I'm not aware of this and this is the first time I heard for the checksum offloading issue of nfe(4). Include dmesg output for your controller and let me know whether it's really regression from 7.2-RELEASE. If you have reliable way to reproduce the issue, please also let me know. There is no nfe(4) source code differences between 7.2-RELEASE and 8.0-RELEASE.
