I don't want to perpetuate the "please carefully set your command line" habit.
This feature is added through a C API, with documentation and flagged
as experimental, it should be enough.
How about moving the mp disable in rte_thread_register() as a separate API?
Then a developer must call rte_mp_disable() before attempting
rte_thread_register().
That would be equivalent to --proc-type=single.
Why not convert lcore-allow into an API?
This would force us to put something in the init so that external
users see how the application has been started and adjust the
secondary commandline.
On the other hand, rte_mp_disable() is easy to do with my current v4 +
I am running out of time for rc1.
We can still revisit this experimental API.
