Stephen, thank you for your comment. You have asked in earlier request to try using hwloc library.
I have mentioned at least till last year popular distros were still using older version for hwloc and I will recheck if it has changed.

This I assumed for mitigating the `sysfs` and bringing in `OS` portability.

Now I really confused, for any application or end user which want to use the right set of lcores for performance DPDK provides abstraction and ease of use.
Maybe I am misreading the above idea, so let me back off a bit and share version-2 of the RFC.
