I pull *some* OFED code. I don't pull it all. There are things in OFED
I won't accept until they've gone upstream. Hence, RDS is not in our
offering. We made the mistake of taking SDP long ago and we'll carry
that forward, but we generally look for things to be upstream before
pulling them from OFED at this point (or at least have been submitted
upstream and is being worked towards acceptance).
In terms of user space, given a choice between a released tarball or the
custom OFED tarball, I choose the released tarball. So, I currently
have Roland's libibverbs, libmthca, and libmlx4.
