SYNOPSIS

       insmod     ray_cs    [essid=string]    [irq_mask=n]    [net_type=[0-1]]
       [ray_debug=[0-5]]        [phy_addr=xNNNNNNNNNNNN]         [hop_dwell=n]

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.
