summary
本文介绍了如何利用 GitHub Action 自定义构建红米 AC2100 路由器的 Padavan 固件。首先，在 GitHub 上新建一个仓库，并下载 Padavan 固件的源代码。然后，根据自己的需求修改配置文件和自定义脚本。接着，在 GitHub Action 的配置文件中设置编译环境和编译参数，并将编译生成的固件上传到 GitHub Release。最后，使用自定义脚本对固件进行进一步的配置和修改。通过这种方法，可以快速自定义构建适合自己需求的 Padavan 固件。
手头上使用的红米 AC2100 路由在到手刷为 OpenWRT 后一直稳定运行几年时间。前些日子将 OpenWRT 相关的功能需求转移到软路由上后，便想着将其再刷一下，只承担最基本的路由功能。于是选择了 Padavan 固件。
Padavan固件是一个基于华硕路由器的第三方固件，它提供了许多额外的功能和定制选项，使得用户可以更好地控制他们的路由器。Padavan固件基于开源项目，因此用户可以自由地定制和修改它以满足自己的需求。
关于Padavan固件的更多信息和下载链接可以在以下网站找到：
https://bitbucket.org/padavan/rt-n56u/src/master/
网上有较多现成的固件，可以直接下载刷入，但基本都经过了各种修改，综合考虑后决定利用 GitHub Action 来自行编译构建固件。
如下为内核基于 4.4 版本的 Padavan 源代码

新建一个仓库，参照上面源码中的编译说明，编写自定义配置及 GitHub Action 配置文件即可快速自定义构建固件。

设备编译配置

可参考 Padavan 源码中对应的文件进行修改，这里我只添加了 Adbyby plus 和 WireGuard 两个额外插件，其余均未引入。
