Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

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.
