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

 78         help
 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.

 90         depends on IWLMVM
 91         help
 92           Say Y here to enable U-APSD by default. This may cause
 93           interoperability problems with some APs, manifesting in lower than
 94           expected throughput due to those APs not enabling aggregation
 95 
 96           If unsure, say N.

101         bool "Enable full debugging output in the iwlwifi driver"
102         ---help---
103           This option will enable debug tracing output for the iwlwifi drivers
104 
105           This will result in the kernel module being ~100k larger.  You can
106           control which debug output is sent to the kernel log by setting the
107           value in
108 
109                 /sys/module/iwlwifi/parameters/debug
110 
111           This entry will only exist if this option is enabled.
112 
113           To set a value, simply echo an 8-byte hex value to the same file:
114 
115                   % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
116 
117           You can find the list of debug mask values in:
118                   drivers/net/wireless/iwlwifi/iwl-debug.h
119 
120           If this is your first time using this driver, you should say Y here
121           as the debug information can assist others in helping you resolve
122           any problems you may encounter.
123 
124 config IWLWIFI_DEBUGFS
125         bool "iwlwifi debugfs support"

127         ---help---
128           Enable creation of debugfs files for the iwlwifi drivers. This
129           is a low-impact option that allows getting insight into the
130           driver's state at runtime.
131 
132 config IWLWIFI_DEBUG_EXPERIMENTAL_UCODE
133         bool "Experimental uCode support"
134         depends on IWLWIFI_DEBUG

136           Enable use of experimental ucode for testing and debugging.
137 
138 config IWLWIFI_DEVICE_TRACING
139         bool "iwlwifi device access tracing"
140         depends on EVENT_TRACING
141         help
142           Say Y here to trace all commands, including TX frames and IO
143           accesses, sent to the device. If you say yes, iwlwifi will
144           register with the ftrace framework for event tracing and dump
145           all this information to the ringbuffer, you may need to
146           increase the ringbuffer size. See the ftrace documentation
147           for more information.
148 
149           When tracing is not enabled, this option still has some
150           (though rather small) overhead.
151 
152           If unsure, say Y so we can help you better when problems
153           occur.
