I still think it is not a good idea to change default number of mbufs.
8K is not that much: 1 core with 4 ports, or 1 port over 4 cores,
and user might start to see unexpected failures.
Now you added an option to allow user define number of mbufs in the app,
which is a good thing, but default one I think should remain the same
(to avoid any unexpected failures).
