    Subject[044/272] staging: hv: Enable sending GARP packet after live migration
    2.6.37-stable review patch.  If anyone has any objections, please let us know.

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

    From: Haiyang Zhang <haiyangz@microsoft.com>

    commit 7c161d0b900ea9bd9fc5ea5d3fa9916e9eb0dd88 upstream.

    The hv_netvsc gets RNDIS_STATUS_MEDIA_CONNECT event after the VM
    is live migrated. Adding call to netif_notify_peers() for this event
    to send GARP (Gratuitous ARP) to notify network peers. Otherwise,
    the VM's network connection may stop after a live migration.

    This patch should also be applied to stable kernel 2.6.32 and later.
