IB/rxe: Add port protocol stats
Expose new counters using the get_hw_stats callback.
We expose the following counters:
+---------------------+----------------------------------------+
| Name | Description |
|---------------------+----------------------------------------|
|sent_pkts | number of sent pkts |
|---------------------+----------------------------------------|
|rcvd_pkts | number of received packets |
|---------------------+----------------------------------------|
|out_of_sequence | number of errors due to packet |
| | transport sequence number |
|---------------------+----------------------------------------|
|duplicate_request | number of received duplicated packets. |
| | A request that previously executed is |
| | named duplicated. |
|---------------------+----------------------------------------|
|rcvd_rnr_err | number of received RNR by completer |
|---------------------+----------------------------------------|
|send_rnr_err | number of sent RNR by responder |
|---------------------+----------------------------------------|
|rcvd_seq_err | number of out of sequence packets |
| | received |
|---------------------+----------------------------------------|
|ack_deffered | number of deferred handling of ack |
| | packets. |
|---------------------+----------------------------------------|
|retry_exceeded_err | number of times retry exceeded |
|---------------------+----------------------------------------|
|completer_retry_err | number of times completer decided to |
| | retry |
|---------------------+----------------------------------------|
|send_err | number of failed send packet |
+---------------------+----------------------------------------+
