net_sched: sfq: always randomize hash perturbation SFQ q->perturbation is used in sfq_hash() as an input to Jenkins hash. We currently randomize this 32bit value only if a perturbation timer is setup. Its much better to always initialize it to defeat attackers, or else they can predict very well what kind of packets they have to forge to hit a particular flow.
