Subject: [PATCH 0/2] Intel IFC VF driver for VDPA

Hi all:
  This series intends to introduce Intel IFC VF NIC driver for Vhost
Data Plane Acceleration(VDPA).

Here comes two main parts, one is ifcvf_base layer, which handles
hardware operations. The other is ifcvf_main layer handles VF
initialization, configuration and removal, which depends on
and complys to:
virtio_mdev https://lkml.org/lkml/2019/10/30/62 
vhost_mdev https://lkml.org/lkml/2019/10/31/440

This patchset passed netperf tests.

This is RFC V2, plese help review.

Changes from V1:
using le32_to_cpu() to convert PCI capabilities.
some set /get  operations will sync with the hardware, eg get_status
and get_generation.
remove feature bit VHOST_F_LOG_ALL, add VIRTIO_F_ORDERED_PLATFORM
add get/set_config functions.
split mdev type group into mdev_type_group_virtio and mdev_type_group_vhost
add ifcvf_mdev_get_mdev_features()
coding stype changes.
