platforms, I haven't looked at the intermediate process yet. The concern is how wpa_supplicant sends the command to the DRIVER after receiving the upper-layer command, the parsing action of the DRIVER after receiving the command, the process of calling the DRIVER function, and the details of the DRIVER's register control. Because the code should be kept confiden
