Subject: [PATCH 00/10] SFQ: backport some features from ESFQ (try 3)

Patchset try 2 addresses the review by Michael Buesch.
Patchset try 3 addresses the review by Patrick McHardy.

The first 7 patches in this series resemble the corresponding 7 patches
I sent previously. There aren't any major changes--just modifications
to address errors noticed in review and slight reorganizations to make
the next patches easier.

Patches 8-10 implement parameter passing via nested compat attributes.
This is necessary for using 'tc qdisc change' to disable perturbation.
The rest of the parameters were added for consistency.

Iproute2 patches will follow shortly.

The following is the original patch text.

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.

Thanks for your consideration,
Corey
