Subject: [09/38] xen: netfront: explicitly generate arp_notify event after migration.

2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

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

commit 592970675c9522bde588b945388c7995c8b51328 upstream.

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