当前 git HEAD 是一个高度实验性版本，请查找 commit 以获得可用版本
我相信当前版本已经足够可用，但是仍然有很多改进等待完成
暂时来说，懒得写 README，请先参照 博客文章 完成操作
如果遇到了任何问题，欢迎提出 Issues，但是更欢迎直接提交 Pull Request
由于新加入的 CONNMARK 影响，编译内核时需要添加
NETFILTER_NETLINK_GLUE_CTflag，否则会出现mnl_cb_run:Not supported错误
由于新加入的 ipset 影响，需要确保你的内核支持
hash:ip,port的 ipset 类型
# Enable the daemon
uci set ua2f.enabled.enabled=1
# At your option set fw rules
uci set ua2f.firewall.handle_fw=1
uci set ua2f.firewall.handle_tls=1

uci set ua2f.firewall.handle_intranet=1
# Apply your modifications

service ua2f enable
# Start the daemon
service ua2f start请确保添加此语句至开机自启

- pthread 支持，由不同线程完成入队出队
- 修复偶现的非法内存访问，定位错误是一个麻烦的问题 (疑似修复，继续观察)
- 配合 CONNMARK 与 ipset，不再修改已被判定为非 http 的 tcp 连接，期望减少 80% 以上的负载 (高度实验性实现)
- 清除 TCP Header 中的 timestamp，有论文认为这可以被用来识别 NAT 后的多设备，劫持 NTP 服务器并不一定有效
http 头包占比观察
