       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 PCM-
       CIA 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 card.

	      Specifies the set of interrupts that may be allocated by this driver.

	      Sets  the access speed of the shared memory window, in nanoseconds.  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  sup-
       port. 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 availability 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 modu-
       lation  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  dis-
       carded packet counters 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

       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.

       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.
