I do have a host with two RDMA HCAs connected to the target (Linux), for "normal dm-mpath" test I do nvme connect with the host traddr argument for both of the HCAs and get two nvme block devices which I can add to multipath. Using your patchset and doing the sanme double connect trick I get the same two block devices of cause. How do I connect using both paths?
