Such experiments were carried out during 2.1. They showed that it is useless,
if not harmful. A prioritization has a meaning when you have a finite resource.
Shortly, backlog is not a queue. Backlog is serializer splitting hardware
irqs and networking process. This queue _cannot_ overflow.
When it overflows yet, machine has no time to prioritize anything,
rather it has to fight for life. 8)
