> Subject: [PATCH v3 4/6] net/mlx5: flow counters mlx5 glue library update
> 

How about: "net/mlx5: add new flow counter verbs API to glue library

> This part of patchset updates the mlx5 glue library, new counter support
> function pointers are added to the glue linking structure mlx5_glue. This
> structure now contains the pointers to the both versions of counter
> supporting functions due to compatibility issues. Depending on configuration
> flags the functions perform actual Verbs library calls or return an error with
> meaning "feature is not supported" (NULL or ENOTSUP).
> 

>From previous patch comments, this patch should declare the new macro (V45)
