解决方法: 驱动问题, 需要关闭网卡的一些属性.
1 ethtool -K eno1 gso off gro off tso off tx off rx off rxvlan off txvlan off sg off
使用apt install -y ethtool以安装以太网工具.
此改动仅限本次开机期间, 重启后会失效. 持久化保存需要修改 /etc/network/interfaces
在对应的网卡配置下, 与address同级添加配置:
1 2 3 4 5 6 7 8 9 10 offload-gso off offload-gro off offload-tso off offload-rx off offload-tx off offload-rxvlan off offload-txvlan off offload-sg off offload-ufo off offload-lro off
不修改interfaces也可以使用另一种方式, 即开机运行一次ethtool命令, 创建一个ethfix.service
1 2 3 4 5 6 7 8 9 [Unit] Description=Fix network card on boot [Service] Type=simple ExecStart=/usr/sbin/ethtool -K eno1 gso off gro off tso off tx off rx off rxvlan off txvlan off sg off [Install] WantedBy=multi-user.target
运行systemctl enable ethfix, 即可在今后开机时自动应用改动.
