I guess this dependency is an issue on non-linux systems, when you must
use those defines in a generic implementation. Can you confirm this is
the motivation here?
If so, I think it would be clearer to state "in order to avoid
dependency of DPDK on linux headers".

This file is delivered alongside the PCI lib, targeting userspace.
This seems to be an exception to the license policy described in
license/README. Code shared between kernel and userspace is expected
to be dual-licensed BSD-3 and GPL-2.0.
As it is a copy of Linux user includes, re-licensing it as BSD-3 as well
is not possible.
So I think it might require a techboard + governing board exception
approval. Ferruh or Thomas, what do you think?
