Please do try a newer kernel. 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,
