From 6a9764efb255f49a91e229799c38d5c1c9361987 Mon Sep 17 00:00:00 2001 From: Saeed Mahameed Date: Wed, 21 Dec 2016 17:24:35 +0200 Subject: [PATCH] net/mlx5e: Isolate open_channels from priv->params In order to have a clean separation between channels resources creation flows and current active mlx5e netdev parameters, make sure each resource creation function do not access priv->params, and only works with on a new fresh set of parameters. For this we add "new" mlx5e_params field to mlx5e_channels structure and use it down the road to mlx5e_open_{cq,rq,sq} and so on.
