> Why not provide resolving capabilities for plain rdma without ip stack?

Infiniband does not use IP addressing.  IP addresses require some sort of mapping.  The RDMA CM examines the IP address and must associate it with a specific RDMA device port.  If the IP address cannot be matched with a specific RDMA port, the mapping fails and an error is returned.

The verbs provider should just need to be updated to support native IB addressing.  Thanks for opening the issue to track that.
