I seem to be seeing this again with the following kernel: Linux xps15 5.0.0-17-generic #18-Ubuntu SMP Tue Jun 4 15:34:08 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
The problem is not so much checksum errors, but mostly that transfers are abruptly aborted.

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.
