[PATCH net-next V2 0/4] mlx5e: Support recovery counter in reset

[Tariq Toukan]

Hi,

This series by Yael adds a recovery counter in ethtool, for any recovery
type during port reset cycle.
Series starts with some cleanup and refactoring patches.
New counter is added and exposed to ethtool stats in patch #4.

Regards,
Tariq

V2:
- Fix bad indentation failing the html build. (Stanislav Fomichev).
- Add review tags.

Yael Chemla (4):
  net/mlx5e: Ensure each counter group uses its PCAM bit
  net/mlx5e: Access PHY layer counter group as other counter groups
  net/mlx5e: Get counter group size by FW capability
  net/mlx5e: Expose port reset cycle recovery counter via ethtool

[PATCH net-next V2 1/4] net/mlx5e: Ensure each counter group uses its PCAM bit

[Tariq Toukan]

From: Yael Chemla <ychemla@nvidia.com>

The code was incorrectly relying on PCAM bit of ppcnt_statistical_group
for accessing per_lane_error_counters.
If ppcnt_statistical_group PCAM bit was not set, we would not read
per_lane_error_counters, even when its PCAM bit is set.
Given the existing device capabilities, it seems to cause no harm, so
this change primarily serves as cleanup.
