openwrt 国内中科大镜像源 配置

科大的国内源，虽然更新不及时，不过胜在速度快，我已经用了近快六年时间了。昨天升级路由器，搞丢了配置，重新配置好，记录于博客，用以备忘。我的路由器是极路由1S，HC5661。如果是其他型号的路由器，需要对配置进行修改，把ramips/mt7620替换为路由器的代号。

上一个稳定版的openwrt 固件使用ustc镜像的配置如下：

src/gz openwrt_core https://mirrors.ustc.edu.cn/lede/releases/18.06.5/targets/ramips/mt7620/packages
src/gz openwrt_kmods https://mirrors.ustc.edu.cn/lede/releases/18.06.5/targets/ramips/mt7620/kmods/4.14.151-1-eb0249176c60bd37f771ab7e564db34d

2020年5月10号更新，最新版本的openwrt 使用ustc的镜像配置如下：
