Description of problem:
I have second interface (eth1) which I use to communicate with compute nodes. I told to packstack to use it as OVS tunnel:
CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-tun:eth1
It correctly set eth1 as type=OVSPort and configure the bridge. But if I need to rerun packstack again, packstack fails with
ERROR : Error appeared during Puppet run: 209.132.184.9_neutron.pp
Error: Local ip for ovs agent must be set when tunneling is enabled at /var/tmp/packstack/ad2105c5cc1e46388c4276f82f6f1957/modules/neutron/manifests/agents/ml2/ovs.pp:107 on node fed-cloud09.cloud.fedoraproject.org

It is because that it expect that eth1 is up (which is) and have ip addr assigned (which is not, because it is OVSPort.

If I need to rerun packstack now, I have to either reprovision machine or wipe openstack, which may leave ovsswitch leftovers, which several times cut my networking.

Version-Release number of selected component (if applicable):
openstack-packstack-puppet-2014.1.1-0.28.dev1238.el7.noarch
openstack-packstack-2014.1.1-0.28.dev1238.el7.noarch

How reproducible:
deterministic

Steps to Reproduce:
1. configure eth0 as external network, and eth1 as internal and set it as ovs tunnel
2. run packstack once
3. run packstack second time

Actual results:
Error: Local ip for ovs agent must be set when tunneling is enabled at /var/tmp/packstack/ad2105c5cc1e46388c4276f82f6f1957/modules/neutron/manifests/agents/ml2/ovs.pp:107 on node fed-cloud09.cloud.fedoraproject.org

Expected results:
No changes in networking, when networking configuration already match final state.
