+3. Sysfs Helper Files
+---------------------------
-To determine if you have such a switch, you can check the contents of:
+There are several ways to control the behavior of the driver. Many of the
+general capabilities are exposed through the Wireless Tools (iwconfig). There
+are a few capabilities that are exposed through entries in the Linux Sysfs.
- /sys/bus/pci/drivers/ipw2100/*/rf_kill
-A value of:
+----- Driver Level ------
+For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
+
+ debug_level
- Radio is {en,dis}abled by RF switch
+ This controls the same global as the 'debug' module parameter. For
+ information on the various debugging levels available, run the 'dvals'
+ script found in the driver source directory.
-means that you have an RF switch and the radio is in the state
-described.
+ NOTE: 'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
+ on.
-A value of:
+----- Device Level ------
+For the device level files look in
+
+ /sys/bus/pci/drivers/ipw2100/{PCI-ID}/
- Your hardware does not have an RF switch
+For example:
+ /sys/bus/pci/drivers/ipw2100/0000:02:01.0
-is self explanatory. In this case you should not need to worry about
-enabling the radio.
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
+ rf_kill
+ read -
+ 0 = RF kill not enabled (radio on)
+ 1 = SW based RF kill active (radio off)
+ 2 = HW based RF kill active (radio off)
+ 3 = Both HW and SW RF kill active (radio off)
+ write -
+ 0 = If SW based RF kill active, turn the radio back on
+ 1 = If radio is on, activate SW based RF kill
+
+ NOTE: If you enable the SW based RF kill and then toggle the HW
+ based RF kill from ON -> OFF -> ON, the radio will NOT come back on
