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

 82         help
 83           Say Y here to enable default bcast filtering configuration.
 84 
 85           Enabling broadcast filtering will drop any incoming wireless
 86           broadcast frames, except some very specific predefined
 87           patterns (e.g. incoming arp requests).
 88 
 89           If unsure, don't enable this option, as some programs might
 90           expect incoming broadcasts for their normal operations.

 94         depends on IWLMVM
 95         help
 96           Say Y here to enable U-APSD by default. This may cause
 97           interoperability problems with some APs, manifesting in lower than
 98           expected throughput due to those APs not enabling aggregation
 99

104 config IWLWIFI_DEBUG
105         bool "Enable full debugging output in the iwlwifi driver"
106         ---help---
107           This option will enable debug tracing output for the iwlwifi drivers
108 
109           This will result in the kernel module being ~100k larger.  You can
110           control which debug output is sent to the kernel log by setting the
111           value in
112 
113                 /sys/module/iwlwifi/parameters/debug
114 
115           This entry will only exist if this option is enabled.
116 
117           To set a value, simply echo an 8-byte hex value to the same file:
118 
119                   % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
120 
121           You can find the list of debug mask values in:
122                   drivers/net/wireless/iwlwifi/iwl-debug.h
123 
124           If this is your first time using this driver, you should say Y here
125           as the debug information can assist others in helping you resolve
126           any problems you may encounter.
127 
128 config IWLWIFI_DEBUGFS
129         bool "iwlwifi debugfs support"

131         ---help---
132           Enable creation of debugfs files for the iwlwifi drivers. This
133           is a low-impact option that allows getting insight into the
134           driver's state at runtime.
135 
136 config IWLWIFI_DEBUG_EXPERIMENTAL_UCODE
137         bool "Experimental uCode support"
138         depends on IWLWIFI_DEBUG
139         ---help---
140           Enable use of experimental ucode for testing and debugging.
141 
142 config IWLWIFI_DEVICE_TRACING
143         bool "iwlwifi device access tracing"
144         depends on EVENT_TRACING
145         default y
146         help
147           Say Y here to trace all commands, including TX frames and IO
148           accesses, sent to the device. If you say yes, iwlwifi will
149           register with the ftrace framework for event tracing and dump
150           all this information to the ringbuffer, you may need to
151           increase the ringbuffer size. See the ftrace documentation
152           for more information.
153 
154           When tracing is not enabled, this option still has some
155           (though rather small) overhead.
156 
157           If unsure, say Y so we can help you better when problems
158           occur.
