Following changes are needed:

Currently we are defining:
edpm_ovn_bridge_mappings: ['dpdk2:br-link2', 'dpdk1:br-link1']

So, there are 2 dpdk networks: dpdk1 and dpdk2

We should have in service-values.yaml

  ovn:
    ovnController:
      nicMappings:
datacentre: enp4s0 # CHANGEME
        dpdk1: ospbr
        dpdk2: ospbr

 
We shoud add network attachment for dpdk1, and dpdk2. Currently I do not see any file we could add it 
apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
labels:
osp/net: dpdk1
osp/net-attach-def-type: standard
name: dpdk1
namespace: openstack
spec:
config: |
{
"cniVersion": "0.3.1",
"name": "dpdk1",
"type": "bridge",
"bridge": "ospbr",
"ipam": {}
}
—
apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
labels:
osp/net: dpdk2
osp/net-attach-def-type: standard
name: dpdk2
namespace: openstack
spec:
config: |
{
"cniVersion": "0.3.1",
"name": "dpdk2",
"type": "bridge",
"bridge": "ospbr",
"ipam": {}
}

We should be able to modify networks attachments from  our jobs too!!

additionally we need to add required nova filters
