I know Krishna Kumar is working on a solution for exchanging this info in private data so the IWCM can "do the right thing". Stay tuned for a patch series to review for this. But this functionality is definitely post OFED-1.2. So for the OFED-1.2, I will set these to the device max in the IWCM. Assuming the other side is OFED 1.2 DAPL, then it will work fine.
