How to use CAKE and Netem on the same interface?

Hello,

For some reason, I want to use CAKE to prioritize traffic and Netem to add loss on the same eth0 interface. However, when I add Netem I get the following error:

root@OpenWrt:~# tc qdisc add dev eth0 handle 1: root cake diffserv8
root@OpenWrt:~#
root@OpenWrt:~# tc qdisc
qdisc noqueue 0: dev lo root refcnt 2

RTNETLINK answers: Not supported

I saw a thread with a similar topic but it was created 3 years ago. Is there currently a way for me to use both CAKE and Netem on the same interface?

Thanks in advance.
