+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
+

+ routing protocol. The following commands are supported:
+
+ iwpriv ethX mesh_get_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>
+
+=========================
+ETHTOOL
+=========================
+
+
+Use the -i option to retrieve version information from the driver.
+
+# ethtool -i eth0
+driver: libertas
+version: COMM-USB8388-318.p4
+firmware-version: 5.110.7
+bus-info:
+
+Use the -e option to read the EEPROM contents of the card.
+
+ Usage:
+ ethtool -e ethX [raw on|off] [offset N] [length N]
+
+ -e retrieves and prints an EEPROM dump for the specified ethernet
+ device. When raw is enabled, then it dumps the raw EEPROM data
+ to stdout. The length and offset parameters allow dumping cer-
+ tain portions of the EEPROM. Default is to dump the entire EEP-
+ ROM.
+
+# ethtool -e eth0 offset 0 length 16
+Offset Values
+------ ------
+0x0000 38 33 30 58 00 00 34 f4 00 00 10 00 00 c4 17 00

+========================
+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.

+ * - Number of Probes to be sent
+ * - channel list
+ *
+ * If the SSID or BSSID filter is not present, disable/clear the filter.
+ * If the number of probes is not set, use the adapter default setting
+ * Qualify the channel
+ *
+ * @param priv A pointer to wlan_private structure
+ * @param puserscanin NULL or pointer to scan configuration parameters
+ * @param ppchantlvout Output parameter: Pointer to the start of the
+ * channel TLV portion of the output scan config
+ * @param pscanchanlist Output parameter: Pointer to the resulting channel
