net/mlx5e: Split SW group counters update function
Browse files Browse the repository at this point in the history 
SW group counter update function aggregates sw stats out of many
mlx5e_*_stats resides in a given mlx5e_channel_stats struct.
Split the function into a few helper functions.

This will be used later in the series to calculate specific
mlx5e_*_stats which are not defined inside mlx5e_channel_stats.
