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.
