Subject: [net 2/6] net/mlx5: Remove all auxiliary devices at the unregister event
Date: Thu, 26 Aug 2021 15:18:06 -0700	[thread overview]
Message-ID: <20210826221810.215968-3-saeed@kernel.org> (raw)
In-Reply-To: <20210826221810.215968-1-saeed@kernel.org>

From: Leon Romanovsky <leonro@nvidia.com>

The call to mlx5_unregister_device() means that mlx5_core driver is
removed. In such scenario, we need to disregard all other flags like
attach/detach and forcibly remove all auxiliary devices.

Fixes: a5ae8fc9058e ("net/mlx5e: Don't create devices during unload flow")
