From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sasha Levin Subject: [PATCH AUTOSEL 4.14 10/35] net/mlx5: E-Switch, Fix esw manager vport indication for more vport commands Date: Wed, 24 Apr 2019 10:46:44 -0400 Message-ID: <20190424144709.30215-10-sashal@kernel.org> References: <20190424144709.30215-1-sashal@kernel.org> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20190424144709.30215-1-sashal@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org, stable@vger.kernel.org Cc: Omri Kahalon , Saeed Mahameed , Sasha Levin , netdev@vger.kernel.org, linux-rdma@vger.kernel.org List-Id: linux-rdma@vger.kernel.org From: Omri Kahalon [ Upstream commit eca4a928585ac08147e5cc8e2111ecbc6279ee31 ] Traditionally, the PF (Physical Function) which resides on vport 0 was the E-switch manager. Since the ECPF (Embedded CPU Physical Function), which resides on vport 0xfffe, was introduced as the E-Switch manager, the assumption that the E-switch manager is on vport 0 is incorrect. Since the eswitch code already uses the actual vport value, all we need is to always set other_vport=1.
