ifconfig lists network devices (interfaces), not "cards". wifi0 is the
"master radio interface" and wlan0 is "virtual data interface". In most
cases, you can just ignore the existance of wifi0 and use wlan0. I use
multiple interface to clean up the implementation of virtual interfaces
(like WDS interfaces).
