Subject: [for-next V2 04/11] net/mlx5: E-Switch, Move mlx5e only logic outside E-Switch
From: Mark Bloch <markb@...lanox.com>
In our pursuit to cleanup e-switch sub-module from mlx5e specific code,
we move the functions that insert/remove the flow steering rules that
allow mlx5e representors to send packets directly to VFs into the EN
driver code.
