Title:
TB16 dock ethernet corrupts data with hw checksum silently failing

Bug description:
It looks like TCP rx and tx checksum offloading is broken on the TB16 dock's ethernet adapter. For example downloading a large file such as the Ubuntu ISO, and then running an md5sum on it yields the incorrect md5sum. This is because
rx-checksumming: on
tx-checksumming: on
and both set to on by default.

Running sudo ethtool -K <TB16 eth device> tx off rx off, allows the
download to complete correctly. This is very bad since this can cause
very bad untrustworthy behavior.

This was conducted using an Dell Precision 5520 on Ubuntu 16.04+linux-
generic-hwe-16.04-edge.

Thank you
