Hi all,

This series intends to implement driver module for Intel IFC VF NIC,
which can do Vhost Data Plane Acceleration(VDPA) by offloading
dataplane traffic to hardware.

This series depends on and complies to:
virtio_mdev V13 https://lkml.org/lkml/2019/11/18/261
vhost_mdev V7 https://lkml.org/lkml/2019/11/18/1068

There comes mainly two parts of the code:
(1) ifcvf_main layer handles probe / remove / mdev operations,
implemented struct mdev_virtio_ops to support virtio_mdev
and vhost_mdev, and other supportive functions.

(2) ifcvf_base layer talks directly to the hardware, which support
the ifcvf_main layer.

  IFC VF initialization functions
  This commit adds functions to support virtio_mdev and vhost_mdev
