[Qemu-devel] [PATCH v5 0/9] Network announce changes

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <address@hidden>

  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:
