[libvirt] [PATCH 14/16] Rename APIs for dealing with virtual/physical functions



From: "Daniel P. Berrange" <berrange redhat com>

Rename ifaceIsVirtualFunction to virNetDevIsVirtualFunction,
ifaceGetVirtualFunctionIndex to virNetDevGetVirtualFunctionIndex
and ifaceGetPhysicalFunction to virNetDevGetPhysicalFunction

* src/util/interface.c, src/util/interface.h: Rename APIs
* src/util/virnetdevvportprofile.c: Update for API rename
