      移植WiFi驱动RTL8188FU，是使用USBWiFi芯片，但是上诉的几个函数一直找不到定义，搜索了全部的代码，都没有发现这些函数的定义，求大佬指点
      sw_usb_enable_hcd
      sw_usb_disable_hcd
      script_parser_fetch

            @whycanservice 您好。我用的是全志的r528linux内核是5.4.61. RTL8723du。 我的报错信息是这样的。!1679636638005.png 我查看Makefile 发现它确实会编译这个函数。1679637460141.png 这个/platform/platform_ARM_SUNxI_usb.c确实用到了这个三个函数。 但是我在内核中搜索并没有找到有sw_usb_disable_hcd 和sw_usb_enable_hcd两个函数。script_parser_fetch 是在Uboot下的sys_config.h中有定义。
            1679637606209.png

            此外编译时发现驱动中/platform/platform_ARM_SUNxI_usb.c的#include <mach/sys_config.h> 头文件也无法找到。
            我就将它更改为了 #include </home/kerson/tina-r528/lichee/brandy-2.0/u-boot-2018/include/sys_config.h>
            我不知道sw_usb_enable_hcd(usb_wifi_host);sw_usb_disable_hcd(item.val);的具体作用，是否可以直接注掉。或者不用/platform/platform_ARM_SUNxI_usb.c 这个文件？

              @hy123456 我这也搜索不到定义，但是貌似没有使用那一段代码，直接编译通过的

                        @fanfan RTL8188FU只有150mbps，正常来说跑到120mbps左右即达标，如果需要跑到200m可以考虑更换aw869a wifi
