Hi,
Has anybody here work on this subject and update a newer patch?
Thanks in advance.

-----bellows are words from patch v7 ----
This series tries to let guest instead of qemu to send the gratuitous packets
after migration when guest is capable of doing this. This is needed since it's
impossible for qemu to keep track of all configurations (e.g 802.1Q) and mac
addresses (more than one mac address may be used by guest). So qemu can't build
gratuitous packets for all those configurations properly. The only solution is
let guest driver who knew all needed information to do this.
The series first introduces a new runstate which just tracks the state when the
migration is finished and guest is about to start. And then we can just trying
to notify the guest to send the GARP after changing from this state to
running. A model specific announcing method were also also introduced to let
each kinds of nic do its own notification. When there's no such method register
for the nic, the old style of sending RARP were kept. And the last two patches
implemented the virtio-net method of notification.
