As noted elsewhere, fq_codel is now the default qos system in openwrt
as of build 31761

http://buildbot.openwrt.org:8010/one_line_per_build

37 arches, 150 platforms, no waiting.

There are still a few patches left to land, and it doesn't turn it on
on the wireless or ethernet by default, although it should definitely
do so, in the case of the latter, and well, it helps a bit on
wireless, too, although major surgery on the stack remains to get it
right.

And codel + QFQ remains interesting.

I look forward to hearing about your results.
