Confirmed on both ODL Helium SR2 and Brocade Vyatta Controller 1.1.1. Confirmed that behavior is the same if new port is up or down.
Steps to reproduce:
1. Connect OVS device up to ODL controller
2. dump flows for switch (in this case switch1)
3. add new port to switch
4. dump flows for switch - no flow installed for new port
5. disconnect/reconnect to ODL
6. dump flows for switch - new port will have default flow.
