XXV710 is 25G device, and support added in 16.11 (please correct me if
this is wrong.), but I can't find any DPDK documentation for this device.

Can you please add some documentation, at least to
http://dpdk.org/doc/nics and http://dpdk.org/doc/guides/nics/i40e.html
in a different patch?

> not support auto link update.

Can you please add more details that why we can remove the limitation now?

And these changes look like called for all device types, just to double
check, are these 25G specific?

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.

Ok, will update in v2.

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.

If officially will be added on 17.02, can you please update release
notes too, to announce new device support?
