IB/mlx5: Add port protocol stats
Expose new counters using the get protocol stats callback.
We expose the following counters:
|------------------------------------------------------------------------|
| Name | IB | EN | Description |
|------------------------------------------------------------------------|
|rx_write_requests | + | - | Number of received WRITE requests for |
| | | | the associated QP. |
|------------------------------------------------------------------------|
|rx_read_requests | + | - | Number of received READ requests for |
| | | | the associated QP. |
|------------------------------------------------------------------------|
|rx_atomic_requests | + | - | Number of received ATOMIC requests for |
| | | | the associated QP. |
|------------------------------------------------------------------------|
|out_of_buffer | + | + | Number of drops occurred due to lack |
| | | | of WQE for the associated QPs/RQs. |
|------------------------------------------------------------------------|
|out_of_sequence | + | - | Number of errors in the packet |
| | | | transport sequence number |
|------------------------------------------------------------------------|
|duplicate_request | + | + | Number of received duplicated packets. |
| | | | A request that previously executed is |
| | | | named duplicated. |
|------------------------------------------------------------------------|
|rnr_nak_retry_err | + | + | Number of received RNR NAC packets. |
| | | | The QP retry limit did not exceed. |
|------------------------------------------------------------------------|
|packet_seq_err | + | + | Number of received NAK - sequence error|
| | | | packets. The QP retry limit did not |
| | | | exceed. |
|------------------------------------------------------------------------|
|implied_nak_err | + | + | Number of times the requester detected |
| | | | an ACK with a PSN larger than expected |
| | | | PSN for RDMA READ or ATOMIC response |
| | | | The QP retry limit did not exceed. |
|------------------------------------------------------------------------|
|local_ack_timeout_err| + | - | Number of NO ACK responses from |
| | | | responder within timer interval. |
| | | | The QP retry limit did not exceed. |
|------------------------------------------------------------------------|
Counters are available if all of them are supported.
