 This is not a bug, it's a side-effect of design. Until you bring the interf=
 ace up interrupts are not enabled, hence there is no way to see and respond=
  to the link change event. If you bring the port up just by doing an `ifcon=
 fig igbX up` and try it again you'll see the status will change.
