目前支持wpa3的client毕竟还少，因此决定用树莓派作为wpa3 client，同时为了方便分析wpa3有关的supplicant和 kernel的代码流程，决定手动编译。

编译之前需要下载树莓派对应的工具链和driver patch。

https://community.cypress.com/docs/DOC-17441
git clone https://github.com/raspberrypi/tools ~/tools
git clone --depth=1 --branch rpi-4.14.y https://github.com/raspberrypi/linux

如果下载较慢可以直接通过网盘下载，我已经把对应的工具上传到了网盘

下来是步骤，按照这个步骤一定会成功

/*首先在ubuntu上编译树莓派的内核，我用的是ubuntu 18*/
sudo apt-get install git bison flex libssl-dev
/*下载工具链*/
git clone https://github.com/raspberrypi/tools ~/tools 或  unzip tools-master.zip  echo PATH=$PATH:~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin >> ~/.bashrc
source ~/.bashrc/*下载kernel*/
git clone --depth=1 --branch rpi-4.14.y https://github.com/raspberrypi/kernel  或 unzip linux-rpi-4.19.y.zip/*解压cypress*/
unzip cypress-fmac-v4.14.77-2019_1031.zipcd kernel
cp -r ../cypress/cypress-patch ./*给kernel打patch*/
for i in cypress-patch/*.patch; do patch -p1 < $i; done
按照默认选项一路回车就行
/*我粘贴了打完patch之后的最后一段*/
