Device Driver Open

Edit online

The open entry point for the device drivers perform a synchronous open of the specified network device.

The device driver issues commands to start the initialization of the device. The state of the device now is OPEN_PENDING. The device driver invokes the open process for the device. The open process involves a sequence of events that are necessary to initialize and configure the device. The device driver does the sequence of events in an orderly fashion to make sure that one step is finished executing on the adapter before the next step is continued. Any error during these sequence of events makes the open fail. The device driver requires about 2 seconds to open the device. When the whole sequence of events is done, the device driver verifies the open status and then returns to the caller of the open with a return code to indicate open success or open failure.

After the device has been successfully configured and connected to the network, the device driver sets the device state to OPENED, the NDD_RUNNING flag in the NDD flags field is turned on. In the case of unsuccessful open, both the NDD_UP and NDD_RUNNING flags in the NDD flags field are off and a non-zero error code is returned to the caller.
