That will come next (I plan to add that so ULPs can get lower latency).

But it seems kernel support is needed even for libibverbs since its the
kernel that calculates wqe stride to put in cmd interface. No?

And also max sge for memfree.
May be a good idea, but seems to apply even without inline data.
If you add this I'd prefer that you apply this patch first to avoid
merging conflicts.
