[netdrvr] Remove superceded wireless driver aironet4500 

From the maintainer, Elmer Joandi(sp?):
	aironet4500 is superseded by cisco340 drivers (airo.c) by Ben Reed
and the  only strenght of my driver is that it allows to access absolutely
all registers on card. Which is useful for developers only. Besides there
is no normal interface to configure crypto in my driver, as the general
interface is not userfriendly at all. So in fact, I use Bens driver for my
ISP bussiness in general cases and my driver for troubleshooting.

depends on NET_RADIO && (PCI || ISA || PCMCIA)
---help---
www.aironet.com (recently bought by Cisco) makes these 802.11 DS
adapters. Driver by Elmer Joandi (elmer@ylenurme.ee).
Say Y here if you have such an adapter, and then say Y below to
the option that applies to your particular type of card (PCI, ISA,
or PCMCIA).
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_core. If you want to
compile it as a module, say M here and read
<file:Documentation/modules.txt> as well as
<file:Documentation/networking/net-modules.txt>.
quick config parameters:
SSID=tsunami - "The Password"
adhoc=1 there are no Access Points around
master=1 Adhoc master (the one who creates network
sync)
slave=1 Adhoc slave (btw, it is still forming own net
sometimes, and has problems with firmware...
change IbssJoinNetTimeout from /proc...)
channel=1..? meaningful in adhoc mode
If you have problems with screwing up card, both_bap_lock=1 is a
conservative value (performance hit 15%).
All other parameters can be set via the proc interface.
config AIRONET4500_NONCS
tristate "Aironet 4500/4800 ISA/PCI/PNP/365 support "

help
If you have an ISA, PCI or PCMCIA Aironet 4500/4800 wireless LAN
card, say Y here, and then also to the options below that apply
to you.
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_card. If you want to
compile it as a module, say M here and read
<file:Documentation/modules.txt>.
config AIRONET4500_PNP
bool "Aironet 4500/4800 PNP support "
depends on AIRONET4500_NONCS
help
If you have an ISA Aironet 4500/4800 card which you want to use in
PnP (Plug and Play) mode, say Y here. This is the recommended mode
for ISA cards. Remember however to enable the PnP jumper on the
board if you say Y here.
config AIRONET4500_PCI
bool "Aironet 4500/4800 PCI support "
depends on AIRONET4500_NONCS && PCI
help
If you have an PCI Aironet 4500/4800 card, say Y here.
config AIRONET4500_ISA
bool "Aironet 4500/4800 ISA broken support (EXPERIMENTAL)"
depends on AIRONET4500_NONCS && EXPERIMENTAL
help
If you have an ISA Aironet 4500/4800 card which you want to run in
non-PnP mode, say Y here. This is not recommended and does not work
correctly at this point. Say N.
config AIRONET4500_I365
bool "Aironet 4500/4800 I365 broken support (EXPERIMENTAL)"
depends on AIRONET4500_NONCS && EXPERIMENTAL
help
If you have a PCMCIA Aironet 4500/4800 card which you want to use
without the standard PCMCIA cardservices provided by the pcmcia-cs
package, say Y here. This is not recommended, so say N.
config AIRONET4500_PROC
tristate "Aironet 4500/4800 PROC interface "
depends on AIRONET4500 && m
---help---
If you say Y here (and to the "/proc file system" below), you will
be able to configure your Aironet card via the
/proc/sys/aironet4500 interface.
Additional info: look in <file:drivers/net/aironet4500_rid.c>.
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_proc. If you want to
compile it as a module, say M here and read
<file:Documentation/modules.txt>.
NOTE: the proc interface uses a lot of memory, so it is recommended
to compile it as a module and remove the module after
configuration.

november 99, integration with 2.3
17.12.99: finally, got SMP near-correct.
timing issues remain- on SMP box its 15% slower on tcp
