iwlwifi: split the drivers for agn and legacy devices 3945/4965 



Intel WiFi devices 3945 and 4965 now have their own driver in the folder

	drivers/net/wireless/iwlegacy

Add support to build these drivers independently of the driver for
AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko,
and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko
contains code shared between both devices.

The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3
ABGN device.

config IWLWIFI_LEGACY_DEBUG

	bool "Enable full debugging output in 4965 and 3945 drivers"

	depends on IWLWIFI_LEGACY

	---help---

	  This option will enable debug tracing output for the iwlwifilegacy

	  drivers.



	  This will result in the kernel module being ~100k larger.  You can

	  control which debug output is sent to the kernel log by setting the

	  value in



		/sys/class/net/wlan0/device/debug_level



	  This entry will only exist if this option is enabled.



	  To set a value, simply echo an 8-byte hex value to the same file:



		  % echo 0x43fff > /sys/class/net/wlan0/device/debug_level



	  You can find the list of debug mask values in:

		  drivers/net/wireless/iwlwifilegacy/iwl-debug.h



	  If this is your first time using this driver, you should say Y here

	  as the debug information can assist others in helping you resolve

	  any problems you may encounter.



config IWLWIFI_LEGACY_DEBUGFS

        bool "4965 and 3945 debugfs support"

        depends on IWLWIFI_LEGACY && MAC80211_DEBUGFS

        ---help---

	  Enable creation of debugfs files for the iwlwifilegacy drivers. This

	  is a low-impact option that allows getting insight into the

	  driver's state at runtime.



config IWLWIFI_LEGACY_DEVICE_TRACING

	bool "iwlwifilegacy legacy device access tracing"

	depends on IWLWIFI_LEGACY

	depends on EVENT_TRACING

	help

	  Say Y here to trace all commands, including TX frames and IO

	  accesses, sent to the device. If you say yes, iwlwifilegacy will

	  register with the ftrace framework for event tracing and dump

	  all this information to the ringbuffer, you may need to

	  increase the ringbuffer size. See the ftrace documentation

	  for more information.



	  When tracing is not enabled, this option still has some

	  (though rather small) overhead.



	  If unsure, say Y so we can help you better when problems

	  occur.

	---help---

	  This option enables support for



	  Select to build the driver supporting the:



	  Intel Wireless WiFi Link 4965AGN



	  This driver uses the kernel's mac80211 subsystem.



	  In order to use this driver, you will need a microcode (uCode)

	  image for it. You can obtain the microcode from:



	          <http://intellinuxwireless.org/>.



	  The microcode is typically installed in /lib/firmware. You can

	  look in the hotplug script /etc/hotplug/firmware.agent to

	  determine which directory FIRMWARE_DIR is set to when the script

	  runs.



	  If you want to compile the driver as a module ( = code which can be

	  inserted in and removed from the running kernel whenever you want),

	  say M here and read <file:Documentation/kbuild/modules.txt>.  The

	  module will be called iwl4965.
