This series from Raed comes to allow user space applications to monitor real time traffic activity and events of the verbs objects it manages, e.g.: ibv_qp, ibv_wq, ibv_flow. This API enables generic counters creation and defines mapping to association with a verbs object, current mlx5 driver using this API for flow counters. With this API, an application can monitor the entire life cycle of object activity, defined here as a static counters attachment. This API also allows dynamic counters monitoring of measurement points for a partial period in the verbs object life cycle. The static counters attachment for flow counters is achieved by extending flow creation by adding a new flow count specification type which allows the user to associate a previously created flow counters using the generic verbs counters interface to the created flow, once associated the user could read statistics by using the read function of the generic counters interface. A detailed description of the API appears as part the man pages of the series. The API follows a detailed RFC and discussion that was in the mailing list. The matching kernel series was already sent into rdma-next for 4.18.
