TinkerBoard2主板自带的无线模块为RTL8822CE，PCIe接口
之前在风火轮下载的Linux源码编译出来的BuildRoot根文件系统没有相关的驱动文件

[root@rk3399:/]#1、配置无线网卡驱动
在kernel路径下执行make menuconfig，然后按/输入8822，Ok
LuaSymbol: RTL8822CE [=m] │ │ Type : tristate │ │ Prompt: Realtek 8822C PCIE WiFi │ │ Location: │ │ -> Device Drivers │ │ -> Network device support (NETDEVICES [=y]) │ │ -> Wireless LAN (WLAN [=y]) │ │ -> Rockchip Wireless LAN support (WL_ROCKCHIP [=y]) │ │ (3) -> Realtek Wireless Device Driver Support (RTL_WIRELESS_SOLUTION [=y]) │ │ Defined at drivers/net/wireless/rockchip_wlan/rtl8822ce/Kconfig:1 │ │ Depends on: NETDEVICES [=y] && WLAN [=y] && WL_ROCKCHIP [=y] && RTL_WIRELESS_SOLUTION [=y] && PCI [=y]确认配置没问题，RTL8822CE编译成模块，其他配置都有打开
在8822ce源码目录也确实编译了8822ce.ko驱动文件，但是打包的时候没有拷贝
在Linux_SDK源码目录下执行make menuconfig，没有8822CE选择，而且wifi chip默认选择AWCM256，导致BR2_PACKAGE_RKWIFIBT_VENDOR的值为CYPRESS

添加以下四个package
iw: 可用于OPEN、WEP这两种"认证/加密"，以及扫描WIFI热点等；
wpa_supplicant: 可用于前面4种"认证/加密"；
hostapd: 能够使得无线网卡切换为AP模式；
dhcp: STA模式使WIFI网卡动态获取IP，AP模式分配IP；

3、使用dhclient配置
执行wifi_start.sh连接网络后可以使用dhclient自动配置IP地址和DNS
Lua

4、编译时自动拷贝8822ce.ko
修改./buildroot/package/rockchip/rkwifibt/rkwifibt.mk，编译buildroot时就可以拷贝8822ce.ko到buildroot/output/rockchip_rk3399_tinkerboard2/target/system/lib/modules/8822ce.ko，我是执行rm -rf ./buildroot/output/后再编译buildroot的

或者执行make clean
