I prolly should have added comments there. prioidx carries the cgroup
ID on the hierarchy net_prio is attached to, so if nothing is
configured, the default value would be the ID of the root cgroup which
is always 1. For net_cls, the unconfigured default value is zero.
Will refresh the patch with comments.
