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.

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. |
