NAME
       wavelan - AT&T GIS WaveLAN ISA device driver

SYNOPSIS
       insmod wavelan_cs.o [io=B,B..] [ irq=I,I..] [name=N,N..]

DESCRIPTION
       wavelan	is  the	 low-level  device driver for the NCR / AT&T / Lucent
       WaveLAN ISA and Digital (DEC) RoamAbout DS wireless ethernet  adapter.
       This  driver is available as a module or might be compiled in the ker-
       nel. This driver supports multiple cards in both forms (up to  4)  and
       allocates  the  next  available	ethernet device (eth0..eth#) for each
       card found, unless a device name is explicitly specified (see  below).
       This  device name will be reported in the kernel log file with the MAC
       address, NWID and frequency used by the card.

PARAMETERS
       This section apply to the module form (parameters passed on  the	 ins-
       mod(8) command line). If the driver is included in the kernel, use the
       ether=IRQ,IO,NAME syntax on the kernel command line.

       io     Specify the list of base address where to	 search	 for  wavelan
	      cards (setting by dip switch on the card). If you don’t specify
	      any io address, the driver will scan 0x390 and 0x3E0 addresses,
	      which might conflict with other hardware...

       irq    Set  the	list  of  irq  that each wavelan card should use (the
	      value is saved in permanent storage for future use).

       name   Set the list of name to be used for each wavelan	cards  device
	      (name used by ifconfig(8)).

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

   NWID (or domain)
       Set  the	 network  ID [0 to FFFF] or disable it [off].  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.	 Fre-
       quency availability depend on the regulations...

   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 and Level threshold
       Enable you the define the quality and  level  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.

SPECIFIC NOTES
       This driver will fail to	 detect	 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.
