Subject: SFQ: backport some features from ESFQ (try 2)

Hello,

Patchset try 2 addresses the review by Michael Buesch.

This set of patches adds some of ESFQ's modifications to the original 
SFQ. Thus far, I have received support for this approach rather than for 
trying to get ESFQ included as a separate qdisc.

http://mailman.ds9a.nl/pipermail/lartc/2007q2/021056.html

My patches here implement "tc qdisc change", user-configurable depth 
(number of flows), and user-configurable divisor (for setting hash table 
size). I've left out the remaining ESFQ features (usage of jhash and 
different hashing methods) because Patrick McHardy intends to submit a 
patch that will supersede that functionality; see the URL above.

Default values remain the same, and SFQ's default behavior remains the 
same, so there should be no user disruption.

A patch for iproute2 is included after the end of the kernel patch series.

Thanks for your consideration,
Corey
