From 87f0faadc68534668802a85ae670435bc90830b3 Mon Sep 17 00:00:00 2001 From: Doug Ledford Date: Mon, 1 May 2017 16:35:59 -0400 Subject: IB/SA: Add OPA addr header When importing the patch 57520751445b (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.
