openwrt 修改feeds.conf.default为GitHub源

lede和openwrt合并之后
lede官网挂了。。
git.openwrt.org，也访问不了。。

只要去github上找最新源码：

git clone https://github.com/openwrt/openwrt.git

最新的lede

git clone -b lede-17.01 https://github.com/openwrt/openwrt.git

但是问题又来了，，
./script/feeds update -a 又挂了，，

查看文件feeds.conf.default ：

src-git packages https://git.openwrt.org/feed/packages.git
src-git luci https://git.openwrt.org/project/luci.git
src-git routing https://git.openwrt.org/feed/routing.git
src-git telephony https://git.openwrt.org/feed/telephony.git
#src-git video https://github.com/openwrt/video.git
#src-git targets https://github.com/openwrt/targets.git
#src-git management https://github.com/openwrt-management/packages.git
#src-git oldpackages http://git.openwrt.org/packages.git
#src-link custom /usr/src/openwrt/custom-feed

git.openwrt.org访问不了，无法更新，只能使用github源地址：
更新如下：

src-git packages https://github.com/openwrt/packages.git
src-git luci https://github.com/openwrt/luci.git
src-git routing https://github.com/openwrt-routing/packages.git
src-git telephony https://github.com/openwrt/telephony.git
src-git management https://github.com/openwrt-management/packages.git

OK，./script/feeds update -a 可以了
