[Cake] Failure with commit 8da93e1

[Kristjan Onu]

  > What is the output of $TC -s qdisc?

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
   Sent 0 bytes 0 pkt (dropped 4, overlimits 0 requeues 0)
   backlog 0b 0p requeues 0

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.
