Supply the following if possible:

  • PCEngines APU2C4
  • OpenWrt SNAPSHOT, r12776-437eb41f23

Steps to reproduce:

  • install sqm-scripts
    root@OpenWrt:~# opkg install sqm-scripts
  • qdisc cake isn´t able to setup with tc
    root@OpenWrt:~# tc qdisc add dev eth0 root cake
    Error: NLA_F_NESTED is missing.

Also cake isn´t detected as available in sqm-scripts (/tmp/run/sqm/available_qdiscs/)!

fq_codel does work as expected.

root@OpenWrt:~# tc qdisc add dev eth0 root fq_codel

I've not seen this.. hmm. Please could you try r12793-fcd1401700 and be sure to update the package feed so sqm-scripts pulls in the correct kmod-sched-cake dependency.

I used the prebuilt snapshot builds and kmod-sched-cake was installed for my test.

Updated to latest snapshot build and cake does work as expected now.
Probably the snapshot kernel and kmods was out of sync before.
So this bug report could be closed, thanks.****
