[dpdk-dev] [PATCH v8 0/2] guide to debug and troubleshoot.

[Vipin Varghese <vipin.varghese@intel.com>]

The patch series adds a how-to guide for debugging and
troubleshooting tips.

Motivation
==========

DPDK proc-info tool is been enhanced to accommodate the debug information
for the port, traffic manager crypto, ring and mempool contents. With these
additional information, it becomes easy to analyze issues and performance
variance.

But applications are designed based on the target platform, workload, poll
mode drivers, and multi-process. This raises variance in debugging and
collecting data. Hence attempt of patch series is identified such symptoms
and share step by step guide to cover the cases.

Not all possible cases could be covered in a single attempt. But with
feedback and support from the community, this can be expanded.


Status
======

Reviews and changes accommodated. ACK received for documentation and SVG
files.
