Re: [dpdk-dev] Intel fortville not working with multi-segment

Today I got a ready environment, and tried the latest DPDK code (on master branch) on my environment, it works well.
So could you help to try the latest code (R2.0 +) on your environment again, to see if the issue is still there or not?

Regards,
Helin
