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

[Dr. David Alan Gilbert (git)]

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

Hi,
  This is a reworking of a few sets of patches from 2017
that were put together by myself, Germano and Vlad that make
the network announce system more flexible.

  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:
