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.
