"some other parameters" mean parameters (modules, classes, static
definitions or else)
to send messages to switches, right?
----
No, the opposite. When switch connects to the controller, the controller
gets the event message with some information, including datapath ID.
Let's say switch will say not only his datapath id but also its model name.
So the question is how can I modify the event message structure.
Thanks.
