NAME
       ray_cs - Raylink wireless LAN - PCMCIA card device driver

SYNOPSIS
       insmod  ray_cs  [essid=string]  [irq_mask=n]  [net_type=[0-1]]  [ray_debug=[0-5]]  [phy_addr=xNNNNNNNNNNNN] [hop_dwell=n] [beacon_period=n]
       [psm=[0-1]] [translate=[0-1]] [country=[1-8]] [sniffer=[0-1]] [bc=[0-1]]

DESCRIPTION
       ray_cs is the low level Card Services device driver for the Raylink wireless LAN PCMCIA adapter.  It is normally  loaded  automatically	by
       card services according to the parameters specified in /etc/pcmcia/ray_cs.opts.

PARAMETERS
       essid=string
	      ESS ID - network name to join string with maximum length of 32 chars default value = "LINUX"

       irq_mask=n
	      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.

       net_type=n
	      0 = adhoc network (default) 1 = infrastructure

       ray_debug=n
	      (0-5) larger values for more verbose logging.

       phy_addr=string
	      string of 12 hex digits containing new MAC address.  must be started with x e.g. x00008f123456

       hop_dwell=n
	      hop dwell time in Kilo-microseconds legal values = 16,32,64,128(default),256

       beacon_period=n
	      Beacon period in Kilo-microseconds.
	      Legal values = 16,32,64,128,256(default) must be integer multiple of hop dwell.

       psm=n  Power save mode
	      0 = continuously active
	      1 = power save mode (significantly slower)

       bc=n   Power save mode
	      0 = 802.11 timing
	      1 = 802.11 modified timing.  Interframe spacing is slowed down for compatibility with older Breezecom access points.

       translate
	      0 = no translation (encapsulate frames)
	      1 = translation (default)

       country=n
	      Country code
	      1 = USA (default)
	      2 = Europe
	      3 = Japan
	      4 = Korea
	      5 = Spain
	      6 = France
	      7 = Israel
	      8 = Australia

       sniffer=n
	      0 = normal network interface - 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.  This is
	      because linux has no knowledge of 802.11 headers and cannot parse them correctly.  Note that  tcpdump  does  not	understand  802.11
	      headers, either so it can't interpret the contents, but it can record to a file.

       BUGS   ray_cs can lock the machine if the card is pulled out while active.  I have never observed a crash if card is deactivated as follows
	      before removal:
	      ifconfig eth0 down
	      The above command assumes that the Raylink card is configured as eth0.

	      This driver only does encapsulation of ethernet frames within 802.11 frames.  Most vendors, including  Raytheon,	are  moving  to  a
	      frame translation method.  Translation support has been started, but is not yet functional.

	      Support for defragmenting frames is not yet tested.

	      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.
