Before going down the rabbit hole, I would:
1. update firmware for the computer and card
2. use a new [known good] ethernet cable
3. change ports at the switch
It is possible the messages are somewhat expected since they appear to
be part of PCI AER (Advanced Error Reporting). It is possible another
host is putting bad bits on the wire, and your machine is correcting
them. If another machine on your network is responsible, then you
might see different results if you plug your computer directly into
your router rather than a switch on your internal network.
There is another discussion of PCI AER at
<https://forums.developer.nvidia.com/t/pcie-bus-error-severity-corrected-type-physical-layer-id-0010-receiver-id/251840/19>.
You might find something of interest in it.
