Based on discussion with Kate Stewart this license is not a BSD-2-Clause, but is now formally identified as Linux-OpenIB by SPDX. The key difference between the licenses is in the 'warranty' paragraph. if_infiniband.h refers to the 'OpenIB.org' license, but does not include the text, instead it links to an obsolete web site that contains a license that matches the BSD-2-Clause SPX. There is no 'three clause' version of the OpenIB.org license. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Doug Ledford <dledford@redhat.com>
