Subject: iproute2: Using HFSC-qdisc causes WARNING-messages and stack-traces in syslog

Package: iproute2
Version: 4.16.0-4
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
	Upgrading to the latest kernel 4.16.0-4. With previous versions
	of kernel and iproute2-packages these issues did not occur.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?
	I applied the following script to my interfaces:

	tc qdisc add dev enp6s0f0 root handle 1: hfsc default 3
	tc class add dev enp6s0f0 parent 1: classid 1:1 hfsc ls rate
	100000kbit ul rate 100000kbit
	tc class add dev enp6s0f0 parent 1:1 classid 1:2 hfsc ls rate
	75000kbit
	tc class add dev enp6s0f0 parent 1:1 classid 1:3 hfsc ls rate
	20000kbit
	tc class add dev enp6s0f0 parent 1:1 classid 1:4 hfsc ls rate
	5000kbit
	tc qdisc add dev enp6s0f0 parent 1:2 handle 2: fq_codel noecn
	tc qdisc add dev enp6s0f0 parent 1:3 handle 3: fq_codel noecn
	tc qdisc add dev enp6s0f0 parent 1:4 handle 4: fq_codel noecn

	tc qdisc add dev enp6s0f1 root handle 1: hfsc default 2
	tc class add dev enp6s0f1 parent 1: classid 1:1 hfsc ls rate
	1000mbit ul rate 1000mbit
	tc class add dev enp6s0f1 parent 1:1 classid 1:2 hfsc ls rate
	910000kbit ul rate 910000kbit
	tc class add dev enp6s0f1 parent 1:1 classid 1:3 hfsc ls rate
	900mbit
	tc qdisc add dev enp6s0f1 parent 1:2 handle 2: fq_codel noecn
	tc qdisc add dev enp6s0f1 parent 1:3 handle 3: fq_codel noecn


   * What was the outcome of this action?
   	The script completed and the qdiscs were added. However, the
	following entries are now being seen every few minutes in
	syslog:

   * What outcome did you expect instead?
   	I expected the hfsc and fq-codel to continue working without any
	issues.
