[PATCH] [PATCH v5] app/testpmd: fix segfault in secondary process by monitoring primary

[Khadem Ullah]

Hi Stephen,

Many thanks for the fix and for the suggestion that the secondary should exit 
immediately without attempting any cleanups once it detects the primary has exited.

I completely agree. I’ll supersede this patch with a new version that incorporates 
both of our changes.

Best regards,
Khadem
