> mlx5e_xfrm_add_state() reads priv->ipsec and validates mode-dependent
> capabilities before blocking eswitch mode changes. A concurrent profile
> change can free the saved IPsec context and cause use-after-free.
>
> Move the mode block before the first context access and release it on
> all error paths. Keep the atomic acquire-placeholder path exempt, since
> it creates no hardware state and cannot take sleeping locks.
