I know there is some configuration that has to be done when using RDMA

find some help here https://community.mellanox.com/docs/DOC-2855
the section Non-mellanox
There are a couple of things we can try:
1. Remove the switch to simplify the equation - are the two machines
collocated such that you can just plug the NICs into each other and retry
If I keep everything the same (two servers and the switch) but swap perf
for the Linux nvme-rdma in-box driver + fio, the server is able to connect
and send IO's to the nvmf_tgt instance. My assumption has been that this
implies the networking configuration is OK. Does spdk need something
2. Try it on the latest master - Ben told me we had to revert a patch this
morning that went in last night that caused NVMe-oF issues. This
isn't related to your issue, but may be worth trying to cover our bases.
OK, just pulled a817ccf5 and see the same issue.
