Device Driver Close

Edit online

The close entry point for the device drivers is called to close the specified network device. This function resets the device to a known state and frees system resources associated with the device.

The device will not be detached from the network until the device's transmit queue drains. That is, the close entry point will not return until all packets have been transmitted or timed out. If the device is inoperable at the time of the close, the device's transmit queue does not have to drain.

At the beginning of the close entry point, the device state is set to be CLOSE_PENDING. The NDD_RUNNING flag in the ndd_flags is turned off. After the outstanding transmit queue is all done, the device driver starts a sequence of operations to deactivate the adapter and to free up resources. Before the close entry point returns to the caller, the device state is set to CLOSED.
