[dpdk-dev] [PATCH] app/testpmd: refine xstats show

[Jianfeng Tan <jianfeng.tan@intel.com>]

When using "show port xstats all" command to show xstats, the output
is usually too long to obtain what you really want, expecially when
multi-queue is enabled.

This patch refines this situation by skipping showing those with value
of zero.
