debloat runs on both std ubuntu/deb= ian systems and openwrt and turns
off offloads via ethtool, and trims = down

On ubuntu...

It is intended to run out of /etc/n= etwork/ifup.d, and as such does not
take command line arguments but en= vironmental parameters.

e.g.

IFACE=3Dwlan1 QMODEL=3Df= q_codel debloat

On openwrt/cerowrt it runs out of /etc/hotplug.d= /iface/00-debloat

There are tons of QMODEL options, see the bott= ommost portion of
"debloat" for the callbacks.


There = are various options, like QDEBUG=3D1, which dumps the commands fed
to = tc to stdout and a lot of bad-out-of-date documentation inside it.
It = started life as a wrapper around qfq and has grown rather
embarrassing= ly bloated over time.

One major bug is that it does not detect b= ridged interfaces presently.

The simple_qos.sh script relies on = it to set the tricky parameters
that it overrides.

> And= which queue should have ecn disabled?

in the simple_qos.sh scri= pt I have been disabling ecn on egress
universally. It's on on ingress= .

Note that this script is intended for a rate limited ethernet = device, not wifi.

Of late, for wifi, I have been disabling ecn o= n wifi on the vo queue
and the background queue. There are various var= iants of the debloat
script (for wifi, ethernet, and various variants = of codel, Xfq_codel,
and QFQ) in play at the moment.
