    pci: Clarify SR-IOV ports vs direct passthrough ports
    
    This patch clarify for what type of ports
    detach/attach pci device is needed and for what type of
    port we just need pci request. To avoid confusion this
    patch introduce 2 type of ports list VNIC_TYPES_SRIOV
    and VNIC_TYPES_DIRECT_PASSTHROUGH. The VNIC_TYPES_SRIOV
    are ports which require pci request, while
    VNIC_TYPES_DIRECT_PASSTHROUGH  ports require pci device
    attach/detach from libvirt dom. VNIC_TYPES_DIRECT_PASSTHROUGH
    is subset of VNIC_TYPES_SRIOV.

Title:
  libvirt: Snapshot and resume does not work for instances with some SR-
  IOV ports

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  libvirt driver methods that are used for determining whether a port is
  an SR-IOV port do not check properly for all possible SR-IOV port
  types:

  https://github.com/openstack/nova/blob/f15d9a9693b19393fcde84cf4bc6f044d39ffdca/nova/virt/libvirt/driver.py#L3378

  should be checking for VNIC_TYPES_SRIOV instead.

  This affects snapshot and suspend/resume functionality provided by the
  libvirt driver, for instances using non-direct flavors of SR-IOV
