The conn_qual (port) is less then 1024 and rdma_cma returns EPERM.

If you are calling dat_psp_create() with a conn_qual less then 1024 it 
will fail.

If calling dat_psp_create_any(), the seed value is 1000 so you will get 
some warning messages until it hits a valid port. This is not an error 
just a warning. The call should actually return DAT_SUCCESS along with a 
valid conn_qual. I will change the seed value to 1024 in the next release.
