| |
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.
