Pi4 kernel 5.10.17-v8+ eth0: hw csum failure

Start by reproducing the eth0: hw csum failure messages on a Pi 4 using kernel 5.10.17-v8+, while receiving packets over the built-in ethernet port, and inspect the reported dmesg output. No source file or test is named; done means identifying and correcting the kernel networking cause so the errors no longer flood dmesg and syslog.

Is this the right place for my bug report?
I believe so.

Describe the bug
dmesg and the syslog are flooded with errors stating eth0: hw csum failure.

To reproduce
List the steps required to reproduce the issue.

1. Receive packets over the built-in ethernet port

Expected behaviour
The error doesn't occur.

Actual behaviour
The error occurs.
