[SRU Justification]

== Impact

Subject: [PATCH] tc: remove dsmark qdisc

Backport this change into noble to fix ADT testing and correct the

== Testcase

1. Check "man tc" and "tc qdisc help" to not mention dsmark.
2. ADT tests should pass.

== Regression potential

Scripts might complain about missing dsmark support but trying to use
that type would have resulted in errors even before this change.
