lenovo network drivers

Notifies the driver when a frame is receivedin a network environment, when a device (network card) receives a data frame, it needs to notify the driver to process it. There are several notification mechanisms:Polling :The kernel keeps checking to see if the device has something to say. (More resource-intensive, but in some cases the best method)Interruption:when a particular event occurs, the device driver

processes and kernel threads while not sleeping; If the deferred task does not have any requirements for the delay time, the work queue is used, which is usually a trivial task. In fact, the essence of a Task Force column is to hand work to kernel threads, so it can be replaced with kernel threads. But the creation and destruction of kernel threads is a high requirement for programmers, and the work queue implements kernel thread encapsulation and is not easy to make mistakes, so we al
