processing the sent data, clear tbusy in the sending end interrupt, and use mark_bh () to call the notification system to continue sending. Another method is to disable tbusy from being set to 1, so that the system always considers the hardware idle, but reports cannot be sent successfully. The system will always try again. 3.3 Flow Control) Traffic control is required for sending and receiving network data. These controls are implemented in the sys
