第一部分是kernel
内核配置参考rk文档，把device driver 下wireless相关的先勾选上。
编译到buildin有问题，识别不到，所以打算编译成ko
cd kernel/drivers/net/wireless/rockchip_wlan/rtl8188eu
make -C /home/lzm/workspace/rk3288/zy_n10/kernel/ M=`pwd` modules
得到8188eu.ko
lsusb，看vid pid，是存在的
看初始化函数，发现被注释，修改打开
第二部分，android打开Settings配置

cd hardware/libhardware_legacy
mm
android源码目录下的build/envsetup.sh文件，描述编译的命令
- m: Makes from the top of the tree.
- mm: Builds all of the modules in the current directory.
- mmm: Builds all of the modules in the supplied directories.
要想使用这些命令，首先需要在android源码根目录执行. build/envsetup.sh 脚本设置环境
m：编译所有的模块
mm：编译当前目录下的模块，当前目录下要有Android.mk文件
mmm：编译指定路径下的模块，指定路径下要有Android.mk文件
下面举个例子说明，假设我要编译android下的\hardware\libhardware_legacy\power模块，当前目录为源码根目录，方法如下：
1、. build/envsetup.sh
2、mmm hardware/libhardware_legacy/power/
或者 ：
1、. build/envsetup.sh
2、cd hardware/libhardware_legacy/power/
3、mm
