3.16-stable review patch. If anyone has any objections, please let me know.

From: Julian Anastasov <ja@ssi.bg>
commit eb90b0c734ad793d5f5bf230a9e9a4dcc48df8aa upstream.
commit fc604767613b6d2036cdc35b660bc39451040a47 ("ipvs: changes for local real server") from 2.6.37 introduced DNAT support to local real server but the IPv6 LOCAL_OUT handler ip_vs_local_reply6() is registered incorrectly as IPv4 hook causing any outgoing IPv4 traffic to be dropped depending on the IP header values.
Chris tracked down the problem to CONFIG_IP_VS_IPV6=y Bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349768
