I can confirm the patch works on the TB15 at my hand, can you guys try patched 4.11 kernel [1] on TB16?
I applied the patch to 4.11 - the patch cannot be cleanly applied to Xenial/Yakkety/Zesty kernel. I'll do the proper backport when the patch is being accepted by upstream maintainers.

RTL8153 Gigabit Ethernet Adapter which is on usb3 bus in my docking station (Dell TB16) which is attached to my laptop (Dell XPS9550) via Thunderbolt 3. I get usb related kernel error messages when I initiate a high speed transfer (by issuing wget http://cdimage.ubuntu.com/daily-live/current /zesty-desktop-amd64.iso) and the download fails. This does not happened when the Ethernet adapter is connected to a 100Mb/s switch, but only when connected to 1000Mb/s. It also does not happened with slow traffic (e.g. web page browsing). This is not a new bug with kernel 4.10, but has been going on since at least 4.7 and maybe (probably?) since forever. I'm aware of several others with this configuration (RTL8153 on usb3 behind thunderbolt 3) that have the same issue. This bug is also not specific to Ubuntu; I also get it on Arch Linux. I've also tested and seen this bug with several different models of thunderbolt 3 docks.

I've reported it to the realtek kernel dev team and they don't think their RTL8153 driver (in this case the r8152 module) is to blame, but instead that it's an xhci_hcd issue. If you look through the dmesg log attached here, you'll see that at 45.967025 I plugged the thunderbolt 3 cable from my dock into my laptop.
