     wlconfig -- read/write wavelan config parameters

     wlconfig ifname [param value ...]

     The wlconfig utility can be used to read and set parameters for the
     NCR/AT&T Wavelan radio LAN	card.  Various parameters stored in the	non-
     volatile Parameter	Storage	Area (PSA) on the card can be modified with
     this program, replacing the DOS-based instconf.exe	program.  It can also
     be	used to	interrogate the	optional signal	strength cache which may have
     been compiled into	the driver.

     The ifname	parameter specifies the	wavelan	interface name (eg.  wl0).  If
     no	other arguments	are supplied, the current contents of the PSA are
     interpreted and displayed.

     The param and value arguments can be used to change the value of several
     parameters.  Any number of	param value pairs may be supplied.

	   param	    value

	   irq		    IRQ	value (used at next reset), may	be one of

	   mac		    Local MAC value (ethernet address).

	   macsel	    `soft' (as set by the `mac'	parameter) or
			    `default' (as set at the factory).

	   nwid		    The	NWID is	a 2-byte parameter passed to the
			    card's radio modem.	 NWIDs allow multiple logi-
			    cally discrete networks to operate independently
			    whilst occupying the same airspace.	 Packets with
			    a different	NWID are simply	ignored	by the modem.
			    In the hardware, NWIDs are stored long-term	in
			    non-volatile memory	(called	the PSA	or pro-
			    grammable storage area), and are loaded by soft-
			    ware into the radio	modem when the driver is ini-
			    tialized.  This sets the default NWID loaded at

	   currnwid	    This sets the current operating NWID (but does not
			    save it to the PSA).

	   cache	    The	driver may maintain a per interface fixed size
			    cache of signal strength, silence, and quality
			    levels, which are indexed by sender	MAC addresses.
			    Input packets are stored in	the cache, and when
			    received, the values stored	in the radio modem are
			    interrogated and stored.  There are	also two
			    sysctl values (iponly and multicast	only) which
			    can	be used	for filtering out some input packets.
			    By default,	the cache mechanism stores only	non-
			    unicast IP packets,	but this can be	changed	with
			    sysctl(8).	Each non-filtered input	packet causes
			    a cache update, hence one can monitor the antennae
			    signal strength to a remote	system.	 There are
			    three commands that	can be given as	values:	`raw',
			    which prints out the raw signal strength data as
			    found in the radio modem hardware value, `scale',
			    which scales the raw hardware values to 0..100%,
			    and	`zero' which clears out	the cache in case you
			    want to store new samples.

     Note that if the IRQ on the Wavelan card is incorrect, the	interface will
     be	configured, but	will not function.  The	wlconfig utility should	then
     be	used to	reconfigure the	card to	a sensible value.

     Set the NWID to 0x1234:

     # wlconfig	wl0 nwid 0x1234

     Show the current settings:

     # wlconfig	wl0
     Board type		   : ISA
     Base address options  : 0x300, 0x390, 0x3c0, 0x3e0
     Waitstates		   : 0
     Bus mode		   : ISA
     IRQ		   : 10
     Default MAC address   : 08:00:0e:20:3d:4b
     Soft MAC address	   : 00:00:00:00:00:00
     Current MAC address   : Default
     Adapter compatibility : PC-AT 2.4GHz
     Threshold preset	   : 1
     Call code required	   : NO
     Subband		   : 2425MHz
     Quality threshold	   : 3
     Hardware version	   : 0 (Rel1/Rel2)
     Network ID	enable	   : YES
     NWID		   : 0xdead
     Datalink security	   : NO
     Databus width	   : 16	(variable)
     Configuration state   : unconfigured
     CRC-16		   : 0x3c26
     CRC status		   : OK

     Print a scaled version of the signal strength cache:

     # wlconfig	wl0 cache scale

     wl(4), sysctl(8)

     This implementation of the	wlconfig utility is completely new, written
     for Hilink	Internet by Michael Smith, and updated by Jim Binkley &c.
