在openSUSE-Leap-15.3-DVD-x86_64下安装USB无线网卡驱动rtl88x2bu

台式机电脑已经安装openSUSE-Leap-15.3-DVD-x86_64和KDE桌面，USB无线网卡为翼联EP-AC1610，已经得知驱动模块名称为rtl88x2bu，当前openSUSE-Leap-15.3是不可以上网的，将USB无线网卡插入主机后端

一、让台式机电脑使用手机流量上网
安卓手机用数据线连接主机背后的USB接口——手机选择仅充电——设置——网络和互联网——热点和网络共享——USB网络共享
此时openSUSE-Leap-15.3打开firefox浏览器是能够正常上网

三、安装驱动rtl88x2bu
屏幕左下角SUSE图标——应用——系统——konsole终端——切换到root用户——按顺序逐条复制粘贴命令并回车执行

重启台式机电脑——单击右下角的WIFI图标——单击手机热点右边的连接——输入密码——测试能否正常上网

五、后记：之前踩过的坑
到https://github.com/cilynx/rtl88x2bu下载驱动源代码rtl88x2bu-5.6.1_30362.20181109_COEX20180928-6a6a.zip，在openSUSE-Leap-15.2下编译是不会报错的，还是非常顺利正常使用，但在15.3下就会报错，在www.github.com和https://gitee.com/试过几个驱动源代码都是同样报错
/root/rtl88x2bu-5.6.1.6_35492.20191025_COEX20180928-6a6a/os_dep/linux/ioctl_cfg80211.c:9952:3: error: ‘struct cfg80211_ops’ has no member named ‘mgmt_frame_register’
