imx6q-sabresd开发板scp拷贝大文件网络时断时续问题

各位大神,好。
imx6q-sabresd开发板网络通信。
电脑Linux虚拟机scp拷贝文件进入开发板。
经常提示如下日志:
fec 2188000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
fec 2188000.ethernet eth0: Link is Down
IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
fec 2188000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx

拷贝小文件还好,拷贝大文件(>2M)就经常会出现上述提示
但是文件拷贝仍可以正常进行。拷贝完成后,在开发板中可以正常使用。
查看内核网络源码集配置,暂未发现问题。
求教各位大神,这是哪里的问题呢。
对了,使用的内核版本为4.9.88

Hi 475143463@qq.com , 

We are able to transfer the file with size (>2M) using scp and not getting any error. Can you please verify that your ethernet cable is working properly or not?

We are using kernel version 4.9.88 and our board is iMX6Q-SABRE-SDB. Our Ethernet cable's speed is 100 Mbps. 

Regards,

Radhika Somaiya.

Hi Radhika Somaiya,

Thank you very much for your reply.

But now,I have no idea to resolve it.

Here is the configuration about network.

Please give me some suggestions!!!

In addition, I connect the development board to the computer through the router.
