parentipv6: When we droped a packet, we should return NET_RX_DROP instead of 0 (diff)
pkt_sched: Fix locking of qdisc_root with qdisc_root_sleeping_lock()
Use qdisc_root_sleeping_lock() instead of qdisc_root_lock() where appropriate. The only difference is while dev is deactivated, when currently we can use a sleeping qdisc with the lock of noop_qdisc. This shouldn't be dangerous since after deactivation root lock could be used only by gen_estimator code, but looks wrong anyway.
