When application supports FI_RX_CQ_DATA, efa-direct can onboard this mode by disabling unsolicited write recv feature in QP. As in this case customer can post recv buffer for rma cq data operations. If this mode is not requested, efa-direct should return a 0 cq data size when unsolicited write recv as the rdma write with imm will not work it requires application to post recv buffer.

Have a long argument to not set FI_RX_CQ_DATA in hints, and keep the default behavior unchanged as requesting FI_RX_CQ_DATA Signed-off-by: Shi Jin <[email protected]> (cherry picked from commit 0b2034b)
Only for writedata rma op, only for efa-direct Only applied on selected test items to save test durations Signed-off-by: Shi Jin <[email protected]> (cherry picked from commit 7a7ad03)
Newly added rx cq data tests increase the test duration Signed-off-by: Shi Jin <[email protected]> (cherry picked from commit e1d2ffc)
…d write recv When unsolicited write recv is not supported, RDMA write with immediate data operations consume an RX buffer, requiring the FI_RX_CQ_DATA mode bit to be set for FI_RMA. cq_data_size shouldn't be used to indicate support for fi_writedata because there are reasonable use cases where the cq_data_size is 0 and the completion needs to be generated.
