What is your goal?

It gives you 8 times as much conntrack entries as you have
conntrack hash buckets.  Isn't 8 a nice number?  What number
would you prefer, and why?  The kernel has to derive ip_conntrack_max
SOMEHOW, and that's the way it does it now. There is another equally
arbitrary choice of ip_conntrack_htable_size, which is calculated
from the amount of memory in your machine. Again, the kernel has to do
SOMETHING in the absence of configuration information.
