[Qemu-devel] [PATCH V7 2/5] net: announce self after vm is started

[Jason Wang <jasowang@redhat.com>]

Since we may want to send garp by guest if guest driver is capable of it. We
need trigger this event after vm is started. So this patch do this when the
state is changing from RUN_STATE_PRELAUNCH_MIGRATE to RUN_STATE_RUNINNG.
