编译华硕路由器ACRH17源代码小记

源码包中有说明：

The GPL source is created for ASUS wireless router related products. Please visit the ASUS support site (http://support.asus.com) to get the latest GPL tarball.It has a lot in common with many wireless router open source projects, including Oleg/Tomato/DD-WRT/OpenWRT. Thanks the developers of those projects for making the source code available.

先是用我装的centos7_x64编译，结果报Lib_tool未安装一类的错误，查看安装的软件包已经安过了x64版本的，然后搜索仓库没有x86版本的，猜没是这个原因。

然后就又在vbox上装了ubuntu的x86版本，再编译一切基本顺利。

我主要是想编译ebtables软件和内核模块，来开启真正的访客网络无线隔离。

编译完成后到linux源码目录，make menuconfig发现ebtable相关的都编译成了模块（M）。

又下载了一个此型号路由器的升级固件，用7zip打开，所有目录看了两遍，发现在\lib\modules\3.14.77\kernel\net\bridge\netfilter\目录已经有相关ko文件，

只是\lib\modules\modules.dep没有全部加载，尤其是ebt_ip.ko这个支持ipv4的没有加载，等有时间了把这些模块全部加载了，试下我以前的防火墙规则隔离无线是否正常。
