This also includes the fix to sch_prio based on Patrick's patch. The sch->parent handle should contain the parent qdisc ID. When the qdisc is the root qdisc (TC_H_ROOT), the parent handle should be the value TC_H_ROOT. This fixes sch_api to set this correctly on qdisc_create() for both ingress and egress qdiscs. Change this check in prio_tune() so that only the root qdisc can be multiqueue-enabled; use sch->parent instead of sch->handle. -- PJ Waskiewicz
