Recent versions of NetworkManager request that wpa_supplicant scan, but
receives scan results via SIOCGIWSCAN ioctl. That's no different than
running iwlist eth0 scan at the same time as wpa_supplicant.
NM trunk (what will be 0.7) uses the D-Bus interface to wpa_supplicant
and does all scanning through wpa_supplicant.
