  The patch series enhances application to support pdump capture to run
on unique cores.

Motivation
==========

DPDK pdump capture tool currently runs as secondary on the default core 0.
For all --pdump, core 0 iterates and capture packets. This leads to drops
and delay in the capture. This introduces skew in result and performance
bottleneck.

In order to allow --pdump to unique cores, the pdump application has to be
support multi-core in EAL arguments and each --pdump has to be mapped to
unique cores.

Status
======

 - Default c_flag option is removed.
 - with option --multi, the application can run on unique cores.

Change Log:
===========
