Staging: wavelan: delete the driver

It has sat in the staging directory since October of 2009, and no one
has stepped up to take it over, so odds are, no one cares about it
anymore.  So, it is now deleted as scheduled, and documented in the TODO
file.

---help---
The Lucent WaveLAN (formerly NCR and AT&T; or DEC RoamAbout DS) is
a Radio LAN (wireless Ethernet-like Local Area Network) using the
radio frequencies 900 MHz and 2.4 GHz.
If you want to use an ISA WaveLAN card under Linux, say Y and read
the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Some more specific
information is contained in
<file:Documentation/networking/wavelan.txt> and in the source code
<file:drivers/net/wireless/wavelan.p.h>.
You will also need the wireless tools package available from
<http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
Please read the man pages contained therein.
To compile this driver as a module, choose M here: the module will be
called wavelan.

select WIRELESS_EXT

help
Say Y here if you intend to attach an AT&T/Lucent Wavelan PCMCIA
(PC-card) wireless Ethernet networking card to your computer. This
driver is for the non-IEEE-802.11 Wavelan cards.
To compile this driver as a module, choose M here: the module will be
called wavelan_cs. If unsure, say N.

obj-$(CONFIG_PCMCIA_WAVELAN) += wavelan_cs.o
TODO:
- step up and maintain this driver to ensure that it continues
to work. Having the hardware for this is pretty much a
requirement. If this does not happen, the will be removed in
the 2.6.35 kernel release.
Please send patches to Greg Kroah-Hartman <greg@kroah.com>.

* The description of a later device, the

* the SCP and ISCP and also has an i82586 compatibility
