Description
ibonl resets the board or device and places all its software configuration parameters in their pre-configured state. In addition, if v is zero, the device or interface is placed offline. If v is non-zero, the device or interface is left operational, or online.
If a device or an interface is taken offline, the board or device descriptor (ud) is no longer valid. You must execute an ibdev or ibfind to access the board or device again.
