I'm able to configure a logical switch on a HWVTEP, but ODL seems unable to correlate the configured and operational topology entries for the HWVTEP. So the logical switch is "created" rather than "updated", and the operational topology is unchanged.

so then when I create the termination point for the port/VLAN mapping to the logical switch ODL sends "named-uuid","LogicalSwitch_ls0" instead of "uuid","c0d53932-dd4b-46b3-8d7f-b3bbceacdf05" as expected by the switch.

I'm seeing this both with Boron-SR3 and with Carbon snapshot (with Carbon I also get an NPE).
