pkt_sched: HTB scheduler, change default hysteresis mode to off.
The HTB hysteresis mode reduce the CPU load, but at the
cost of scheduling accuracy.
On ADSL links (512 kbit/s upstream), this inaccuracy introduce
significant jitter, enought to disturbe VoIP. For details see my
masters thesis (http://www.adsl-optimizer.dk/thesis/), chapter 7,
section 7.3.1, pp 69-70.
