Title:
Massive network problems with I219-V on Thinkpad T14 Gen2 (e1000e)

Status in OEM Priority Project:
Confirmed
Status in linux package in Ubuntu:
Confirmed

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.
