From: "Sexton, Rory" <rory.sex...@intel.com>
Need a way to convert a vf id to a pf id on the host so as to query the pf
for relevant statistics which are used for the frequency changes in the
vm_power_manager app. Used when profiles are passed down from the guest
to the host, allowing the host to map the vfs to pfs.
