[libvirt] [PATCH v4 0/6] Support network stats for VF representor interface

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 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 of pci SR-IOV device. V4 includes changes based on feedback received for v3 patchset. Added new generic API for linux is added to fetch stats from /proc/net/dev which will be used by tap and hostdev devices. Also introduced new API to retrieve net def from given domain based on the given hostdev which supports network.
