While doing some tests, I've found that rdma_client failed
on my QLogic/Intel QLE7340 / QLE7342 HCA:
# rdma_client
rdma_client: start
rdma_post_send 22
rdma_client: end -1
I had a deeper look on the examples and found that max_inline_data was
returned as 0,The man page to ibv_create_qp() states: The function ibv_create_qp() will update the qp_init_attr->cap struct with the actual QP values of the QP that was created; the values will be greater than or equal to the values requested.
From this, it sounds like there is a bug in the Intel provider. The ibv_create_qp call should have failed.
