Jason Gunthorpe 0f45e69d62 Verbs flow counters support
This series 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 define 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.
 
 In addition it presents the implementation of the generic counters interface.
 
 This will be 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.
 
 The API includes:
 1. create and destroyed API of a new counters objects
 2. read the counters values from HW
 
 Note:
 Attaching API to allow application to define the measurement points per objects
 is a user space only API and this data is passed to kernel when the counted
 object (e.g. flow) is created with the counters object.

====================
Verbs flow counters support

This series 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.

The API enables generic counters creation and define mapping to
association with a verbs object, the current mlx5 driver is 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.

In addition it presents the implementation of the generic counters
interface.

This will be 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.

The API includes:
1. create and destroyed API of a new counters objects
2. read the counters values from HW

Note:
Attaching API to allow application to define the measurement points per
objects is a user space only API and this data is passed to kernel when
the counted object (e.g. flow) is created with the counters object.
