Getting a new kernel version stable is kind of a long, hard effort,

Wanted to convince ubnt that there was value in fq_codel. They only just
released v1.4.1 with 3.4 (a huge jump forward from their last
release), the prospect of another 3 year jump nonplussed them.
Besides the openwrt version is already at 3.10, and I was curious as to
being able to compare 3.4 vs 3.x, and how another OS implements QoS.
(they have a cisco IOS like interface that appears to be written in Perl)
