On http://www.bufferbloat.net/projects/codel/wiki/CakeTechnical, it
says that the hash used by fq_codel had various issues and that "we
have also found that the hash function fq_codel relies on is
suboptimal."  I believe that fq_codel uses the Jenkins hash like many
other parts of linux.  What was suboptimal about it?  The page notes
the birthday problem but was there anything else?
