    Enable smfs software steering when switchdev is enabled
    
    Before this point, when switchdev is enabled, the software
    steering mode is not taken into consideration. This patch
    tries to enable the smfs software steering mode when the
    switchdev mode is enabled, and if it fails, a warning message
    would be printed indicating the failur of the proccess, and
    the software steering mode will not change from its current value.
