          most likely want to say N here.

+       ---help---
+          Enables the creation of a second interface prefixed 'rtap'. 
+          This second interface will provide every received in radiotap
+         format.
+
+          This is useful for performing wireless network analysis while
+          maintaining an active association.
+
+          Example usage:
+
+            % modprobe ipw2200 rtap_iface=1
+            % ifconfig rtap0 up
+            % tethereal -i rtap0
+
+          If you do not specify 'rtap_iface=1' as a module parameter then 
+          the rtap interface will not be created and you will need to turn 
+          it on via sysfs:
+       
+            % echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
