This series enabled Intel FGPA SmartNIC C5000X-PL virtio-net for vDPA.

vDPA requires VIRTIO_F_ACCESS_PLATFORM as a must,
this series verify this feature bit when set features.

Changes from V3:
checks features to set in verify_min_features(Jason)
deduce VIRTIO device ID from pdev ids in get_device_id(Jason)

Changes from V2:
verify VIRTIO_F_ACCESS_PLATFORM when set features(Jason)

Changes from V1:
remove version number string(Leon)
add new device ids and remove original device ids
in separate patches(Jason)


Zhu Lingshan (7):
  vDPA/ifcvf: get_vendor_id returns a device specific vendor id
  vDPA/ifcvf: enable Intel C5000X-PL virtio-net for vDPA
  vDPA/ifcvf: rename original IFCVF dev ids to N3000 ids
  vDPA/ifcvf: remove the version number string
  vDPA/ifcvf: fetch device feature bits when probe
  vDPA/ifcvf: verify mandatory feature bits for vDPA
  vDPA/ifcvf: deduce VIRTIO device ID from pdev ids
