qdisc cake 8001: dev enp4s0 root refcnt 6 autorate_ingress (?diffserv?) dual-srchost ack-filter noatm overhead 18 total_overhead 18 hard_header_len 0 mpu 1

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
  Sent 7497015 bytes 130570 pkt (dropped 0, overlimits 5129 requeues 0)
  backlog 0b 0p requeues 0

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?
