+
+=====================
+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
+------          ------

+========================
+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]:
+
+      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.
