The observable issue were that interface would drop all TX packets, because it had assigned the qdisc noop. This turned out the be a NIC driver bug, that would only get triggered when using sysctl net/core/default_qdisc=fq_codel. It was non-trivial to find out[1] this was driver related. Thus, this patchset besides fixing the driver bug, also helps end-user identify the issue.
