I should have wrote multi-VAP mode, since that's what it really is, except for that it doesn't panic, unlike madwifi's similarly named mode. Wext.c blocks setting ESSID and BSSID for monitor interfaces - but there is nothing that prevents a monitor and a station interface to coexist on the same wmaster - and even though setting ESSID and BSSID on the monitor interface (call it "rtap0") is blocked, they still work on the station interface (for example, "wlan0"). (This multi-interface mode is exposed by the iw tool, as well as aircrack-ng's airmon-ng script, which essentially acts as a front-end for iw.)
