NOTE(melwitt): This is the combination of two commits, the workaround
config option and a followup change to add a note that enabling the
workaround will cause the guest domain to be considered tainted by
libvirt.
This patch adds a workaround that can be enabled
to send an announce_self QEMU monitor command
post live-migration to send out RARP frames
that was lost due to port binding or flows not
being installed.
Please note that this makes marks the domain
in libvirt as tainted.
