Public bug reported: [SRU justification]
== Impact The kernel dropped support for the CBQ (class based queuing) qdisc support in kernel version 6.3 051d44209842 (net/sched: Retire CBQ qdisc, 2023-02-14) This was reflected in iproute2 upstream in v6.6.0. But noble shipped with v6.1.0. So the man page and help of tc still mention cbq. Any attempts to use it result in a failure. This also breaks the DEP-8 tests as those attempt to make use of cbq. This affects only 24.04 Noble as later series already have a fixed iproute2 version and previous series still have CBQ support (except jammy:linux-hwe-6.8). == Fix Backport the upstream iproute2 patch which drops support for qbf. >From 07ba0af3fee132eddc1c2eab643ff4910181c993 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger <[email protected]> Date: Mon, 30 Oct 2023 11:10:18 -0700 Subject: [PATCH] tc: remove support for CBQ == Testing 1.
