The number of nfnetlink subsystem is small and it will remain small
along time I guess. I would not spend time on such optimization.
Anyway, the static subsys ID number is a good thing IMO.
The floating genetlink ID allows to have out-of-tree subsystems, which
is something that I don't like that. Moreover, you have to send an
initial message to resolve the ID number and subscribe to possible
changes in it.
