Subject: [PATCH net-next 08/12] net/mlx5: Register devlink ports for satellite PFs
Date: Thu, 21 May 2026 14:08:39 +0300 [thread overview]
Message-ID: <20260521110843.367329-9-tariqt@nvidia.com> (raw)
In-Reply-To: <20260521110843.367329-1-tariqt@nvidia.com>
From: Moshe Shemesh <moshe@nvidia.com>
Include satellite PFs in mlx5_eswitch_is_pf_vf_vport() so they receive
the standard PF/VF devlink port operations. Update
mlx5_esw_devlink_port_supported() and devlink port attribute setup to
register SPF devlink ports with controller number and PF number.
Add mlx5_esw_spf_vport_to_idx() to look up the SPF array index by vport
number, and mlx5_esw_is_spf_vport() boolean wrapper to identify
satellite PF vports.
