| 27 | This driver uses the kernel's mac80211 subsystem. |
| 28 | |
| 29 | In order to use this driver, you will need a firmware |
| 30 | image for it. You can obtain the microcode from: |
| 31 | |
| 32 | <http://wireless.kernel.org/en/users/Drivers/iwlwifi>. |
| 33 | |
| 34 | The firmware is typically installed in /lib/firmware. You can |
| 35 | look in the hotplug script /etc/hotplug/firmware.agent to |
| 36 | determine which directory FIRMWARE_DIR is set to when the script |
| 37 | runs. |
| 38 | |
| 39 | If you want to compile the driver as a module ( = code which can be |
| 40 | inserted in and removed from the running kernel whenever you want), |
| 41 | say M here and read <file:Documentation/kbuild/modules.txt>. The |
| 42 | module will be called iwlwifi. |

| 84 | Enabling broadcast filtering will drop any incoming wireless |
| 85 | broadcast frames, except some very specific predefined |
| 86 | patterns (e.g. incoming arp requests). |
| 87 | |

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

| 144 | help |
| 145 | Say Y here to trace all commands, including TX frames and IO |
| 146 | accesses, sent to the device. If you say yes, iwlwifi will |
| 147 | register with the ftrace framework for event tracing and dump |
| 148 | all this information to the ringbuffer, you may need to |
| 149 | increase the ringbuffer size. See the ftrace documentation |
| 150 | for more information. |
| 151 | |
| 152 | When tracing is not enabled, this option still has some |
| 153 | (though rather small) overhead. |
