In linux kernel since version 2.6.12  
Support for wireless LANs and everything having to do with radio,
but not with amateur radio or FM broadcasting.

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
the tools from

Some user-level drivers for scarab devices which don't require
special kernel support are available from
<ftp://shadow.cabi.net/pub/Linux/>.
