In part - I don't see that IRD or ORD are set through the modify QP calls in the
rdma_cm.  I'm guessing that the values are passed to the driver, and are used by
the driver when transitioning to RTS?

Basically, I'm trying to determine if the fix to the librdmacm affects iWarp at
all (I don't believe that it does), and if a similar fix would also work in the
kernel.  I'm pretty sure that it will for IB, but I'm not sure what the behavior
would be for iWarp.
