Some drivers and/or card firmware will not pass the control frames to 
libpcap for processing.  I know that the orinoco_cs drivers will report 
everything but control frames while in RFMON, while the wlan-ng and 
hostap drivers will report both management and control frames.

Not sure about the Cisco drivers, but if you really want control frames, 
I'd go with a Prism2 wireless card and the wlan-ng drivers.
