Subject: [net-next 03/16] net/mlx5e: Hide all implementation details of mlx5e_rx_res
From: Maxim Mikityanskiy <maximmi@...dia.com>
This commit moves all implementation details of struct mlx5e_rx_res
under en/rx_res.c. All access to RX resources is now done using methods.
Encapsulating RX resources into an object allows for better
manageability, because all the implementation details are now in a
single place, and external code can use only a limited set of API
methods to init/teardown the whole thing, reconfigure RSS and LRO
parameters, connect TIRs to flow steering and activate/deactivate TIRs.
mlx5e_rx_res is self-contained and doesn't depend on struct mlx5e_priv
or include en.h.
