      We do not program the device into a usable state until it
      is upped so that we do not have to allocate resources (memory,
      etc.) while a device is down.
   
   I see.  So I assume that means all of the drivers will be updated to
   require this, rather than just the small number that now does?
   
That is not necessarily the case.  What is the case is that
you absolutely cannot assume that a non-UP interface will give
a valid link status.
