Codel is a new AQM algorithm and RED replacement designed by
Kathie Nichols and Van Jacobson, and published in ACM queue:

http://queue.acm.org/detail.cfm?id=2209336

Codel stands for "Controlled Delay", and needs no knobs in the
general case, twiddled, for optimum results. It aims for 5ms of
delay, at most, when in use.

Additionally,

fq_codel (by eric dumazet) builds on codel to provide fair queuing
superior to what could be had with SFQ, and drop behavior saner
than RED, BLUE, or choke.

These patches are backported from net-next and are known to work
on Linux 3.3.4 and later.

Includes updates to codel for better portability and speed
