I think I have the same issue with my laptop and dock (Dell TB16).
Laptop is new and installed in Fedora 28. All firmware are up-to-date.
Ethernet works fine unless I want to transfert a large amount of data. Session (sftp, rsync or scp) cut abruptly after a few seconds. Nothing relevant appears in system logs.
If I offload the RC checksums (as suggested above) using : ethtool --offload enp11s0u1u2 rx off
Everything works fine.
