Say Y here if you have a PCMCIA Aironet 4500/4800 card which you
want to use with the standard PCMCIA cardservices provided by the
pcmcia-cs package.
This driver is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called aironet4500_cs. If you want to

-------------
1) Bring other kernel Wireless LAN drivers here
Already done :
o hermes.c/orinoco.c -> Wavelan IEEE driver + Airport driver
o airo.c/airo_cs.c -> Ben's Aironet driver
o wavelan.c -> old Wavelan ISA driver
o wavelan_cs.c -> old Wavelan Pcmcia driver
o netwave_cs.c -> Netwave Pcmcia driver
Drivers likely to go :
o ray_cs.c -> Raytheon/Aviator driver (maintainer MIA)
Drivers I have absolutely no control over :
o arlan.c -> old Aironet Arlan 655 (need to ask Elmer)
o aironet4500_xxx.c -> Elmer's Aironet driver (need to ask Elmer)
o strip.c -> Metricom's stuff. Not a wlan. Hum...
ETA : Kernel 2.5.X
Completed
2) Bring new Wireless LAN driver not yet in the kernel there
See my web page for details
In particular : HostAP
3) Misc
o Mark wavelan, wavelan_cs, netwave_cs drivers as obsolete
o Maybe arlan.c, ray_cs.c and strip.c also deserve to be obsolete
o Use new Probe/module stuff in wavelan.c
o New Wireless Extension API (pending)
