From ecf5bb796b992454c34f555e76c29360ed9b886d Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Tue, 24 Jan 2017 20:54:09 +0200 Subject: [PATCH] net/mlx5e: Add prefix for e-switch offloaded TC flow attributes Add esw_ prefix to the flow attributes attached to offloaded e-switch TC flows. This is a pre-step to add attributes to offloaded NIC TC flows. Also, save one pointer space by using gcc's zero size array, this would be beneficial for environments where 100Ks (or Ms) of flows are offloaded. This patch doesn't change any functionality.
