+	  This is a driver for wireless RNDIS devices.
+	  These are USB based adapters found in devices such as:
+
+	  Buffalo WLI-U2-KG125S
+	  U.S. Robotics USR5421
+	  Belkin F5D7051
+	  Linksys WUSB54GSv2

+	  BT Voyager 1055
+	  Linksys WUSB54GSv1
+	  U.S. Robotics USR5420
+	  BUFFALO WLI-USB-G54
+
+	  All of these devices are based on Broadcom 4320 chip which is the
+	  only wireless RNDIS chip known to date.
+
+	  If you choose to build a module, it'll be called rndis_wlan.
