+BT Commands:
+	The blinding table (BT) contains a list of mac addresses that should be
+	ignored by the firmware.  It is primarily used for debugging and
+	testing networks.  It can be edited and inspected with the following
+	commands:
+
+	iwpriv ethX bt_reset
+	iwpriv ethX bt_add <mac_address>
+	iwpriv ethX bt_del <mac_address>
+	iwpriv ethX bt_list <id>
+
+FWT Commands:
+	The forwarding table (FWT) is a feature used to manage mesh network
+	routing in the firmware.  The FWT is essentially a routing table that
+	associates a destination mac address (da) with a next hop receiver
+	address (ra).  The FWT can be inspected and edited with the following
+	iwpriv commands, which are described in greater detail below.
+	Eventually, the table will be automatically maintained by a custom
+	routing protocol.
+
+	NOTE: FWT commands replace the previous DFT commands.  What were the DFT
+	commands?, you might ask.  They were an earlier API to the firmware that
+	implemented a simple MAC-layer forwarding mechanism.  In the unlikely
+	event that you were using these commands, you must migrate to the new
+	FWT commands which can be used to achieve the same functionality.
+
+	iwpriv ethX fwt_add [parameters]
+	iwpriv ethX fwt_del [parameters]
+	iwpriv ethX fwt_lookup [parameters]
+	iwpriv ethX fwt_list [parameters]
+	iwpriv ethX fwt_list_route [parameters]
+	iwpriv ethX fwt_list_neigh [parameters]
+	iwpriv ethX fwt_reset [parameters]
+	iwpriv ethX fwt_cleanup
+	iwpriv ethX fwt_time
+
+MESH Commands:
+

+	routing protocol.  The following commands are supported:
+
+	iwpriv ethX mesh_get_ttl
+	iwpriv ethX mesh_set_ttl ttl

+
+fwt_add
+	This command is used to insert an entry into the FWT table. The list of
+	parameters must follow the following structure:
+
+	iwpriv ethX fwt_add da ra [metric dir ssn dsn hopcount ttl expiration sleepmode snr]
+
+	The parameters between brackets are optional, but they must appear in
+	the order specified.  For example, if you want to specify the metric,
+	you must also specify the dir, ssn, and dsn but you need not specify the
+	hopcount, expiration, sleepmode, or snr.  Any unspecified parameters
+	will be assigned the defaults specified below.
+
+	The different parameters are:-
+		da		-- DA MAC address in the form 00:11:22:33:44:55
+		ra		-- RA MAC address in the form 00:11:22:33:44:55
+		metric		-- route metric (cost: smaller-metric routes are
+				   preferred, default is 0)
+		dir		-- direction (1 for direct, 0 for reverse,
+				   default is 1)
+		ssn		-- Source Sequence Number (time at the RA for
+				   reverse routes.  Default is 0)
+		dsn		-- Destination Sequence Number (time at the DA
+				   for direct routes.  Default is 0)
+		hopcount	-- hop count (currently unused, default is 0)
+		ttl		-- TTL (Only used in reverse entries)
+		expiration	-- entry expiration (in ticks, where a tick is
+				   1024us, or ~ 1ms. Use 0 for an indefinite
+				   entry, default is 0)
+		sleepmode	-- RA's sleep mode (currently unused, default is
+				   0)
+		snr		-- SNR in the link to RA (currently unused,
+				   default is 0)
+
+	The command does not return anything.
+
+fwt_del
+	This command is used to remove an entry to the FWT table. The list of
+	parameters must follow the following structure:
+
+		iwpriv ethX fwt_del da ra [dir]
+
+	where the different parameters are:-
+		da		-- DA MAC address (in the form "00:11:22:33:44:55")
+		ra		-- RA MAC address (in the form "00:11:22:33:44:55")
+		dir		-- direction (1 for direct, 0 for reverse,
+				   default is 1)
+
+	The command does not return anything.
+
+fwt_lookup
+	This command is used to get the best route in the FWT table to a given
+	host. The only parameter is the MAC address of the host that is being
+	looked for.
+
+		iwpriv ethX fwt_lookup da
+
+	where:-
+		da		-- DA MAC address (in the form "00:11:22:33:44:55")
+
+	The command returns an output string identical to the one returned by
+	fwt_list described below.
+
+
+fwt_list
+	This command is used to list a route from the FWT table. The only
+	parameter is the index into the table. If you want to list all the
+	routes in a table, start with index=0, and keep listing until you get a
+	"(null)" string.  Note that the indicies may change as the fwt is
+	updated.  It is expected that most users will not use fwt_list directly,
+	but that a utility similar to the traditional route command will be used
+	to invoke fwt_list over and over.
+
+		iwpriv ethX fwt_list index
+
+	The output is a string of the following form:
+
+		da ra metric dir ssn dsn hopcount ttl expiration sleepmode snr
+
+	where the different fields are:-
+		da		-- DA MAC address (in the form "00:11:22:33:44:55")
+		ra		-- RA MAC address (in the form "00:11:22:33:44:55")
+		metric		-- route metric (cost: smaller-metric routes are preferred)
+		dir		-- direction (1 for direct, 0 for reverse)
+		ssn		-- Source Sequence Number (time at the RA for reverse routes)
+		dsn		-- Destination Sequence Number (time at the DA for direct routes)
+		hopcount	-- hop count (currently unused)
+		ttl		-- TTL (only used in reverse entries)
+		expiration	-- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
+		sleepmode	-- RA's sleep mode (currently unused)
+		snr		-- SNR in the link to RA (currently unused)
+
+fwt_list_route
+	This command is used to list a route from the FWT table. The only
+	parameter is the route ID. If you want to list all the routes in a
+	table, start with rid=0, and keep incrementing rid until you get a
+	"(null)" string. This function is similar to fwt_list. The only
+	difference is the output format.  Also note that this command is meant
+	for debugging.  It is expected that users will use fwt_lookup and
+	fwt_list.  One important reason for this is that the route id may change
+	as the route table is altered.
+
+		iwpriv ethX fwt_list_route rid
+
+	The output is a string of the following form:
+
+		da metric dir nid ssn dsn hopcount ttl expiration
+
+	where the different fields are:-
+		da		-- DA MAC address (in the form "00:11:22:33:44:55")
+		metric		-- route metric (cost: smaller-metric routes are preferred)
+		dir		-- direction (1 for direct, 0 for reverse)
+		nid		-- Next-hop (neighbor) host ID (nid)
+		ssn		-- Source Sequence Number (time at the RA for reverse routes)
+		dsn		-- Destination Sequence Number (time at the DA for direct routes)
+		hopcount	-- hop count (currently unused)
+		ttl		-- TTL count (only used in reverse entries)
+		expiration	-- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
+
+fwt_list_neigh
+	This command is used to list a neighbor from the FWT table. The only
+	parameter is the neighbor ID. If you want to list all the neighbors in a
+	table, start with nid=0, and keep incrementing nid until you get a
+	"(null)" string.  Note that the nid from a fwt_list_route command can be
+	used as an input to this command.  Also note that this command is meant
+	mostly for debugging.  It is expected that users will use fwt_lookup.
+	One important reason for this is that the neighbor id may change as the
+	neighbor table is altered.
+
+		iwpriv ethX fwt_list_neigh nid
+
+	The output is a string of the following form:
+
+		ra sleepmode snr references
+
+	where the different fields are:-
+		ra		-- RA MAC address (in the form "00:11:22:33:44:55")
+		sleepmode	-- RA's sleep mode (currently unused)
+		snr		-- SNR in the link to RA (currently unused)
+		references	-- RA's reference counter
+
+fwt_reset
+	This command is used to reset the FWT table, getting rid of all the
+	entries. There are no input parameters.
+
+		iwpriv ethX fwt_reset
+
+	The command does not return anything.
+
+fwt_cleanup
+	This command is used to perform user-based garbage recollection. The
+	FWT table is checked, and all the entries that are expired or invalid
+	are cleaned. Note that this is exported to the driver for debugging
+	purposes, as garbage collection is also fired by the firmware when in
+	space problems. There are no input parameters.
+
+		iwpriv ethX fwt_cleanup
+
+	The command does returns the number of invalid/expired routes deleted.
+
+fwt_time
+	This command returns a card's internal time representation.  It is this
+	time that is used to represent the expiration times of FWT entries.  The
+	number is not consistent from card to card; it is simply a timer count.
+	The fwt_time command is used to inspect the timer so that expiration
+	times reported by fwt_list can be properly interpreted.
+
+		iwpriv ethX fwt_time
+
+mesh_get_ttl
+
+	The mesh ttl is the number of hops a mesh packet can traverse before it
+	is dropped.  This parameter is used to prevent infinite loops in the
+	mesh network.  The value returned by this function is the ttl assigned
+	to all mesh packets.  Currently there is no way to control the ttl on a
+	per packet or per socket basis.
+
+	iwpriv ethX mesh_get_ttl
+
+mesh_set_ttl ttl
+
+	Set the ttl.  The argument must be between 0 and 255.
+
+	iwpriv ethX mesh_set_ttl <ttl>

+========================
+DEBUGFS COMMANDS
+========================
+
+those commands are used via debugfs interface
+
+===========
+rdmac
+rdbbp
+rdrf
+	These commands are used to read the MAC, BBP and RF registers from the
+	card.  These commands take one parameter that specifies the offset
+	location that is to be read.  This parameter must be specified in
+	hexadecimal (its possible to preceed preceding the number with a "0x").
+
+	Path: /debugfs/libertas_wireless/ethX/registers/
+
+	Usage:
+		echo "0xa123" > rdmac ; cat rdmac
+		echo "0xa123" > rdbbp ; cat rdbbp
+		echo "0xa123" > rdrf ; cat rdrf
+wrmac
+wrbbp
+wrrf
+	These commands are used to write the MAC, BBP and RF registers in the
+	card.  These commands take two parameters that specify the offset
+	location and the value that is to be written. This parameters must
+	be specified in hexadecimal (its possible to preceed the number
+	with a "0x").
+
+	Usage:
+		echo "0xa123 0xaa" > wrmac
+		echo "0xa123 0xaa" > wrbbp
+		echo "0xa123 0xaa" > wrrf
+
+sleepparams
+	This command is used to set the sleepclock configurations
+
+	Path: /debugfs/libertas_wireless/ethX/
+
+	Usage:
+		cat sleepparams: reads the current sleepclock configuration
+
+		echo "p1 p2 p3 p4 p5 p6" > sleepparams: writes the sleepclock configuration.
+
+		where:
+			p1 is Sleep clock error in ppm (0-65535)
+			p2 is Wakeup offset in usec (0-65535)
+			p3 is Clock stabilization time in usec (0-65535)
+			p4 is Control periodic calibration (0-2)
+			p5 is Control the use of external sleep clock (0-2)
+			p6 is reserved for debug (0-65535)
+
+subscribed_events
+
+	The subscribed_events directory contains the interface for the
+	subscribed events API.
+
+	Path: /debugfs/libertas_wireless/ethX/subscribed_events/
+
+	Each event is represented by a filename. Each filename consists of the
+	following three fields:
+	Value Frequency Subscribed
+
+	To read the current values for a given event, do:
+		cat event
+	To set the current values, do:
+		echo "60 2 1" > event
+
+	Frequency field specifies the reporting frequency for this event.
+	If it is set to 0, then the event is reported only once, and then
+	automatically unsubscribed. If it is set to 1, then the event is
+	reported every time it occurs. If it is set to N, then the event is
+	reported every Nth time it occurs.
+
+	beacon_missed
+	Value field specifies the number of consecutive missing beacons which
+	triggers the LINK_LOSS event. This event is generated only once after
+	which the firmware resets its state. At initialization, the LINK_LOSS
+	event is subscribed by default. The default value of MissedBeacons is
+	60.
+
+	failure_count
+	Value field specifies the consecutive failure count threshold which
+	triggers the generation of the MAX_FAIL event. Once this event is
+	generated, the consecutive failure count is reset to 0.
+	At initialization, the MAX_FAIL event is NOT subscribed by
+	default.
+
+	high_rssi
+	This event is generated when the average received RSSI in beacons goes
+	above a threshold, specified by Value.
+
+	low_rssi
+	This event is generated when the average received RSSI in beacons goes
+	below a threshold, specified by Value.
+
+	high_snr
+	This event is generated when the average received SNR in beacons goes
+	above a threshold, specified by Value.
+
+	low_snr
+	This event is generated when the average received SNR in beacons goes
+	below a threshold, specified by Value.
+
+extscan
+	This command is used to do a specific scan.
+
+	Path: /debugfs/libertas_wireless/ethX/
+
+	Usage: echo "SSID" > extscan
+
+	Example:
+		echo "LINKSYS-AP" > extscan
+
+	To see the results of use getscantable command.
+
+getscantable
+
+	Display the current contents of the driver scan table (ie. get the
+	scan results).
+
+	Path: /debugfs/libertas_wireless/ethX/
+
+	Usage:
+		cat getscantable
+
+setuserscan
+	Initiate a customized scan and retrieve the results
+
+
+	Path: /debugfs/libertas_wireless/ethX/
+
+    Usage:
+       echo "[ARGS]" > setuserscan
+
+         where [ARGS]:
+
+      chan=[chan#][band][mode] where band is [a,b,g] and mode is
+                               blank for active or 'p' for passive
+      bssid=xx:xx:xx:xx:xx:xx  specify a BSSID filter for the scan
+      ssid="[SSID]"            specify a SSID filter for the scan
+      keep=[0 or 1]            keep the previous scan results (1), discard (0)
+      dur=[scan time]          time to scan for each channel in milliseconds
+      probes=[#]               number of probe requests to send on each chan
+      type=[1,2,3]             BSS type: 1 (Infra), 2(Adhoc), 3(Any)
+
+    Any combination of the above arguments can be supplied on the command line.
+      If the chan token is absent, a full channel scan will be completed by
+      the driver.  If the dur or probes tokens are absent, the driver default
+      setting will be used.  The bssid and ssid fields, if blank,
+      will produce an unfiltered scan. The type field will default to 3 (Any)
+      and the keep field will default to 0 (Discard).
+
+    Examples:
+    1) Perform an active scan on channels 1, 6, and 11 in the 'g' band:
+            echo "chan=1g,6g,11g" > setuserscan
+
+    2) Perform a passive scan on channel 11 for 20 ms:
+            echo "chan=11gp dur=20" > setuserscan
+
+    3) Perform an active scan on channels 1, 6, and 11; and a passive scan on
+       channel 36 in the 'a' band:
+
+            echo "chan=1g,6g,11g,36ap" > setuserscan
+
+    4) Perform an active scan on channel 6 and 36 for a specific SSID:
+            echo "chan=6g,36a ssid="TestAP"" > setuserscan
+
+    5) Scan all available channels (B/G, A bands) for a specific BSSID, keep
+       the current scan table intact, update existing or append new scan data:
+            echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan
+
+    6) Scan channel 6, for all infrastructure networks, sending two probe
+       requests.  Keep the previous scan table intact. Update any duplicate
+       BSSID/SSID matches with the new scan data:
+            echo "chan=6g type=1 probes=2 keep=1" > setuserscan
+
+    All entries in the scan table (not just the new scan data when keep=1)
+    will be displayed upon completion by use of the getscantable ioctl.
