The issue is not unique to the integrated NIC in the dock (so the
current workaround in r8152 is not sufficient). I have a r8152-based TP-
LINK UE300 USB3-to-GigE dongle connected to my TB16 dock and I'm getting
the same packet corruption when I don't turn off rx checksum offloading.

The dongle is plugged into the internal USB hub in my Dell U2715H
screen, which is in turn plugged into the TB16 (latest firmware 1.0.0),
connected to my XPS 15 9560 (latest BIOS 1.11.0, Linux
4.18.7-200.fc28.x86_64 at the moment).
I've also seen someone mentioning that (some) USB3 ports on the TB16 are
in fact Alpine Ridge pass-through. That does not seem to be the case
here, all three ports on my TB16 go through the ASMedia host controller:
0e:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host
Controller
The r8152 workaround triggers just fine for the integrated NIC in the
dock:
usb 4-1.2: reset SuperSpeed Gen 1 USB device number 4 using xhci_hcd
usb 4-1.2: Dell TB16 Dock, disable RX aggregation
