From e53a9d26cf80565cfb7172fc52a0dfac73613a0f Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Mon, 28 Oct 2019 23:35:30 +0000 Subject: IB/mlx5: Introduce and use mlx5_core_is_vf() Instead of deciding a given device is virtual function or not based on a device is PF or not, use already defined MLX5_COREDEV_VF by introducing an helper API mlx5_core_is_vf(). This enables to clearly identify PF, VF and non virtual functions.

Current configuration is stored on mlx5_core_dev and exposed to user through the cmode runtime devlink param. Changing configuration requires changing the cmode driverinit devlink param and calling devlink reload.
