Thank you for the responses. I will try this out on a newer kernel report back.

There have been many fixes to i40e in the last years that likely haven't made it back into whatever kernel this 3.10.0-based kernel is. It is a CentOS kernel.. so perhaps you could also try a newer release of CentOS instead, (RedHat does a pretty good job backporting fixes so perhaps something newer has the more recent fixes in it) Thanks, Jake
