[dpdk-dev] [PATCH v4] app/pdump: add pudmp exits with primary support.

[Varghese, Vipin]

Thanks for the patch work with rte_eal_alaram. But I am not able to find 

1. the documentation update.
2. cover letter.
3. for signal SIGINT, set for ` rte_eal_alarm_cancel`. 

Can you share a new patch as v5 with these changes?

Thanks
Vipin Varghese
