    PCI-PT configuration when SR-IOV is not available (stx 7.0, stx8, ds7)

    There is a known limitation [1] and NICs that do not support SR-IOV
    require a different procedure [2] when configuring PCI-PT.

    This change adds a note on checking SR-IOV support for the target NIC,
    when configuring PCI-Passthrough for it, and adds the necessary
    steps for the configuration to work properly whit this type of NIC.

    For completeness, it also duplicates the PCI-PT example for when
    configuring PCI SRIOV Ethernet Interfaces, with the necessary
    changes to the procedure.
