Re: [libvirt] [PATCH 0/4 v3] macvtap: Support for sending port profile message for a SRIOV VF to its PF

This patch tries to fix getPhysFn in macvtap.c to get the physical function(PF) of the direct attach interface, if the interface is a SR-IOV VF. It moves some of the sriov pci device handling code from node_device_driver to src/util/pci.[ch]. This patch series implements the following 01/4 - pci: Move some pci sriov helper code out of node device driver to util/pci 02/4 - pci: Add helper functions for sriov devices 03/4 - interface: Add functions to get sriov PF/VF relationship of a net interface 04/4 - macvtap: Fix getPhysfn to get the PF of a direct attach network interface

Changelog: ---------- v1: RFC patch introduced new functions to get PF/VF relationship of SRIOV net devices by comparing PF/VF sysfs device links. Also mentioned the existance of some related code in node_device_driver. The feedback was to move and use the node_device_driver code v2: Moves sriov get_physical_function and get_virtual_functions from node_device_driver to src/util/pci*. And reworks the rest of the patches around the new code. v3: Incorporated Stefan Berger's comments. Fixed indentation errors shown by 'make syntax-check'.
