That patch note makes it sound like there will be a hardware/firmware fix that will hopefully resolve this. If so it is very unlikely that upstream will accept your patch, as the proper fix will really be to upgrade your firmware. A more preferable patch will be to log a big bad warning if you have TB16 with the bad firmware revision. The kernel people don't tend to like to BUG hardware issues that are resolvable through firmware updates.

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.
