[Dave Taht]

A couple questions worth answering in a faq:

A) Under what circumstances is cake a replacement for fq_codel?

B) When is fq_codel a better choice than cake?

When shaping or Diffserv prioritisation is required, or when flow hash collisions are likely to be problematic.

When none of the above apply, and a slight improvement in CPU and memory overhead is desirable.

fq_Codel is still useful if you need a traffic shaper with bandwidth
controls, like HFS. Maybe fq_Codel could be updated with "ways" like Cake,
to remove hash collisions.
