Subject: [PATCH 0/2] HTB scheduler HTB_HYSTERESIS modifications
Date: Tuesday, June 3, 2008 - 10:03 am

This patch set modifies the HTB schedulers hysteresis mode.  The HTB
hysteresis is a hack to reduce the CPU load, it introduces significant
jitter, enough to disturbe VoIP quality on e.g. ADSL.

The first patch changes HTB_HYSTERESIS to default off.

The second patch Change HTB_HYSTERESIS to a runtime parameter
htb_hysteresis, adjustable via
sys/module/sch_htb/parameters/htb_hysteresis.

For details about my measurements see masters thesis
(http://www.adsl-optimizer.dk/thesis/), chapter 7, section 7.3.1,
page 69-70.
