mlx5-updates-2017-10-31 mlx5e stats groups
This series from Kamal introduces an important refactoring for mlx5e stats
handling, which groups the stats into generic groups structure which allows
to control the behavior and stats reporting per group in a modular way.
In the first patch Kamal introduces a new data type "mlx5e_stats_grp" This change
defines a new API to create a group of stats and simplifies the way of handling them.
This struct will define the following behavior per group:
- get_num_stats() - return the number of counters in the group.
- fill_strings() - fill counters strings within the group.
- fill_stats() - fill counters values within the group.
All other patches will be straight forward refactoring per stats group,
where Kamal will move each mlx5e stats group to use the new API.
The idea is to have better flexibility and modularity to add new counters,
all ethtool logic was rendered generic and loops through the generic stats groups and
calls the groups callbacks to figure out how and what to report back to user space.
Introducing new file en_stats.c to hold all the new stat groups logic and implementation.
Static structures (counters descriptors) moved from en_stats.h to en_stats.c which reduces
the mlx5_core binary footprint, originally reported and addressed by Stephen Hemminger:
("mlx5: fix space waste from ethtool descriptions") which was waived due to this re-design.
