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.

It's good that you pass tags from our e1000 ML here, however please copy them verbatim from the response body (instead of copying that from whatever MS outlook displays as sender). (Wojtek's RB was fine in previous version of the patch)

You should never add such tags when not explicitly provided by reviewer.
