This makes little sense really. Otherwise everything would be in .h
files.
include/net/codel.h is an include file because both codel and fq_codel
use a common template for codel_dequeue() in fast path.
But net/mac80211/fq.h is included once, so should be a .c
Certainly all the code in control plan is not fast path and does not
deserve being duplicated.
