-          Connection 802.11b wireless network adapter.
-
-          See <file:Documentation/networking/README.ipw2100> for information on
-          the capabilities currently enabled in this driver and for tips
-          for debugging issues and problems.
-
-          In order to use this driver, you will need a firmware image for it.
-          You can obtain the firmware from
-          <http://ipw2100.sf.net/>.  Once you have the firmware image, you 
-          will need to place it in /lib/firmware.
-
-          You will also very likely need the Wireless Tools in order to
-          configure your card:
-
-          <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
-
-          It is recommended that you compile this driver as a module (M)
-          rather than built-in (Y). This driver requires firmware at device
-          initialization time, and when built-in this typically happens
-          before the filesystem is accessible (hence firmware will be
-          unavailable and initialization will fail). If you do choose to build
-          this driver into your kernel image, you can avoid this problem by
-          including the firmware and a firmware loader in an initramfs.

-          With this feature compiled into the driver, you can switch to 
-          promiscuous mode via the Wireless Tool's Monitor mode.  While in this
-          mode, no packets can be sent.

-        ---help---
-          This option will enable debug tracing output for the IPW2100.  
-
-          This will result in the kernel module being ~60k larger.  You can 
-          control which debug output is sent to the kernel log by setting the

-          /sys/bus/pci/drivers/ipw2100/debug_level
-
-          This entry will only exist if this option is enabled.

-        ---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
-
-config IPW2200_QOS
-        bool "Enable QoS support"
-        depends on IPW2200 && EXPERIMENTAL
-
-config IPW2200_DEBUG
-        bool "Enable full debugging output in IPW2200 module."
-        depends on IPW2200
-        ---help---
-          This option will enable low level debug tracing output for IPW2200.
-
-          Note, normal debug code is already compiled in. This low level
-          debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
-          will result in the kernel module being ~70 larger.  Most users
-          will typically not need this high verbosity debug information.
-
-          If you are not sure, say N here.

+          <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
+
+          It is recommended that you compile this driver as a module (M)
+          rather than built-in (Y). This driver requires firmware at device
+          initialization time, and when built-in this typically happens

-          This will result in the kernel module being ~70k larger.  You

-
-          For a list of values you can assign to debug_level, you
