The Intel VF section in the NIC guide document had descriptions of the
various drivers at a very deep level of the document hierarchy. Improve
the structure of the doc by giving those per-driver subsections their
own top-level section. Also create a new top-level section for details
of hypervisor use of VFs.

Intel® Ethernet Adaptive Virtual Function

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Adaptive Virtual Function (IAVF) is a SR-IOV Virtual Function with the same
device id (8086:1889) on different Intel Ethernet Controller.
IAVF Driver is VF driver which supports for all future Intel devices without
requiring a VM update. And since this happens to be an adaptive VF driver,
every new drop of the VF driver would add more and more advanced features that
can be turned on in the VM if the underlying HW device supports those
