I am running Debian Bullseye on a Dell Precision 7730 laptop. It has a consumer-style e1000e NIC, specifically the I219-LM. I've run Ubuntu on this computer, too, and I noticed this problem I'm having on their platform, as well.
Basically, when I start up the computer, as soon as I log in, the NIC disconnects and re-connects over and over again, making it completely unusable. I generally have to turn off the phys NIC connection and rely on WIFI, which to me seems like an unacceptable solution.
I've tried turning off altnames and setting autoneg off, the autoneg off + full duplex appears to increase the intervals between disconnect/reconnections, but it continues happening. I generally compile my own kernels, but I have been using the stock Debian kernel lately in order to make my system more compatible with the release so hopefully if I file a bug report it can be more useful. I'm also trying to see what I can do on my end to lessen the problem, because I don't just want to file a bug report arbitrarily, but it's looking like it's likely to go in that direction.
Here's an illustration of the issue:
