The initialization program completes hardware initialization, variable initialization in device, and system resource application. SendThe program is automatically called when data is sent at the upper-layer protocol layer of the driver. Generally, the error message is not sent to the driver.Instead, the hardware sending function is used to send data di

1. Linux system device driver overview
1.1 Linux
Linux network protocol stack kernel initialization can be divided into device link layer (e100_module_init, net_dev_init), network layer (inet_init), transmission layer (proto_init), and application layer (sock_init) initialization. Because the physical layer is a specific network
