I think it makes sense to allow a fixed phy carrier to be changed from
user space. However, i don't think you can easily plumb that to
.ndo_change_carrier(), since that is a MAC feature. You need to change
the fixed_phy_status to indicate the PHY has lost link, and then let
the usual mechanisms tell the MAC it is down and change the carrier
status.
