芯驰D9开发板上有路以太网接口，测试下两个以太网接口通信。1、开发板接口

2、将两个**接口都连接到交换机，通过命令配置**连接
root@myd-jd9x:~# ifconfig eth0 192.168.1.100 netmask 255.255.255.0 up

root@myd-jd9x:~# ifconfig eth1 192.168.1.101 netmask 255.255.255.0 up

3、查看**的IP地址

4、使用ubuntu虚拟机ping两个**

**连接正常
5、两个**同时登录SSH

6、测试程序
udp_server.c

7、编译
ubuntu:/opt/myd-jd9# aarch64-linux-gnu-gcc -o udp_server udp_server.c

ubuntu:/opt/myd-jd9# aarch64-linux-gnu-gcc -o udp_client udp_client.c

ip:192.168.1.100 运行udp_server
ip:192.168.1.101 运行udp_client

8、两路网口收发测试
