hi, We are currently trying to deploy ovs-dpdk in kolla-ansible pike branch. we have made changes in globals.yml as:

ovs_datapath: "netdev"
enable_ovs_dpdk: yes
enable_openvswitch: yes
tunnel_interface: "dpdk_bridge"
neutron_bridge_name: "dpdk_bridge"

however the deployment fails in neutron role:

fatal: [172.16.141.20]: FAILED! => {"failed": true, "msg": "{{ hostvars[inventory_hostname]['ansible_' + tunnel_interface]['ipv4']['address'] }}: 'dict object' has no attribute u'ansible_dpdk_bridge'"}
fatal: [172.16.141.21]: FAILED! => {"failed": true, "msg": "{{ hostvars[inventory_hostname]['ansible_' + tunnel_interface]['ipv4']['address'] }}: 'dict object' has no attribute u'ansible_dpdk_bridge'"}

I was under assumption dpdk_bridge would be created during deployemt by the ansible plays itself. Is it not the case

PS: my globals.yml: http://paste.openstack.org/show/666903/ output to ip a: http://paste.openstack.org/show/666904/

Any help would be much appreciated
