Raylink wireless LAN card
=========================
September 21, 1999
Copyright |copy| 1998 Corey Thomas (corey@world.std.com)
This file is the documentation for the Raylink Wireless LAN card driver for
Linux. The Raylink wireless LAN card is a PCMCIA card which provides IEEE
802.11 compatible wireless network connectivity at 1 and 2 megabits/second.
See http://www.raytheon.com/micro/raylink/ for more information on the Raylink
card. This driver is in early development and does have bugs. See the known
bugs and limitations at the end of this document for more information.
This driver also works with WebGear's Aviator 2.4 and Aviator Pro
wireless LAN cards.
As of kernel 2.3.18, the ray_cs driver is part of the Linux kernel
source. My web page for the development of ray_cs is at
http://web.ralinktech.com/ralink/Home/Support/Linux.html
and I can be emailed at corey@world.std.com
The kernel driver is based on ray_cs-1.62.tgz
The driver at my web page is intended to be used as an add on to
David Hinds pcmcia package. All the command line parameters are
available when compiled as a module. When built into the kernel, only
the essid= string parameter is available via the kernel command line.
This will change after the method of sorting out parameters for all
the PCMCIA drivers is agreed upon. If you must have a built in driver
with nondefault parameters, they can be edited in
/usr/src/linux/drivers/net/pcmcia/ray_cs.c. Searching for module_param
will find them all.
Information on card services is available at:
http://pcmcia-cs.sourceforge.net/
Card services user programs are still required for PCMCIA devices.
pcmcia-cs-3.1.1 or greater is required for the kernel version of
the driver.
Currently, ray_cs is not part of David Hinds card services package,
so the following magic is required.
At the end of the /etc/pcmcia/config.opts file, add the line:
source ./ray_cs.opts
This will make card services read the ray_cs.opts file
when starting. Create the file /etc/pcmcia/ray_cs.opts containing the
following::
#### start of /etc/pcmcia/ray_cs.opts ###################
# Configuration options for Raylink Wireless LAN PCMCIA card
device "ray_cs"
class "network" module "misc/ray_cs"
card "RayLink PC Card WLAN Adapter"
manfid 0x01a6, 0x0000
bind "ray_cs"
module "misc/ray_cs" opts ""
#### end of /etc/pcmcia/ray_cs.opts #####################
To join an existing network with
different parameters, contact the network administrator for the
configuration information, and edit /etc/pcmcia/ray_cs.opts.
Add the parameters below between the empty quotes.
Parameters for ray_cs driver which may be specified in ray_cs.opts:
=============== =============== =============================================
bc integer 0 = normal mode (802.11 timing),
1 = slow down inter frame timing to allow
operation with older breezecom access
points.
beacon_period integer beacon period in Kilo-microseconds,
legal values = must be integer multiple
of hop dwell
default = 256
country integer 1 = USA (default),
2 = Europe,
3 = Japan,
4 = Korea,
5 = Spain,
6 = France,
7 = Israel,
8 = Australia
essid string ESS ID - network name to join
string with maximum length of 32 chars
default value = "ADHOC_ESSID"
hop_dwell integer hop dwell time in Kilo-microseconds
legal values = 16,32,64,128(default),256
irq_mask integer linux standard 16 bit value 1bit/IRQ
lsb is IRQ 0, bit 1 is IRQ 1 etc.
Used to restrict choice of IRQ's to use.
Recommended method for controlling
interrupts is in /etc/pcmcia/config.opts
net_type integer 0 (default) = adhoc network,
1 = infrastructure
phy_addr string string containing new MAC address in
hex, must start with x eg
x00008f123456
psm integer 0 = continuously active,
1 = power save mode (not useful yet)
pc_debug integer (0-5) larger values for more verbose
logging. Replaces ray_debug.
ray_debug integer Replaced with pc_debug
ray_mem_speed integer defaults to 500
sniffer integer 0 = not sniffer (default),
1 = sniffer which can be used to record all
network traffic using tcpdump or similar,
but no normal network use is allowed.
translate integer 0 = no translation (encapsulate frames),
1 = translation (RFC1042/802.1)
=============== =============== =============================================
More on sniffer mode:
tcpdump does not understand 802.11 headers, so it can't
interpret the contents, but it can record to a file. This is only
useful for debugging 802.11 lowlevel protocols that are not visible to
linux. If you want to watch ftp xfers, or do similar things, you
don't need to use sniffer mode. Also, some packet types are never
sent up by the card, so you will never see them (ack, rts, cts, probe
etc.) There is a simple program (showcap) included in the ray_cs
package which parses the 802.11 headers.
Known Problems and missing features
Does not work with non x86
Does not work with SMP
Support for defragmenting frames is not yet debugged, and in
fact is known to not work. I have never encountered a net set
up to fragment, but still, it should be fixed.
The ioctl support is incomplete. The hardware address cannot be set
using ifconfig yet. If a different hardware address is needed, it may
be set using the phy_addr parameter in ray_cs.opts. This requires
a card insertion to take effect.

Shared driver code for IEEE 802.11b wireless cards based on
Intersil Prism2/2.5/3 chipset. This driver supports so called
Host AP mode that allows the card to act as an IEEE 802.11
access point.
See <http://hostap.epitest.fi/> for more information about the
Host AP driver configuration and tools. This site includes
information and tools (hostapd and wpa_supplicant) for WPA/WPA2
support.
This option includes the base Host AP driver code that is shared by

The driver can be compiled as a module and it will be called
hostap.

config HERMES
tristate "Hermes chipset 802.11b support (Orinoco/Prism2/Symbol)"

select CFG80211_WEXT_EXPORT

help
A driver for 802.11b wireless cards based on the "Hermes" or
Intersil HFA384x (Prism 2) MAC controller. This includes the vast
majority of the PCMCIA 802.11b cards (which are nearly all rebadges)
- except for the Cisco/Aironet cards. Cards supported include the
Apple Airport (not a PCMCIA card), WavelanIEEE/Orinoco,
Cabletron/EnteraSys Roamabout, ELSA AirLancer, MELCO Buffalo, Avaya,
IBM High Rate Wireless, Farralon Syyline, Samsung MagicLAN, Netgear
MA401, LinkSys WPC-11, D-Link DWL-650, 3Com AirConnect, Intel
IPW2011, and Symbol Spectrum24 High Rate amongst others.
This option includes the guts of the driver, but in order to
actually use a card you will also need to enable support for PCMCIA
Hermes cards, PLX9052 based PCI adaptors or the Apple Airport below.
You will also very likely also need the Wireless Tools in order to
configure your card and that /etc/pcmcia/wireless.opts works :
<https://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>
config HERMES_PRISM
bool "Support Prism 2/2.5 chipset"
depends on HERMES
help
Say Y to enable support for Prism 2 and 2.5 chipsets. These
chipsets are better handled by the hostap driver. This driver
would not support WPA or firmware download for Prism chipset.
If you are not sure, say N.
config HERMES_CACHE_FW_ON_INIT
bool "Cache Hermes firmware on driver initialisation"
depends on HERMES
default y
help
Say Y to cache any firmware required by the Hermes drivers
on startup. The firmware will remain cached until the
driver is unloaded. The cache uses 64K of RAM.
Otherwise load the firmware from userspace as required. In
this case the driver should be unloaded and restarted
whenever the firmware is changed.
If you are not sure, say Y.
config APPLE_AIRPORT
tristate "Apple Airport support (built-in)"
depends on PPC_PMAC && HERMES
help
Say Y here to support the Airport 802.11b wireless Ethernet hardware
built into the Macintosh iBook and other recent PowerPC-based
Macintosh machines. This is essentially a Lucent Orinoco card with
a non-standard interface.
This driver does not support the Airport Extreme (802.11b/g). Use
the BCM43xx driver for Airport Extreme cards.
config PLX_HERMES
tristate "Hermes in PLX9052 based PCI adaptor support (Netgear MA301 etc.)"
depends on PCI && HERMES
help
Enable support for PCMCIA cards supported by the "Hermes" (aka
orinoco) driver when used in PLX9052 based PCI adaptors. These
adaptors are not a full PCMCIA controller but act as a more limited
PCI <-> PCMCIA bridge. Several vendors sell such adaptors so that
802.11b PCMCIA cards can be used in desktop machines. The Netgear
MA301 is such an adaptor.
config TMD_HERMES
tristate "Hermes in TMD7160 based PCI adaptor support"
depends on PCI && HERMES
help
Enable support for PCMCIA cards supported by the "Hermes" (aka
orinoco) driver when used in TMD7160 based PCI adaptors. These
adaptors are not a full PCMCIA controller but act as a more limited
PCI <-> PCMCIA bridge. Several vendors sell such adaptors so that
802.11b PCMCIA cards can be used in desktop machines.
config NORTEL_HERMES
tristate "Nortel emobility PCI adaptor support"
depends on PCI && HERMES
help
Enable support for PCMCIA cards supported by the "Hermes" (aka
orinoco) driver when used in Nortel emobility PCI adaptors. These
adaptors are not full PCMCIA controllers, but act as a more limited
PCI <-> PCMCIA bridge.
config PCI_HERMES
tristate "Prism 2.5 PCI 802.11b adaptor support"
depends on PCI && HERMES && HERMES_PRISM
help
Enable support for PCI and mini-PCI 802.11b wireless NICs based on
the Prism 2.5 chipset. These are true PCI cards, not the 802.11b
PCMCIA cards bundled with PCI<->PCMCIA adaptors which are also
common. Some of the built-in wireless adaptors in laptops are of
this variety.
config PCMCIA_HERMES
tristate "Hermes PCMCIA card support"
depends on PCMCIA && HERMES && HAS_IOPORT_MAP
help
A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and
others). It should also be usable on various Prism II based cards
such as the Linksys, D-Link and Farallon Skyline. It should also
work on Symbol cards such as the 3Com AirConnect and Ericsson WLAN.
You will very likely need the Wireless Tools in order to
configure your card and that /etc/pcmcia/wireless.opts works:
<https://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
config PCMCIA_SPECTRUM
tristate "Symbol Spectrum24 Trilogy PCMCIA card support"
depends on PCMCIA && HERMES && HAS_IOPORT_MAP
help
This is a driver for 802.11b cards using RAM-loadable Symbol
firmware, such as Symbol Wireless Networker LA4100, CompactFlash
cards by Socket Communications and Intel PRO/Wireless 2011B.
This driver requires firmware download on startup. Utilities
for downloading Symbol firmware are available at
<http://sourceforge.net/projects/orinoco/>
config ORINOCO_USB
tristate "Agere Orinoco USB support"
depends on USB && HERMES
select FW_LOADER
help
This driver is for USB versions of the Agere Orinoco card.

* Here's the general details on how the PLX9052 adapter works:
*
* - Two PCI I/O address spaces, one 0x80 long which contains the
* PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA
* slot I/O address space.
*
* - One PCI memory address space, mapped to the PCMCIA attribute space
* (containing the CIS).
*
* Using the later, you can read through the CIS data to make sure the
* card is compatible with the driver. Keep in mind that the PCMCIA
* spec specifies the CIS as the lower 8 bits of each word read from
* the CIS, so to read the bytes of the CIS, read every other byte
* (0,2,4,...). Passing that test, you need to enable the I/O address
* space on the PCMCIA card via the PCMCIA COR register. This is the
* first byte following the CIS. In my case (which may not have any
* relation to what's on the PRISM2 cards), COR was at offset 0x800
* within the PCI memory space. Write 0x41 to the COR register to
* enable I/O mode and to select level triggered interrupts. To
* confirm you actually succeeded, read the COR register back and make
* sure it actually got set to 0x41, in case you have an unexpected
* card inserted.
*
* Following that, you can treat the second PCI I/O address space (the
* one that's not 0x80 in length) as the PCMCIA I/O space.
*
* Note that in the Eumitcom's source for their drivers, they register
* the interrupt as edge triggered when registering it with the
* Windows kernel. I don't recall how to register edge triggered on
* Linux (if it can be done at all). But in some experimentation, I
* don't see much operational difference between using either
* interrupt mode. Don't mess with the interrupt mode in the COR
* register though, as the PLX9052 wants level triggers with the way
* the serial EEPROM configures it on the WL11000.
*
* There's some other little quirks related to timing that I bumped
* into, but I don't recall right now. Also, there's two variants of
* the WL11000 I've seen, revision A1 and T2. These seem to differ
* slightly in the timings configured in the wait-state generator in
* the PLX9052. There have also been some comments from Eumitcom that
* cards shouldn't be hot swapped, apparently due to risk of cooking
* the PLX9052. I'm unsure why they believe this, as I can't see
* anything in the design that would really cause a problem, except
* for crashing drivers not written to expect it. And having developed
* drivers for the WL11000, I'd say it's quite tricky to write code
* that will successfully deal with a hot unplug. Very odd things
* happen on the I/O side of things. But anyway, be warned. Despite
* that, I've hot-swapped a number of times during debugging and
* driver development for various reasons (stuck WAIT# line after the
* radio card's firmware locks up).

This is a driver for wireless RNDIS devices.
These are USB based adapters found in devices such as:
Buffalo WLI-U2-KG125S
U.S. Robotics USR5421
Belkin F5D7051
Linksys WUSB54GSv2
Linksys WUSB54GSC
Asus WL169gE
Eminent EM4045
BT Voyager 1055
Linksys WUSB54GSv1
U.S. Robotics USR5420
BUFFALO WLI-USB-G54
All of these devices are based on Broadcom 4320 chip which is the
only wireless RNDIS chip known to date.
If you choose to build a module, it'll be called rndis_wlan.
