From e537fcf35c72c352a3428f5ec0978fd66002f11f Mon Sep 17 00:00:00 2001 From: Alaa Hleihel Date: Sun, 10 May 2020 15:03:52 -0400 Subject: [PATCH 075/312] [netdrv] net/mlx5: Introduce and use mlx5_esw_is_manager_vport() Message-id: <20200510150452.10307-28-ahleihel@redhat.com> Patchwork-id: 306652 Patchwork-instance: patchwork O-Subject: [RHEL8.3 BZ 1789380 v2 27/87] net/mlx5: Introduce and use mlx5_esw_is_manager_vport() Bugzilla: 1789380 RH-Acked-by: Kamal Heib RH-Acked-by: Jarod Wilson RH-Acked-by: Tony Camuso RH-Acked-by: Jonathan Toppins Bugzilla: http://bugzilla.redhat.com/1789380 Upstream: v5.5-rc1 commit ea2300e02a71207b11111a44cbe7185a94f78a72 Author: Parav Pandit Date: Mon Oct 28 23:35:05 2019 +0000 net/mlx5: Introduce and use mlx5_esw_is_manager_vport() Currently esw_enable_vport() does vport check for zero to enable drop counters regardless of execution on ECPF/PF. While esw_disable_vport() considers such scenario. To keep consistency across code for checking for manager_vport, introduce and use mlx5_esw_is_manager_vport() to check if a specified vport is eswitch manager vport or not.
