    Subject[PATCH 5.14 269/334] net/mlx5: Remove all auxiliary devices at the unregister event
    Date
    From: Leon Romanovsky <leonro@nvidia.com>

    [ Upstream commit 8e7e2e8ed0e251138926838b7933f8eb6dd56b12 ]

    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")
