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

In many cases, the same WiFi card supports multiple interfaces at the same time, for example, the 8686 WiFi card of Marvell supports both the SPI interface and sdio interface.
