Add NetClassVFPCIAddress method to FS that resolves the PCI BDF address of a SR-IOV Virtual Function by reading the sysfs virtfn symlink at /sys/class/net/<iface>/device/virtfn<vfIndex>. This enables callers to correlate VF network metrics with workloads that reference VFs by PCI address (e.g. OpenStack Nova, libvirt, DPDK). Signed-off-by: Anthony Harivel <[email protected]>
