NAME
       wavelan_cs - AT&T GIS WaveLAN PCMCIA device driver

SYNOPSIS
       insmod wavelan_cs.o [irq_list=i,j...] [mem_speed=n]

DESCRIPTION
       wavelan_cs  is  the low-level Card Services driver for the
       NCR / AT&T / Lucent WaveLAN PCMCIA and Digital (DEC) Roam-
       About  DS  wireless ethernet adapter.  When this driver is
       attached to a card, it allocates the next available ether-
       net  device (eth0..eth#).  This device name will be passed
       on to cardmgr(8) for the card configuration, and  reported
       in the kernel log file with the MAC address, NWID and fre-
       quency used by the card.

PARAMETERS
       irq_list=i,j,...
              Specifies the set of interrupts that may  be  allo-
              cated by this driver.

       mem_speed=n
              Sets  the access speed of the shared memory window,
              in nanoseconds.  The default is 0 (i.e.,  no  extra
              wait states).

WIRELESS EXTENSIONS
       Use iwconfig(8) to manipulate wireless extensions.

   Network ID
       Set  the  network  ID  [0  to FFFF] or disable it [off] or
       reenable it [on].  As the NWID is stored in the card  Per-
       manent Storage Area, it will be reuse at any further invo-
       cation of the driver.

   Frequency & channels
       For the 2.4GHz 2.00 Hardware, you are able to set the fre-
       quency  by  specifying  one  of  the  10  defined channels
       (2.412, 2.422, 2.425, 2.4305, 2.432, 2.442, 2.452,  2.460,
       2.462 or 2.484) or directly by its value. The frequency is
       changed immediately and permanentely. Frequency availabil-
       ity depend on the regulations...

   Sensitivity
       Signal  level  threshold  for  packet reception [0 to 63].
       Should be set according to the ambiant noise level.

   Encryption key
       Set the encryption key [0  to  FFFF-FFFF-FFFF-FFFF].   Use
       [off]  and  [on]  to  disable  and  reenable  the hardware
       encryption.  This  feature  works  only  for  device  with
       encryption option (DES or AES).

   Statistics spy
       Set  a  list  of MAC addresses in the driver (up to 8) and
       get the last quality  of  link  for  each  of  those  (see
       iwspy(8)).

   /proc/net/wireless
       status  is the status reported by the modem.  Link quality
       reports the quality of the modulation on the  air  (direct
       sequence  spread  spectrum)  [max  = 16].  Level and Noise
       refer to the signal level and noise level [max = 64].  The
       crypt  discarded packet and misc discarded packet counters
       are not implemented.

PRIVATE IOCTL
       You may use iwpriv(8) to manipulate private ioctls.

   Quality threshold
       Enable you the define the quality threshold  used  by  the
       modem (packet below that level are discarded).

   Histogram
       This  functionality  allow to set a number of signal level
       intervals and to count the number of packets  received  in
       each  of  those defined intervals. This distribution might
       be used to calculate the mean value and standard deviation
       of the signal level.

OTHER FEATURES
       Hot unplug support.
       Power saving (use 'ifconfig down').

SPECIFIC NOTES
       This  driver  will  fail to load some non NCR/ATT&T/Lucent
       Wavelan cards. If it's your case, you  must  look  in  the
       source  code on how to add your card to the detection rou-
       tine.

       Some of the  mentioned  features  are  optional.  You  may
       enable  to  disable  them  by changing flags in the driver
       header and recompile.
