Bug Description
I recently got a Thinkpad T14 Gen2 with a I219-V network adapter (8086:15fc). I get very slow connection speeds and even total loss of connectivity without seeing much in the logs (like dmesg etc.). ethtool reports CRC errors and paket loss. Besides Ubuntu 21.04/kernel 5.11 I tried to install Ubuntu 20.04 (kernel seems to old) and i tried the e1000e driver directly from upstream (3.8.7) with no success.
A strange behaviour I observed: if connectivity is lost (notebook is not reachable via ping from another host), if I do something like "ping 8.8.8.8" on the notebook itself, it becomes reachable from the other host again.
Downloads in general are very slow if they work at all.
WLAN (AX210) seems to work fine, wired network using a USB-network adapter works fine, too.

I also tried fedora 34 (kernel 5.11) on this notebook with the same behaviour, so this seems to be a general kernel/ driver- problem. The pre-installed windows on this notebook does not have any problems regarding network connectivity.
