--- Begin Message ---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.
