软路由重装之后还要自己配置上网设置啥的
比较麻烦，所以自己编译一个属于自己的openwrt固件

优化内容

国内优化

更换opkg为国内清华源镜像
cp /etc/opkg/distfeeds.conf /etc/opkg/distfeeds.conf.bak sed -i 's#https\?://downloads.openwrt.org#https://mirrors.tuna.tsinghua.edu.cn/openwrt#g' /etc/opkg/distfeeds.conf

删除grub引导等待时间

sed -i 's/set timeout=5/set timeout=0/g' /boot/grub/grub.cfg

中文界面

luci-i18n-base-zh-cn

扩容需要的插件

block-mount
mount-utils
libmount1

网络优化

网口配置：br-lan 绑定 eth1+eth2+eth3，eth0 为 WAN 口
LAN 地址：10.0.0.1/24
WAN 协议：PPPoE 拨号
