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. |
