In order to properly restore the original state of an SRIOV VF when we're finished with it, we need to save the MAC address of the VF itself (not just the admin MAC address for the VF that is stored in the PF). But that can only be done when the VF is still bound to the host's netdev driver, and we have always done the saving of device config after the VF is already bound to vfio-pci. This patch prepares us for adding a save of the VF's MAC by calling the function that saves netconfig earlier in the device preparation, before we've unbound it from the host netdev driver.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
