[libvirt] [PATCH 0/4] util: Fixing libvirt errors on cavium/thunder-nicvf

[Radoslaw Biernacki]

ThunderX is Cavium SoC. This platform contain SRIOV NIC.
Unlike other commonly known network devices it does not have VF functionality
duplicated in its PF. PF is purely management device (on HW level).

This creates several problems with existing libvirt code as in many places
libvirt assumes that each VF netdev has PF netdev assigned. 

This patch series trying to address issues which can be easily fixed.
(mostly bug fixes found while working on full featured solution)

First patch in series is most important as it allows to unblock the netdev
detection and use <hostdev> on this platform.
