Subject: [net 10/15] net/mlx5: Disable devlink reload for multi port slave device
Date: Thu, 11 Feb 2021 18:56:36 -0800	[thread overview]
Message-ID: <20210212025641.323844-11-saeed@kernel.org> (raw)
In-Reply-To: <20210212025641.323844-1-saeed@kernel.org>

From: Shay Drory <shayd@nvidia.com>

Devlink reload can't be allowed on a multi port slave device, because
reload of slave device doesn't take effect.

The right flow is to disable devlink reload for multi port slave
device. Hence, disabling it in mlx5_core probing.

Fixes: 4383cfcc65e7 ("net/mlx5: Add devlink reload")
