A new Flyspray task has been opened.  Details are below. 

User who did this - Perry (pmelange) 

Attached to Project - OpenWrt/LEDE Project
Summary - qos-scripts do not "add" the ifb interface before setting it to "up"
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - openwrt-21.02
Due in Version - Undecided
Due Date - Undecided
Details - This is device agnostic and applies to the master branch and openwrt-21.02.

Reproducible by setting up /etc/config/qos to a certain $IFACE and running the following command:

/usr/lib/qos/generate.sh interface $IFACE | sh -x

The error looks like this:

+ ip link set ifb0 up
+ tc qdisc del dev ifb0 root
+ tc qdisc add dev ifb0 root handle 1: hfsc default 30
Cannot find device "ifb0"
+ tc class add dev ifb0 parent 1: classid 1:1 hfsc sc rate 15000kbit ul rate 15000kbit
Cannot find device "ifb0"

PR #4092 has a proposed fix in it.
