"OpenIB BSD" is not a defined SPDX identifier. There is an SPDX
identifier "Linux-OpenIB"
https://spdx.org/licenses/Linux-OpenIB.html
but I believe that is not a match to what's in these files
(specifically, the wording of the disclaimer), rather I believe what
you want here is BSD-2-Clause, but you may want to check that.
