When importing the patch5752075144(IB/SA: Add OPA path record type), a new header file should have been added to the repo as part of the patch. However, as the patch didn't apply cleanly using git am, I instead used patch manually, and followed that up with git add -u, which misses new files. This adds the new file back in. Fixes:5752075144(IB/SA: Add OPA path record type) Signed-off-by: Doug Ledford <dledford@redhat.com>
