Great! In reading about this feature (thanks to your response), it looks
like the controller needs to present a connection id to OVS, which it will
only do if it supports the "NXT_SET_CONTROLLER_ID Nicira extension". Anyone
by chance know if this extension is something Opendaylight supports? If
not, no worries, I can ping their mailing list about it.

Thanks for the quick reply Ben!
