/* When a switch initially connects to a controller, the controller may spend a
* little time examining the switch, looking at, for example, its datapath ID,
* before it decides whether it is willing to control that switch. At that
* point, it either disconnects or starts controlling the switch.
*
* This function returns a guess to its caller about whether 'b' is OpenFlow
* message that indicates that the controller has decided to control the
* switch. It returns false if the message is one that a controller typically
* uses to determine whether a switch is admissible, true if the message is one
* that would typically be used only after the controller has admitted the
* switch. */
