case for cake, and it works fine. Also, the .network file you provided in the above works fine. But, if a cake is partially configured, e.g....
