rdma_resolve_addr(NULL,...) doesn't work in the current code. 

Are you suggesting allowing rdma_resolve_addr() with a NULL cm_id? 

The reason for not using rdma_resolve_addr() is to avoid having to 
allocate and free a cm_id each time we just want to find the local ib 
device, given a remote IP addr...
