With availability of switchdev model in linux, it is possible to capture
stats for SR-IOV device with interface_type as 'hostdev' provided device
supports VF represontor in switchdev mode[1] on host.

These stats are supported by adding helper APIs for getting/verifying VF
representor name based on PCI Bus:Device:Function information in domains
'hostdev' structure and querying required net sysfs directory and file
entries on host according to switchdev model. These helper APIs are then
used in qemu/conf to get the interface stats for VF representor on host
of pci SR-IOV device.
