+=====================
+DRIVER LOADING
+=====================
+
+ o. Copy the firmware image (e.g. usb8388.bin) to /lib/firmware/
+
+ o. Load driver by using the following command:
+
+ insmod usb8388.ko [fw_name=usb8388.bin]
+
+=========================
+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 precede preceding the number with a "0x").
+
+ Path: /sys/kernel/debug/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 precede 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: /sys/kernel/debug/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: /sys/kernel/debug/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: /sys/kernel/debug/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: /sys/kernel/debug/libertas_wireless/ethX/
+
+ Usage:
+ cat getscantable
+
+setuserscan
+ Initiate a customized scan and retrieve the results
+
+
+ Path: /sys/kernel/debug/libertas_wireless/ethX/
+
+ Usage:
+ echo "[ARGS]" > setuserscan
+
+ where [ARGS]:
+
+ 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
+ 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 dur 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 a passive scan on all channels for 20 ms per channel:
+ echo "dur=20" > setuserscan
+
+ 2) Perform an active scan for a specific SSID:
+ echo "ssid="TestAP"" > setuserscan
+
+ 3) 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
+
+ 4) Scan for all infrastructure networks.
+ Keep the previous scan table intact. Update any duplicate BSSID/SSID
+ matches with the new scan data:
+ echo "type=1 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.
+
+hostsleep
+ This command is used to enable/disable host sleep.
+ Note: Host sleep parameters should be configured using
+ "ethtool -s ethX wol X" command before enabling host sleep.
+
+ Path: /sys/kernel/debug/libertas_wireless/ethX/
+
+ Usage:
+ cat hostsleep: reads the current hostsleep state
+ echo "1" > hostsleep : enable host sleep.
+ echo "0" > hostsleep : disable host sleep
