> Subject: [PATCH] net/mlx5: fix file path location of HW counters
> When debugging performance of a DPDK application the user may need to
> view the different statistics of DPDK(for example out_of_buffer) This can be
> enabled by using testpmd command 'show port xstats <port_id>' for
> example.
> The current implementation assumes legacy mode in which the counters are
> at <ibdev_path>/<port_id>/hw_counters/<file_name>.
> In switchdev mode the counters file is located right after the device name,
> hence resides at <ibdev_path>/hw_counters.
> The fix tries to open the path in the second location after a failure to open
> the file from the first location.
> Fixes: 9c0a9eed37f1 ("net/mlx5: switch to the names in the shared IB
> context")
