D1 LicheeRV Dock 移植RTL8723DS驱动

RTL8723DS焊接上去了，现在把驱动程序移植上去。

咱先获取源码：https://github.com/lwfinger/rtl8723ds

下载完成后，把驱动文件复制到 tina-d1-open\lichee\linux-5.4\drivers\net\wireless\rtl8723ds 里，没有rtl8723ds文件夹记得新建一个。

修改tina-d1-open\lichee\linux-5.4\drivers\net\wireless\Makefile，加一行 obj-$(CONFIG_RTL8723DS) += rtl8723ds/

修改tina-d1-open\lichee\linux-5.4\drivers\net\wireless\Kconfig，加一行 source "drivers/net/wireless/rtl8723ds/Kconfig"

修改tina-d1-open\lichee\linux-5.4\drivers\net\wireless\rtl8723ds\os_dep\linux\os_intfs.c
加一行MODULE_IMPORT_NS(VFS_internal_I_am_really_a_filesystem_and_am_NOT_a_driver);

修改tina-d1-open\lichee\linux-5.4\drivers\net\wireless\rtl8723ds\os_dep\linux\rtw_cfgvendor.c
在每一行.policy = VENDOR_CMD_RAW_DATA, 下面加上 .maxattr = 1,

修改tina-d1-open\target\allwinner\d1-lichee_rv_dock\modules.mk，增加以下内容：

define KernelPackage/net-rtl8723ds
  SUBMENU:=$(WIRELESS_MENU)
  TITLE:=RTL8723DS support (staging)
  DEPENDS:= +r8723ds-firmware +@IPV6 +@USES_REALTEK
  FILES:=$(LINUX_DIR)/drivers/net/wireless/rtl8723ds/8723ds.ko
  AUTOLOAD:=$(call AutoProbe,8723ds)
endef

define KernelPackage/net-rtl8723ds/description
  Kernel modules for RealTek RTL8723DS support
endef

$(eval $(call KernelPackage,net-rtl8723ds))

（其中的d1-lichee_rv_dock 是我的板级配置，请选择自己的板级配置比如d1-nezha，如下图）

进入内核配置，勾选Realtek 8723D SDIO or SPI WiFi为Module（<M>不是<*>）

make kernel_menuconfig

Device Drivers ->
     Network device support ->
           Wireless LAN ->
                  <M>   Realtek 8723D SDIO or SPI WiFi

进入Tina配置，勾选相关驱动

make menuconfig

Firmware  ->
     <*> r8723ds-firmware.............................. RealTek RTL8723DS firmware

Kernel modules ->
     Wireless Drivers  ->
        <*> kmod-net-rtl8723ds........................... RTL8723DS support (staging)

保存，编译，打包

make -j65535
pack

烧录后就能看到了
