====================
40GbE Intel Wired LAN Driver Updates 2017-06-01

This series contains updates to i40e, i40evf and the "new" AVF virtchnl.

This is the introduction of the Intel(R) Ethernet Adaptive Virtual
Function driver code and device ID, as presented at the NetDEV 1.2
conference in 2016.
http://netdevconf.org/1.2/session.html?anjali-singhai



The idea is to convert the interface between the i40evf driver
and the parent i40e PF driver to be generic, as the i40evf driver
should in the future be able to run on top of other Intel PF
drivers, and negotiate any features beyond a "base expected" set.

This file describes the i40evf Linux* Base Driver for the Intel(R) XL710

X710 Virtual Function.

This file describes the i40evf Linux* Base Driver.



The i40evf driver supports XL710 and X710 virtual function devices that

can only be activated on kernels with CONFIG_PCI_IOV enabled.

The i40evf driver supports the below mentioned virtual function

devices and can only be activated on kernels running the i40e or

newer Physical Function (PF) driver compiled with CONFIG_PCI_IOV.

The i40evf driver requires CONFIG_PCI_MSI to be enabled.



The guest OS loading the i40evf driver must support MSI-X interrupts.



Supported Hardware

==================

Intel XL710 X710 Virtual Function

Intel Ethernet Adaptive Virtual Function

Intel X722 Virtual Function
