Did you try to update tc to the latest commit in github.com/dtaht/tc-adv?
Your output suggests that the tc you are using doesn't understand some of the options.
Could you update tc to the latest commit from the above repo and try again?

Full output is in the file attached.

I discovered Cake works on commit 2b1c631, with linux-image-4.16.0-2-amd64. Then $TC -s qdisc outputs:
qdisc cake 8001: root refcnt 6 bandwidth 850Kbit (?diffserv?) dual-srchost rtt 100.0ms noatm overhead 18 total_overhead 18 hard_header_len 0 mpu 64

I will look for the commit between 2b1c631 and 8da93e1 that stops traffic.

Hello,

The computer on which I use Cake was upgraded to Debian
linux-image-4.16.0-2-amd64 and networking stopped working.

I load Cake with:

export TC=~/local/src/iproute2-cake-next/tc/tc
$TC qdisc add dev enp4s0 root cake bandwidth 850Kbit docsis nat \
dual-srchost ack-filter

Then network traffic appears to stop. I have tested with Cake/Cobalt
revisions 6f7e5af and 8da93e1.

Can anyone give hints on how to troubleshoot this?

What is the output of $TC -s qdisc?
