When we connect HW OF switch to controller, we observe controller sends feature request once, switch answers with feature reply and controller registers the switch, however after that controller re-sends feature request and after receiving features for second time it resets the connection because of "duplicate data path-id".
Here is the wireshark traces:

And the controller log:
