开发板板配备2个千兆网口
- ETH0 RGMII：end0，默认网卡。
- ETH1 RGMII：end1。
- 请使用网线将开发板对应网口、PC 机连接至同一个路由器。
网络连通测试
进入文件系统，执行如下命令获取 IP 以及查看网口配置信息。

device interrupt 67执行如下命令测试网口连接外网是否正常，以访问"www.baidu.com"为例。"-I"代表指定网口，不加"-I"则使用默认网卡。可按"Ctrl + C"终止 ping 命令。

服务端
在开发板上联网安装iperf3工具，执行如下命令：
root@linaro-alip:/# sudo apt update
root@linaro-alip:/# sudo apt install iperf3开发板做服务端，执行以下命令:
root@linaro-alip:/# iperf3 -s
-----------------------------------------------------------
Server listening on 5201 (test #1)
-----------------------------------------------------------客户端
windows的iperf3工具可以在测试工具包中获取。
在windows系统中打开powershell，进入iperf3工具所在路径下 windows做客户端发送数据，执行以下命令：
.\iperf3.exe -c 192.168.137.149 // 192.168.137.149为服务端IP地址测试结果
- 服务端
