I too was having the issue with Ethernet on Linux Mint 18.1 at 4.4.0-100.
I have the USB3 Ethernet adapter:

with USB3 adapter:
https://www.amazon.com/gp/product/B01GGKYXVE
If I plug this into the thunderbolt port on the TB16 and then use the USB3 Ethernet adapter, my Ethernet hasn't dropped out in the past few days. I've tested with copying large files.
Let me know if I can provide further details.
