Rock 3a ping router has 75% packet loss, but the delay is normal. Route ping Rock 3a also has very serious packet loss and can hardly be used。
I tried replacing the router and the switch problem still reappears，I tried the ubuntu and debian system packages, and the same problem when the version was released at different times。I tried changing the flow control on the router and restarting the interface, the problem still occurs.
dmesg gives a lot of errors
