kernel: add codel and fq_codel to generic 3.3 patch set (based on patch by Dave Täht)
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 SVN-Revision: 31756
