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 board is taken
offline. If v is non-zero, the device or interface board is left operational, or online.
If a device or an interface board is taken offline, the board or device descriptor (ud) is no
longer valid. You must execute an ibfind or ibdev to access the board or device
again.
