Subject: [Patch net 0/2] net_sched: Fix HFSC qlen/backlog accounting bug and add selftest

This series addresses a long-standing bug in the HFSC qdisc where queue length
and backlog accounting could become inconsistent if a packet is dropped during
a peek-induced dequeue operation, and adds a corresponding selftest to tc-testing.
