Hi Wenzhuo, Beilei, Bernard
I need testpmd app maintainers' comment :
Do you prefer the simple solution in this patch or Stephen's comprehensive
and generic solution(which will modify librte_cmdline, testpmd (and maybe
rte_exit()))?
So I can continue resolving the defect.
Thanks!

Hi Stephen,
Do you mean this solution?
1. support atexit() in librte_eal, other component can use it to register a
function to be called when rte_exit() is called.
2. in librte_cmdline, use atexit() to register a function to release resource
I am looking forward to more comments from other maintainers, since this
solution will modify librte_eal and librte_cmdline, but not just testpmd app.

Sounds like a more generic problem with rte_exit and librte_cmdline.
Would it better to fix it in librte_cmdline by adding an atexit() handler.
