To compile this driver as a module, choose M here: the module will be
called ray_cs. If unsure, say N.

- ---help---
- A driver for the Intel PRO/Wireless 2100 Network
- Connection 802.11b wireless network adapter.
-
- See <file:Documentation/networking/README.ipw2100> for information on
- the capabilities currently enabled in this driver and for tips
- for debugging issues and problems.
-
- In order to use this driver, you will need a firmware image for it.
- You can obtain the firmware from
- <http://ipw2100.sf.net/>. Once you have the firmware image, you
- will need to place it in /lib/firmware.
-
- You will also very likely need the Wireless Tools in order to
- configure your card:
-
- <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
-
- It is recommended that you compile this driver as a module (M)
- rather than built-in (Y). This driver requires firmware at device
- initialization time, and when built-in this typically happens
- before the filesystem is accessible (hence firmware will be
- unavailable and initialization will fail). If you do choose to build
- this driver into your kernel image, you can avoid this problem by
- including the firmware and a firmware loader in an initramfs.
-
-config IPW2100_MONITOR
- bool "Enable promiscuous mode"
- depends on IPW2100
- ---help---
- Enables promiscuous/monitor mode support for the ipw2100 driver.
- With this feature compiled into the driver, you can switch to
- promiscuous mode via the Wireless Tool's Monitor mode. While in this
- mode, no packets can be sent.
-
-config IPW2100_DEBUG
- bool "Enable full debugging output in IPW2100 module."
- depends on IPW2100
- ---help---
- This option will enable debug tracing output for the IPW2100.
-
- This will result in the kernel module being ~60k larger. You can
- control which debug output is sent to the kernel log by setting the
- value in
-
- /sys/bus/pci/drivers/ipw2100/debug_level
-
- This entry will only exist if this option is enabled.
-
- If you are not trying to debug or develop the IPW2100 driver, you
- most likely want to say N here.

- ---help---
- A driver for the Intel PRO/Wireless 2200BG and 2915ABG Network
- Connection adapters.
-
- See <file:Documentation/networking/README.ipw2200> for
- information on the capabilities currently enabled in this
- driver and for tips for debugging issues and problems.
-
- In order to use this driver, you will need a firmware image for it.
- You can obtain the firmware from
- <http://ipw2200.sf.net/>. See the above referenced README.ipw2200
- for information on where to install the firmware images.
-
- You will also very likely need the Wireless Tools in order to
- configure your card:
-
- <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
-
- It is recommended that you compile this driver as a module (M)
- rather than built-in (Y). This driver requires firmware at device
- initialization time, and when built-in this typically happens
- before the filesystem is accessible (hence firmware will be
- unavailable and initialization will fail). If you do choose to build
- this driver into your kernel image, you can avoid this problem by
- including the firmware and a firmware loader in an initramfs.

-config IPW2200_MONITOR
- bool "Enable promiscuous mode"
- depends on IPW2200
- ---help---
- Enables promiscuous/monitor mode support for the ipw2200 driver.
- With this feature compiled into the driver, you can switch to
- promiscuous mode via the Wireless Tool's Monitor mode. While in this
- mode, no packets can be sent.
-
-config IPW2200_RADIOTAP
- bool "Enable radiotap format 802.11 raw packet support"
- depends on IPW2200_MONITOR
-
-config IPW2200_PROMISCUOUS
- bool "Enable creation of a RF radiotap promiscuous interface"
- depends on IPW2200_MONITOR
- select IPW2200_RADIOTAP
- ---help---
- Enables the creation of a second interface prefixed 'rtap'.
- This second interface will provide every received in radiotap
- format.
-
- This is useful for performing wireless network analysis while
- maintaining an active association.
-
- Example usage:
-
- % modprobe ipw2200 rtap_iface=1
- % ifconfig rtap0 up
- % tethereal -i rtap0
-
- If you do not specify 'rtap_iface=1' as a module parameter then
- the rtap interface will not be created and you will need to turn
- it on via sysfs:
-
- % echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
-
-config IPW2200_QOS
- bool "Enable QoS support"
- depends on IPW2200 && EXPERIMENTAL
-
-config IPW2200_DEBUG
- bool "Enable full debugging output in IPW2200 module."
- depends on IPW2200
- ---help---
- This option will enable low level debug tracing output for IPW2200.
-
- Note, normal debug code is already compiled in. This low level
- debug option enables debug on hot paths (e.g Tx, Rx, ISR) and
- will result in the kernel module being ~70 larger. Most users
- will typically not need this high verbosity debug information.
-
- If you are not sure, say N here.

+
+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts. The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames. With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.

+ * @ucode_api_max: Highest version of uCode API supported by driver.
+ * @ucode_api_min: Lowest version of uCode API supported by driver.
+ *
+ * We enable the driver to be backward compatible wrt API version. The
+ * driver specifies which APIs it supports (with @ucode_api_max being the
+ * highest and @ucode_api_min the lowest). Firmware will only be loaded if
+ * it has a supported API version. The firmware's API version will be
+ * stored in @iwl_priv, enabling the driver to make runtime changes based
+ * on firmware version used.
+ *
+ * For example,
+ * if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
+ * Driver interacts with Firmware API version >= 2.
+ * } else {
+ * Driver interacts with Firmware API version 1.
+ * }
+ *
+ * The ideal usage of this infrastructure is to treat a new ucode API
+ * release as a new hardware revision. That is, through utilizing the
+ * iwl_hcmd_utils_ops etc. we accommodate different command structures
+ * and flows between hardware versions (4965/5000) as well as their API
