> 
> During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability register
> will be cleared. This can lead to issues when a VF is assigned to a VM because
> in these cases the VF driver receives no indication of the PF PCI error/reset
> and additionally it is incapable of restoring the cleared flag in the hypervisor
> configuration space without fully reinitializing the driver interrupt
> functionality.
> 
> Since the VF driver is unable to easily resolve this condition on its own,
> restore the VF MSI-X flag during the PF PCI reset handling.
