-          Saying Y here also enables the Wireless Extensions (creates
-          /proc/net/wireless and enables iwconfig access). The Wireless
-          Extension is a generic API allowing a driver to expose to the user
-          space configuration and statistics specific to common Wireless LANs.
-          The beauty of it is that a single set of tool can support all the
-          variations of Wireless LANs, regardless of their type (as long as
-          the driver supports Wireless Extension). Another advantage is that
-          these parameters may be changed on the fly without restarting the
-          driver (or Linux). If you wish to use Wireless Extensions with
-          wireless PCMCIA (PC-) cards, you need to say Y here; you can fetch
