[libvirt] [PATCH 4/4 v3] macvtap: Fix getPhysfn to get the PF of a direct attach network interface

From: Roopa Prabhu <roprabhu(a)cisco.com&gt; This patch renames getPhysfn to getPhysfnDev and adds code to get the Physical function and Virtual Function index of the direct attach linkdev (if the direct attach interface is a SRIOV VF). The idea is to send the port profile message to a PF if the direct attach interface is a SRIOV VF.
