Subject: [PATCH net-next v2 3/4] mlx5: become aware of when running as a bonding slave

I've been unable to get my hands on suitable supported hardware to date,
but I believe this ought to be all that is needed to enable the mlx5
driver to also work with bonding active-backup crypto offload passthru.
