NAME
       wvlan_cs - Lucent WaveLAN/IEEE 802.11 device driver

SYNOPSIS
       insmod  wvlan_cs.o  [irq_list=i,j,...]	[port_type=n]  [station_name=s]  [network_name=s]
       [channel=n]  [ap_density=n]  [medium_reservation=n]  [frag_threshold=n]	[transmit_rate=n]
       [eth=n] [mtu=n]

DESCRIPTION
       wvlan_cs is the low-level Card Services driver for the Lucent WaveLAN/IEEE 802.11 and com-
       patible (the NCR WaveLAN/IEEE 802.11, the Cabletron RoamAbout 802.11 DS,  the  Melco  WLI-
       PCM-L11) wireless ethernet adapters.  When this driver is attached to a card, it allocates
       the next available device (eth0..eth#).	This device name will be passed on to  cardmgr(8)
       for the card configuration, and reported in the kernel log.

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

       port_type=n
	      Select WaveLAN port type: [1] BSS - Basic Service Set (default), [2] WDS - Wireless
	      Distribution System, [3] Pseudo-IBSS - ad-hoc network (no AccessPoint, PtP).

       station_name=s
	      Sets the station name.  The default is card-configured.

       network_name=s
	      Sets the independent network  name  in  ad-hoc  mode.   Sets  the  desired  network
	      (desired	ESSID)	to connect to if using an access point.  The default is card-con-
	      figured.

       channel=n
	      Channel (frequency) for ad-hoc networks and is useless if using  an  access  point.
	      Valid range: [0-14] (depends on local restrictions) and defaults to [3]

       ap_density=n
	      Sets the access point density (sensitivity). This affects modem and roaming thresh-
	      olds.  [1] low density (default), [2] medium density, [3] high density.

       medium_reservation=n
	      Sets the medium reservation (RTS/CTS frame length), which  affects  the  number  of
	      octets  in  a  message  or  fragment  above which a RTS/CTS handshake is performed.
	      [500] hidden stations, [2347] no RTS/CTS (default). Valid range: [0-2347]

       frag_threshold=n
	      Defines the number of bytes used for the fragmentation boundary for  directed  mes-
	      sages  (Fragmentation length unicast message transmission).  [2346] is the default,
	      valid range: [256-2346] (even numbers only!).

       transmit_rate=n
	      Transmit rate control.  [1] fixed  low,  [2]  fixed  high,  [3]  auto  select  high
	      (default),  [4]  fixed  medium,  [5] fixed high, [6] auto select standard, [7] auto
	      select medium.

       eth=n  Network device naming. By default [1] devices are named eth#, set this  to  [0]  to
	      have devices named wvlan#.

       mtu=n  Maximum transfer unit.  [1500] is the default, valid range: [256-2296]

WIRELESS EXTENSIONS
       Use  iwconfig(8)  to manipulate wireless extensions.  You need a kernel which was compiled
       with CONFIG_NET_RADIO set.  It is recommended that you run at least  Linux  kernel  2.2.11
       and use wireless_tools 19.  Older version do not support all of the current commands.

   ESSID (network ID)
       Set the network ID of the desired network to connect to (with access point) or the name of
       your private ad-hoc network (no access point).

   Mode
       Set the operating mode to Ad-Hoc or Managed.  In managed mode, the card will try  to  con-
       nect  to  an  Access  Point, to get access to the infrastructure. In Ad-Hoc mode, the card
       doesn't require an Access Point and can communicate directly with its peers.

   Frequency & channels
       Channel (frequency) for ad-hoc networks. The frequency is changed immediately and is  only
       changeable  in ad-hoc network mode. You may enter a frequency value in the 2.4 GHz band or
       the channel number.
       Valid values: 2.412, 2.417, 2.422, 2.427, 2.432, 2.437, 2.442, 2.447, 2.452, 2.457, 2.462,
       2.467, 2.472 or 2.484 GHz (depends on local restrictions) and defaults to 2.422 GHz

   Sens
       Set  the  Access  Point	density (sensitivity). This affects modem and roaming thresholds.
       [1] low density (default), [2] medium density, [3] high density.

   Rts
       Sets the medium reservation threshold (RTS/CTS frame length), which affects the number  of
       octets in a message or fragment above which a RTS/CTS handshake is performed.
       Use  [500]  when  there	are  hidden  stations  or large number of nodes and [2347] for no
       RTS/CTS (default). Valid range: [0-2347]

   Frag
       Defines the number of bytes used for the  fragmentation	boundary  for  directed  messages
       (Fragmentation length unicast message transmission). To be used when you have interference
       on the radio, because it significantly decreases the performance.
       [2346] is the default, valid range: [256-2346].

   Rate
       Set the rate used for transmission (but not reception). You may want to set it to a  fixed
       value for high number of nodes.
       The  default  is auto, or you may use 1, 2, 5.5 or 11 Mb/s (of course, 2 Mb/s cards cannot
       get the higher speeds).

   Enc
       Set the encryption key [0 to FFFF-FFFF-FF].  Use [off] and [on] to  disable  and  reenable
       the hardware encryption. This feature works only for device with encryption option (Silver
       or Gold).
       The card has 4 different keys that you may select, and you can choose the default key  for
       transmission (see iwconfig(8)).

   Nick (station name)
       Set the station name (only used for debugging purpose).

   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.  Level and Noise refer to the signal level and
       noise level in dBm.

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

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

       It's currently not possible to use the WaveLAN/IEEE as a bridge (MAC level). This is not a
       restriction of the driver, the NIC firmware doesn't allow to send out packets with another
       source MAC address than its own (which is mandatory required for bridgeing to work).

       Also the WaveLAN/IEEE can be used to connect to an Access Point, but cannot be  an  Access
       Point itself (because lack of bridgeing).

THANKS
       I  would like to thank Lucent Technology for making the necessary information available to
       public. Thanks to Nico Valster and Jan Martejin at Lucent for technical support. Thanks to
       Frank  Bruegmann, who managed to get additional hardware for me so that I can now do tests
       in different environments. And thanks to Jean Tourrilhes for  many  patches  and  wireless
       kernel extensions.  Also many thanks to everybody who tested and helped me developing this
       driver :-)
