[PATCH v3 3/3] qemu: Emit NIC_MAC_CHANGE event
From: Michal Privoznik <mprivozn(a)redhat.com>
So far, we only process NIC_RX_FILTER_CHANGED event when the
corresponding device has 'trustGuestRxFilters' enabled. And the
event is emitted only for virtio model. IOW, this is fairly
limited situation and other scenarios don't emit any event (e.g.
change of MAC address on a PCI passthrough device).
Resolves: https://issues.redhat.com/browse/RHEL-7035
