常见说明

Q1 设置eth接口的mac地址

nvidia@tegra-ubuntu:~$ sudo ifconfig eth0 hw ether 00:a0:c9:00:00:01

root@ubuntu:/home/nvidia# ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.44  netmask 255.255.255.0  broadcast 192.168.2.255
        inet6 fe80::da4d:b07a:e097:addd  prefixlen 64  scopeid 0x20<link>
        ether 00:a0:c9:00:00:01  txqueuelen 1000  (Ethernet)

Q2 设置eth接口的MTU值

nvidia@tegra-ubuntu:~$ sudo ip link set eth0 mtu 9000
nvidia@tegra-ubuntu:~$
nvidia@tegra-ubuntu:~$
nvidia@tegra-ubuntu:~$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.44  netmask 255.255.255.0  broadcast 192.168.2.255
