44Use the -e option to read the EEPROM contents of the card.
45
46 Usage:
47 ethtool -e ethX [raw on|off] [offset N] [length N]
48
49 -e retrieves and prints an EEPROM dump for the specified ethernet
50 device. When raw is enabled, then it dumps the raw EEPROM data
51 to stdout. The length and offset parameters allow dumping cer-
52 tain portions of the EEPROM. Default is to dump the entire EEP-
53 ROM.

61DEBUGFS COMMANDS
62========================
63
64those commands are used via debugfs interface
65
66===========
67rdmac
68rdbbp
69rdrf
70 These commands are used to read the MAC, BBP and RF registers from the
71 card. These commands take one parameter that specifies the offset
72 location that is to be read. This parameter must be specified in
73 hexadecimal (its possible to precede preceding the number with a "0x").
74
75 Path: /sys/kernel/debug/libertas_wireless/ethX/registers/
76
77 Usage:
78 echo "0xa123" > rdmac ; cat rdmac
79 echo "0xa123" > rdbbp ; cat rdbbp
80 echo "0xa123" > rdrf ; cat rdrf
81wrmac
82wrbbp
83wrrf
84 These commands are used to write the MAC, BBP and RF registers in the
85 card. These commands take two parameters that specify the offset
86 location and the value that is to be written. This parameters must
87 be specified in hexadecimal (its possible to precede the number
88 with a "0x").
89
90 Usage:
91 echo "0xa123 0xaa" > wrmac
92 echo "0xa123 0xaa" > wrbbp
93 echo "0xa123 0xaa" > wrrf
94
95sleepparams
96 This command is used to set the sleepclock configurations
97
98 Path: /sys/kernel/debug/libertas_wireless/ethX/
99
100 Usage:
101 cat sleepparams: reads the current sleepclock configuration
102
103 echo "p1 p2 p3 p4 p5 p6" > sleepparams: writes the sleepclock configuration.
104
105 where:
106 p1 is Sleep clock error in ppm (0-65535)
107 p2 is Wakeup offset in usec (0-65535)
108 p3 is Clock stabilization time in usec (0-65535)
109 p4 is Control periodic calibration (0-2)
110 p5 is Control the use of external sleep clock (0-2)
111 p6 is reserved for debug (0-65535)
112
113subscribed_events
114
115 The subscribed_events directory contains the interface for the
116 subscribed events API.
117
118 Path: /sys/kernel/debug/libertas_wireless/ethX/subscribed_events/
119
120 Each event is represented by a filename. Each filename consists of the
121 following three fields:
122 Value Frequency Subscribed
123
124 To read the current values for a given event, do:
125 cat event
126 To set the current values, do:
127 echo "60 2 1" > event
128
129 Frequency field specifies the reporting frequency for this event.
130 If it is set to 0, then the event is reported only once, and then
131 automatically unsubscribed. If it is set to 1, then the event is
132 reported every time it occurs. If it is set to N, then the event is
133 reported every Nth time it occurs.
134
135 beacon_missed
136 Value field specifies the number of consecutive missing beacons which
137 triggers the LINK_LOSS event. This event is generated only once after
138 which the firmware resets its state. At initialization, the LINK_LOSS
139 event is subscribed by default. The default value of MissedBeacons is
140 60.
141
142 failure_count
143 Value field specifies the consecutive failure count threshold which
144 triggers the generation of the MAX_FAIL event. Once this event is
145 generated, the consecutive failure count is reset to 0.
146 At initialization, the MAX_FAIL event is NOT subscribed by
147 default.
148
149 high_rssi
150 This event is generated when the average received RSSI in beacons goes
151 above a threshold, specified by Value.
152
153 low_rssi
154 This event is generated when the average received RSSI in beacons goes
155 below a threshold, specified by Value.
156
157 high_snr
158 This event is generated when the average received SNR in beacons goes
159 above a threshold, specified by Value.
160
161 low_snr
162 This event is generated when the average received SNR in beacons goes
163 below a threshold, specified by Value.
164

180 scan results).
181
182 Path: /sys/kernel/debug/libertas_wireless/ethX/
183
184 Usage:
185 cat getscantable
186
187setuserscan
188 Initiate a customized scan and retrieve the results
189
190
191 Path: /sys/kernel/debug/libertas_wireless/ethX/
192
193 Usage:
194 echo "[ARGS]" > setuserscan
195
196 where [ARGS]:
197
198 bssid=xx:xx:xx:xx:xx:xx specify a BSSID filter for the scan
199 ssid="[SSID]" specify a SSID filter for the scan
200 keep=[0 or 1] keep the previous scan results (1), discard (0)
201 dur=[scan time] time to scan for each channel in milliseconds
202 type=[1,2,3] BSS type: 1 (Infra), 2(Adhoc), 3(Any)
203
204 Any combination of the above arguments can be supplied on the command
205 line. If dur tokens are absent, the driver default setting will be used.
206 The bssid and ssid fields, if blank, will produce an unfiltered scan.
207 The type field will default to 3 (Any) and the keep field will default
208 to 0 (Discard).
209
210 Examples:
211 1) Perform a passive scan on all channels for 20 ms per channel:
212 echo "dur=20" > setuserscan
213
214 2) Perform an active scan for a specific SSID:
215 echo "ssid="TestAP"" > setuserscan
216
217 3) Scan all available channels (B/G, A bands) for a specific BSSID, keep
218 the current scan table intact, update existing or append new scan data:
219 echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan
220
221 4) Scan for all infrastructure networks.
222 Keep the previous scan table intact. Update any duplicate BSSID/SSID
223 matches with the new scan data:
224 echo "type=1 keep=1" > setuserscan
225
226 All entries in the scan table (not just the new scan data when keep=1)
227 will be displayed upon completion by use of the getscantable ioctl.
228
229hostsleep
230 This command is used to enable/disable host sleep.
231 Note: Host sleep parameters should be configured using
232 "ethtool -s ethX wol X" command before enabling host sleep.
233
234 Path: /sys/kernel/debug/libertas_wireless/ethX/
235
236 Usage:
237 cat hostsleep: reads the current hostsleep state
238 echo "1" > hostsleep : enable host sleep.
239 echo "0" > hostsleep : disable host sleep
240
241========================
242IWCONFIG COMMANDS
243========================
244power period
245
246 This command is used to configure the station in deep sleep mode /
247 auto deep sleep mode.
248
249 The timer is implemented to monitor the activities (command, event,
250 etc.). When an activity is detected station will exit from deep
251 sleep mode automatically and restart the timer. At timer expiry
252 (no activity for defined time period) the deep sleep mode is entered
253 automatically.
254
255 Note: this command is for SDIO interface only.
256
257 Usage:
258 To enable deep sleep mode do:
259 iwconfig wlan0 power period 0
260 To enable auto deep sleep mode with idle time period 5 seconds do:
261 iwconfig wlan0 power period 5
262 To disable deep sleep/auto deep sleep mode do:
263 iwconfig wlan0 power period -1
