 12                 Intel 6000 Series Wi-Fi Adapters (6200AGN and 6300AGN)

 25           This driver uses the kernel's mac80211 subsystem.
 26 
 27           In order to use this driver, you will need a microcode (uCode)
 28           image for it. You can obtain the microcode from:
 29 
 30                   <http://intellinuxwireless.org/>.
 31 
 32           The microcode is typically installed in /lib/firmware. You can
 33           look in the hotplug script /etc/hotplug/firmware.agent to
 34           determine which directory FIRMWARE_DIR is set to when the script
 35           runs.
 36 
 37           If you want to compile the driver as a module ( = code which can be
 38           inserted in and removed from the running kernel whenever you want),
 39           say M here and read <file:Documentation/kbuild/modules.txt>.  The
 40           module will be called iwlwifi.

 55           This is the driver that supports the DVM firmware which is

 79           Say Y here to enable default bcast filtering configuration.
 80 
 81           Enabling broadcast filtering will drop any incoming wireless
 82           broadcast frames, except some very specific predefined
 83           patterns (e.g. incoming arp requests).
 84 
 85           If unsure, don't enable this option, as some programs might
 86           expect incoming broadcasts for their normal operations.

 92         bool "Enable full debugging output in the iwlwifi driver"
 93         depends on IWLWIFI
 94         ---help---
 95           This option will enable debug tracing output for the iwlwifi drivers
 96 
 97           This will result in the kernel module being ~100k larger.  You can
 98           control which debug output is sent to the kernel log by setting the
 99           value in
100 
101                 /sys/module/iwlwifi/parameters/debug
102 
103           This entry will only exist if this option is enabled.
104 
105           To set a value, simply echo an 8-byte hex value to the same file:
106 
107                   % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
108 
109           You can find the list of debug mask values in:
110                   drivers/net/wireless/iwlwifi/iwl-debug.h
111 
112           If this is your first time using this driver, you should say Y here
113           as the debug information can assist others in helping you resolve
114           any problems you may encounter.
115 
116 config IWLWIFI_DEBUGFS
117         bool "iwlwifi debugfs support"

119         ---help---
120           Enable creation of debugfs files for the iwlwifi drivers. This
121           is a low-impact option that allows getting insight into the
122           driver's state at runtime.
123 
124 config IWLWIFI_DEBUG_EXPERIMENTAL_UCODE
125         bool "Experimental uCode support"
126         depends on IWLWIFI && IWLWIFI_DEBUG
127         ---help---
128           Enable use of experimental ucode for testing and debugging.
129 
130 config IWLWIFI_DEVICE_TRACING
131         bool "iwlwifi device access tracing"
132         depends on IWLWIFI
133         depends on EVENT_TRACING
134         help
135           Say Y here to trace all commands, including TX frames and IO
136           accesses, sent to the device. If you say yes, iwlwifi will
137           register with the ftrace framework for event tracing and dump
138           all this information to the ringbuffer, you may need to
139           increase the ringbuffer size. See the ftrace documentation
140           for more information.
141 
142           When tracing is not enabled, this option still has some
143           (though rather small) overhead.
144 
145           If unsure, say Y so we can help you better when problems
146           occur.
