This setting defines the interface used for tenant network traffic using VXLAN or GRE. The benefit is that you separate management and tenant network traffic. If you leave it out, all traffic uses a single interface.

If your interface names are different on the compute and controller nodes, you could try to manually set the local_ipoption in openvswitch_agent.ini on both nodes. Or you disable predictable network interface naming on the nodes, so that they are called eth0 etc.
