Looks like the following commit exposed a bug in the chelsio driver.
iw_cxgb3 was _not_ setting the max_qp_init_rd_atom attribute.

librdmacm/cma: provide sanity checks for max outstanding rdma ops
Ensure that the responder_resources and initiator_depth values
provided by the user are supported by the local hardware. This
traps errors sooner during connection establishment (when calling
rdma_connect), rather than waiting until the modify QP fails
(after calling rdma_accept).

I've opened bug 777 to fix this. Tziporet/Vlad, can we get this in
beta? I will provide a patch shortly.

Sean,
I'm testing iwarp usermode on ofed-1.3 and I always get a -22 error from
rdma_connect(). I tried rping and a home brew unit test program and bot
this this error. I'm diving in now to see who's returning it, but
wanted to give you a heads up...
Stay tuned...
Steve.
