There is also ethtool. mii-tool does support the card AFAIK (shows the
right state at least for me) but with anything other then ethtool I
haven't managed to get the mode to stick (it kept reseting).
You also need to set it to autoneg off otherwise the mode is setting by
the highest the two sides support (if its on auto and doesn't choose
full duplex then maybe you other side doesn't support it).
BTW I was told that rtl8139 based cards don't support full duplex in
hardware despite claiming so. Don't know if thats true though.
