Firstly, it's parameterised, so that you can change the number
of packets and the gap between them; the number can be set to 0
to disable announce completely.
Secondly, you can force an announce by a qmp or hmp command at
any time. This is useful if you need the guest to do an announce
for a different reason; for example if the management layer
has just juggled some bonding configuration around.
The packet creation and timing also moves to net/ from migration/
The previous set was:
