This an update of series that let guest and qemu to be co-operated to send
gratuitous packets when needed such as after migration, loadvm and continuing.
As it's hard for qemu to track the network configuration in guest such as
bondings, vlans or ipv6. So current gratuitous may not work under those
situations.
The series first introduce a model specific function in order to let nic models
to use a device specific way to announce the link presence. With this,
virtio-net backend were modified to notify the guest (through config update
interrupt) and let guest send the gratuitous packet when needed.
