ESP8266 Web Server to storing ap config to EEPROM.

Original by chriscook8 from esp8266.com I just modified to use ESP8266WebServer library for easy to handle the http request.

This is sample code not yet complete.

Todo

• when Wifi connected need to close the softAP.

最近有个需求需要检测RJ45网卡的网线有没有接上，而最近正在了解Netlink相关资料，刚好也看下通过Netlink可以进行检测，故在此做下粗略笔记：

    1.首先要创建一个Netlink Socket，在用户层使用如下参数来调用socket()函数：

       fd = socket(AF_NETLINK, SOCK_RAW, NETLINK_ROUTE);

// Netlink 是内核与用户空间进程通信的一种机制，采用与 UDP socket 非常类似的编程风格。（
// 与 UDP 类似，Netlink 通信也有服务器端和客户端。例如，Linux 内核作为服务器端，已经运行在那里。我们则编写 Netlink 客户端，给内核发消息，并获得我们想要的信息。

#include <string.h>           //memset, strlen
