Re: [dpdk-dev] [PATCH 0/5] vmxnet3 pmd fixes/improvement

["Cao, Waterman" <waterman.cao@intel.com>]

Hi Thomas,

	Yes. Xiaonan just want to confirm if yong's patch doesn't impact original functionality and regression test cases under VMware.
	Xiaonan will check with yong and see if we can add some test in the regression to new changes.

	Waterman
