Although as Boris pointed out, perhaps the hack in OMPI is no longer
needed at all...

Status: I have a patch from Arlin
FWIW, I would marginally prefer if this bug is tracked in the Open
MPI trac ticket system, not the OFA bugzilla (Steve W. will have
write access there as soon as Chelsio submits their OMPI 3rd party
contribution agreement). We've traditionally [mostly] tracked OMPI
bugs in the OMPI bug
I agree OMPI trac ticket #890 should cover this. I will test the
suggested fix, just removing that one line from btl_udapl.c, on Solaris.
I am still not set up on Linux so hopefully Steve can confirm there.

ofed-1.2 supports iwarp and the chelsio rnic. It can be accessed
directly via the ofa verbs and ofa rdma-cm _as well as_ via udapl.
I'm attempting to run OMPI
So then I agree with Andrew, I think you are trying to impose
restrictions on uDAPL which are not part of the Spec.

The reason it is hard or impossible to solve this in the DAPL layer is
that any rdma operation on the QP affects the state of that QP and the
associate CQs. In addition, if you use an RDMA send to enforce this you
impact the other side by consuming a RECV buffer. So its hard if not
impossible to
