Not all ethernet drivers disable the PHY when you down the interface...
You can try to use:
ifconfig <int> media none

to shutdown the PHY, but the em driver on 9.1 doesn't have it, but re
(7.2-R and -current) and msk (-current) seems to have it...

Also, why do you want the led to go off?  Remeber, the led is just an
indication if there is a link established, not what will happen to the
packets that are received...
