MII-tool question

Hi all,

Can mii-tool work on a 3c509?
When I run mii-tool, I get 
SIOCGMMPHY on 'eth0' failed: Operation not supported.
no MII interfaces found
I'm trying to enable the full duplex feature on the card.

primarily to hide the arbitrariness of the victim and the fact that
the innocent victim is a victim at all. If we know the victim to be
arbitrary, we cannot succeed in making him sacred; if we know the
victim to be innocent, the cycle of violence and the breakdown of
culture cannot be solved-as they were not solved in Athens, for
instance, by the innocent Socrates' death." First Things
