To be compliant with the DPDK licensing guidelines, switch to
BSD-3-Clause. It can be done safely since the BSD headers from which
these files derive also exist as a BSD-3-Clause license in FreeBSD.

Not sure how much it matters but in the document Hemant put, order is different,
it starts with Copyright line instead of SPDX line:

"
Copyright (C) [YEAR] NAME-OF-COPYRIGHT-HOLDER
SPDX-License-Identifier:        BSD-3-Clause
"

So I assume for multiple Copyright holder:

"
Copyright (C) [YEAR] NAME-OF-COPYRIGHT-HOLDER
Copyright (C) [YEAR] NAME-OF-COPYRIGHT-HOLDER-2
Copyright (C) [YEAR] NAME-OF-COPYRIGHT-HOLDER-3
SPDX-License-Identifier:        BSD-3-Clause
"

And do we still need "All rights reserved." ?


I am for following same syntax in all files (whichever is chosen), this may
helps us in the future for scripting licensing checks.

<...>

License text example in [1] starts from Copyright and has All rights reserved.
I agree that template should be clearly specified from the very beginning.
