rnr_retry_count has no meaning in iWARP. There is no RNR message in the
iwarp protocol. For some iwarp devices (cxgb3 for
retry_count, I assume, is for connection establishment? For the Chelsio
devices, this is all up to the TCP stack and thus this counter is not
used. If there is no TCP listener, then the connection establishment
will fail immediately. If the node is not reachable, then normal TCP

We ran into this problem when testing rping over Intel/QLogic hardware:
[root@rdmaperf3 ~]# rping -s -a 172.31.2.103 -v
wait for CONNECTED state 10
connect error -1
cma event RDMA_CM_EVENT_REJECTED, error 28
[root@rdmaperf3 ~]#
[root@rdmaperf8 ~]# rping -c -a 172.31.2.103 -v -C 5

conn_param.retry_count = 10;
2) the qib driver enforces a maximum of 7 for retry_count. I don't
