/**
* @brief The QQtEthenetManager class
* 原理：
* S1:系统启动，调用init_net.sh
* S2:系统运行，用户通过页面设置WiFi或者有线的IP等，或者设置为自动获取。
* 保存IP到配置文件，启动时显示到用户页面上
* 保存IP等到init_net.sh，系统启动时，网络连接状态正常。
* 保存WiFi设置等到/etc/wpa_supplicant.conf
* S3:用户插拔网线，WiFi自动切换为有线。
* S4:用户重启系统，进入S1.
*
* 使用说明：
* 调用QQtEthnetManager::Instance(parent)，并且连接相应的WiFi信号和用户的槽
* 通过wifiList()，显示给用户看WiFi列表。每5s自动更新一次。在槽当中调用并更新界面
* 通过setCurrentWiFi()更换用户连接的WiFi。用户点击更改输入密码了，就调这个保存。会自动配置WiFi和根据用户IP或者DHCP重来连接新WiFi。
