For 16.11, since XXV710 is not officially supported, so they are missing in document.
For 17.02 this will be updated. Thanks for remind.

Actually only XXV710 need this two lines, but base on firmware engineer's input,
this could be implemented in generic way since no impact for other i40e devices.
