From: Ian Campbell <Ian.Campbell@citrix.com>

commit 592970675c9522bde588b945388c7995c8b51328 upstream.

Use newly introduced netif_notify_peers() method to ensure a gratuitous ARP is
generated after a migration.

Hi Greg,

Looks like I forgot to request this for 2.6.32 too, could you queue it
up there as well?

It depends on the previous patch in this series (arp_notify: allow
drivers to explicitly request a notification event.).

Thanks,
Ian.
