Message-ID: <20190501215433.24047-14-saeedm@mellanox.com> Date: Wed, 1 May 2019 21:55:07 +0000 From: Saeed Mahameed <saeedm@...lanox.com> To: "David S. Miller" <davem@...emloft.net> CC: "netdev@...r.kernel.org" <netdev@...r.kernel.org>, Bodong Wang <bodong@...lanox.com>, Vu Pham <vuhuong@...lanox.com>, Parav Pandit <parav@...lanox.com>, Saeed Mahameed <saeedm@...lanox.com> Subject: [net-next V2 13/15] net/mlx5: E-Switch, Use getter to access all vport array From: Bodong Wang <bodong@...lanox.com> Some functions issue vport commands and access vport array using vport_index/vport_num interchangeably which is OK for VFs vports. However, this creates potential bug if those vports are not VFs (E.g, uplink, sf) where their vport_index don't equal to vport_num. Prepare code to access mlx5_vport structure using a getter function.
