From acff797cd187402d73cf9f290531a41250613294 Mon Sep 17 00:00:00 2001 From: Maor Gottlieb Date: Fri, 29 Apr 2016 01:36:37 +0300 Subject: [PATCH] net/mlx5e: Refactor mlx5e flow steering structs Slightly refactor and re-order the flow steering structs, tables and data-bases for better self-containment and flexibility to add more future steering phases (tables/rules/data bases) e.g: aRFS. Changes: 1. Move the vlan DB and address DB into their table structs. 2. Rename steering table structs to unique format: mlx5e_*_table, e.g: mlx5e_vlan_table.
