Configuring TP-Link TL-WR740N v4.27 for OpenFlow and OpenWRT

In this post, I detailed the configurations required for TP-Link TL-WR740N v4.27 to work with OpenFlow. Basically four files needs to be changed and I have included below the configurations, which worked for me.

This example configuration is considering you would like to use WAN port as management port and LAN ports as OpenFlow ports. In such you will have to make sure controller is running in same network as WAN port is configured.
