Re: [dts] [PATCH V1] add test suite vhost_pmd_xstats

["Liu, Yong" <yong.liu@intel.com>]

Gang, stability test will cause too much time for running. You can limit 
the duration to few minutes and let's merge this suite first.
Then we need one solution for distribute different kinds of cases. It'll 
be next step.

Thanks,
Marvin
