I also just went through the process of reproducing this while watching the kern.log. Absolutely 0 messages came out. If you find some verbose debugging you want me to turn on let me know.

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.
