       wavelan_cs - AT&T GIS WaveLAN PCMCIA device driver

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

       wavelan_cs  is  the low-level Card Services driver for the NCR / AT&T /
       Lucent WaveLAN PCMCIA and Digital (DEC) RoamAbout DS wireless  ethernet
       adapter.  When this driver is attached to a card, it allocates the next
       available ethernet 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 frequency  used  by  the

              Specifies  the  set  of interrupts that may be allocated by this

              Sets the access speed of the shared memory window,  in  nanosec-
              onds.  The default is 0 (i.e., no extra wait states).

              Enables or disables roaming mode.  The default is 1 (roam).

       Use iwconfig(8) to manipulate wireless extensions.

       Set  the  operating mode to Ad-Hoc or Managed.  This in fact disable or
       enable roaming support. This setting is not saved in hardware.

   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 Permanent Storage Area, it will be
       reuse at any further invocation of the driver.

   Frequency && channels
       For the 2.4GHz 2.00 Hardware, you are able  to  set  the  frequency  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 avail-
       ability depend on the regulations...

       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)).

       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 coun-
       ters are not implemented.

       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).

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

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

       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 routine.

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

       This  man  page describes the standalone PCMCIA drivers provided by the
       pcmcia-cs source, not the PCMCIA kernel driver support that is included
       in  the 2.4 (and later) linux kernel.  While the kernel PCMCIA code has
       the same functionality as the driver  side  of  the  standalone  PCMCIA
       package,  there are some important differences.  Therefore, some or all
       of this documentation might not apply to the kernel drivers.
