You cannot set any card to master mode this way, you have to use hostapd
to set up the access point interface. The documentation at
http://wireless.kernel.org/en/users/Documentation/hostapd should help. :-)

I'd also recommend using iw instead of iwconfig, see
http://wireless.kernel.org/en/users/Documentation/iw
