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.
