I have CentOS 8 Stream.

I would first try to determine if it's a hardware or software issue. Are you able to try replacing the device? Or are you able to try reverting to an earlier kernel to see if you can determine when the issue started to manifest, if it is a software issue.

I'm using the e1000e driver on some of my RHEL7 systems and have no issues with the hardware/driver combo under quite heavy usage.
