[dpdk-stable] request backporting some patches to 16.07.2

[John Daley (johndale)]

Hi,
For Enic PMD, these 3 seem to already be in the stable branch, so no issues:
>> net/enic: document how to configure vNIC parameters 
> >net/enic: fix crash on MTU update or Rx queue reconfigure
> >net/enic: fix multi-queue Rx performance

For this one, I submitted another patch yesterday to stable@ which was rebased on top of the 16.07 stable branch and should apply clean:
> >net/enic: fix Rx queue index when not using Rx scatter

Other than that, enic is good (at least for now ;)

Thanks for managing the branch!
