+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>

+
+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.
+

+
+fwt_del
+       This command is used to remove an entry to the FWT table. The list of

+
+               iwpriv ethX fwt_del da ra [dir]
+
+       where the different parameters are:-

+       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.

+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.

+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.
+

+       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

+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:

+
+       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

+       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.
