HTB dequeueing in pairs fixed

Linux Advanced Routing and Traffic Control

I posted earlier when I noticed that htb was releasing packets in pairs, even though my burst/quantums were 1 pkt.

To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c .

This gives a noticable gain in upstream worst case latency, for me with 256kbit/s up I used to see +90 sometimes, now it's +45. For the many who have 128 up it should limit them to +90 rather than +180.

Andy.
