Patch 620-net_sched-codel-do-not-defer-queue-length-update.patch is actually an ancient patch that somehow manage to be ported for 7 solid years. This comes from [1] where a fix patch was proposed. Nobody notice that the proposed patch was actually rejected upstream in favor of [2]. And the upstream fix patch is present in kernel from version 4.18. This means that we were actually fixing for a non existant bug and maybe introducing regression down the line. Drop the patch for good as we already have a fix for it in flace for a long time.
