Neither one actually works. Yeah; I had to recently patch wpa_supplicant to really disassociate at Jouni's suggestion; just telling the driver to disassoc isn't adequate in all cases, because some drivers will just try to reassoc. Instead, unlocking the BSSID and setting a bogus SSID will usually actually accomplish the disassociation in addition to the MLME disassoc...
