[Qemu-devel] [PATCH v3 9/9] tests: Add a test for qemu self announcements

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

We now expose qemu_announce_self through QMP and HMP.  Add a test
with some very basic packet validation (make sure we get a RARP).
