I think we may have a different interpretation of what phylink's
mac_link_down() and mac_link_up() are supposed to be doing here.
Of course, you have read the documentation of these methods so are
fully aware of what they're supposed to do. So you are aware that
when inband mode is being used, forcing the link down may be
counter-productive depending on how the hardware works.
