Subject: [PATCH] b=21426 i=wangyb i=yangsheng

Allow the easy dropping in of patches to OFED.  This is mainly meant as a
mechanism to test patches from OFA prior to them committing them to their
upstream.

We should likely never actually release a version of Lustre and OFED built
with any OFED patches.
