Yes, This file can be added with /* SPDX-License-Identifier: BSD-2-Clause-FreeBSD */. We can also make the xgbe_osdep.c and xgbe_osdep.h tagged with the same SPDX License Identifier.

Once we get the clarity about the SPDX Licence Identifier for other files (using BSD-3-Clause with additional text), we shall make all the changes and submit another version for review.

To understand about "All rights reserved", this text is only related to the copyright and unrelated to the License right? And "year" means the year the particular file came into existence for the first time in general and if multiple years specified, it means the years that file is actively touched, right?

If my understanding is right, does changing the year to 2020 is the problem here?

Correct, the text "All rights Reserved" is associated with the copyright and not the License. But this text, "All rights reserved" is no longer needed, and we are trying to remove it when we can and not use it on any new code if possible. All the templates in FreeBSD have been updated to note have this text.

Your statement about the "year" is the interpretation I have always used, some disagree on that and say it is valid to just list the first and last years as a range 2014-2020 for example.

There is no problem with the year use of 2020 in this file, it is a new file.
