NOTE: In order to upgrade to 0.17 you must also upgrade your firmware to 2.1. You can download the firmware from http://ipw2200.sf.net/firmware.php.
If, when loading the module, you see an error in the kernel logs about conflicting firmware versions, then you do not have the correct firmware installed.
ISSUES: Ad-Hoc is currently not functional with 0.17. If you rely on Ad-Hoc capabilities, please do not use this version.

• Adjusted the behavior of ad-hoc to act much more like the ipw2100 does. This addresses several bugs relating to the formation/reformation of ad-hoc networks.
• Started initializing the ad-hoc station table when associating to an ad-hoc network. This fixes a problem that is at the root of may problem reports where network connectivity is lost in ad-hoc mode, yet both the driver and networking stack configuration is correct and the device is associated sending out beacons.
• Added noise statistic reporting for current association
• Fixed "associate" module parameter so that it works as the README states
• Fixed signal strength reporting.
• Added AP roaming support (via 802.11 re-association requests). If you have an ESS network that spans multiple APs and begin missing enough beacons from the currently associated AP, the driver will look for a better AP to associate with. If found, it will attempt to re-associate with that AP.
• Fixed code such that if a scan completes while disassociating, an association attempt is not made.
• Added dumping of Status and Config during fatal error dump (to help provide driver context during the fatal error)
• Changed missed beacons to report the % of missed beacons recently

• Merged ieee80211 double alloc into single allocation (thanks to Stephen Hemminger)
• Fixed compilation problem if CONFIG_IEEE80211_DEBUG is not defined (thanks to Stephen Hemminger and Luc Saillard)
• Really fixed bug #271 so we properly compare essids when looking for a valid network to connect to
• Fixed bug #402 so that WEP can be used with ad-hoc mode
• Fixed bug #414 problem with SSIDs being scrambled when hidden networks detected (also resulted in multiple hidden networks showing in scan results)
• Fixed bug #425/285 problem with 802.11b networks being extremely slow
• Added support for multi-mode access points. Fixes bugs like #397 where the driver is not able to associate with an ap in 'b' mode even though the ap provides both 'b' and 'g' bands
• Fixed bug #421 problem with a panic if fragmentation is used. NOTE: Fragmentation itself is currently broken (nothing goes through) but it won't panic anymore.
• Fixed bug #237 so that link quality is now temporal and should adjust dynamically as the network quality changes (previously it would slowly stagnate onto a fixed level)

• Fixed #399 - max fragmentation threshold was 2342 instead of 2346
• Fixed problem with link state no longer being detected by ethtool
• Initialize atim_window in network during scans (fixes problem with adhoc networks)

• Test fix for bug #207 by changing how a network is determined to be unique. Previously, only the BSSID was checked to determine if a new probe or beacon was for an already discovered network. Now the BSSID, ESSID, and channel must match for the network to be considered the same.
• Fixed bug #265 by adding a filter for removing our own recieved packets since the firmware does not do this for us.
• Fixed bug #269 so that ad-hoc will come up correctly the first time when preemption is enabled.
• Fixed bug #270 which was fatal errors triggered by multiple association commands on top of each other.
• Fixed bug #271 so that we correctly match essids when the assigned essid is a substring of a network essid
• Fixed bug #275 which kept the driver from being able to use a default crypto key other than the first or second key.
• Fixed bug #277 which caused the setting of the active key, or specifying a key, to corrupt the key being assigned.
• Fixed bug #344 - wireless stats are now provided even if the HW is down or not associated with a network.
• Fixed bug #365 which would result in kernel stack dumps in the system log file due to an improper scheduling call while in atomic mode.
• Fixed bug #378 which would cause an endless loop of scans if a scan was triggered with an "iwlist ethX scan" while associated.
• Fixed #393 such that only unicast frames request an ACK
• Fixed bug #404 so that we correctly fail when the wrong firmware version is loaded.
• Synchornized ieee80211 module with ipw2100 v1.0.1 (modifed ieee80211 initialization, and Tx data path)
• Moved the trans_start reset to that the TX watchdog can actually fire if the HW stalls out.

• Modified SW/HW rf_kill interaction functionality. See README.ipw2200 for details on current usage.
• Fixed #239: iwconfig eth1 rts off/auto not supported
• Fixed problem with not being able to associate with non-broadcast ESSID APs
• Changed default temporal timeout for scan age to 15s
• Changed MAC2STR and MACSTR to MAC_FMT and MAC_ARG
• Fixed problem with scan results not expiring
• Fixed a bug in ad-hoc support (#295) that prevented the creation of a new ad-hoc network
• Reduced interval of scan requests to 1/10th second (vs. 5 seconds)
• Modified scan logic to alternate between directed and active scanning when an ESSID is defined. This should improve AP to AP roaming via ESSID selection.
• Increased dwell time on directed scans to 100ms from 20ms
• Fixed fragmentation for both wep and with no encryption
• Fixed wireless stats reporting to indicate that the noise level is invalid. This version of the firmware does not provide noise statistics.
• Fixed a bug that prevented 'iwpriv ethX set_mode N' from working correctly

• Changed alloc_skb to use GFP_ATOMIC vs. GFP_ATOMIC| GFP_DMA (thanks to Roland Dreier) GFP_ATOMIC needs to be used as GFP_KERNEL may block, and the call is made from the default work queue during adapter load
• Fixed problem with module_param not building on some systems (thanks to Pieter Hollants and Sebastian Henrich)
• Added additional debug output during association to indicate security parameters (to assist in connection debugging)
• Misc cleanups (thanks to Stephen Hemminger)
  • Un 'inline' initialization functions
  • Added const to a few locations

• Hooked up the ability to set the fragmentation threshold. Unfortunately, once set you won't receive any packets.
• Fixed problem with privacy capability not being compared correctly when assessing viability of a network for association.
• Added debug level output into ieee80211* modules. You can access the debug levels via the debug module parameter as well as through /proc/net/ieee80211/debug_level, and see values via the idvals script
• Corrected support of 'iwlist ${IFNAME} bitrate'
• Corrected support of 'iwlist ${IFNAME} power'
• Added support for setting the TX power via 'iwconfig ${IFNAME} txpower ${LEVEL}'.
• Added support for setting the fragmentation threshold via 'iwconfig ${IFNAME} frag ${THRESHOLD}'.
• Added PSP power management support (thanks to An-Cheng Huang)
• Added support for suspend / resume.
• Fixed problem with setting an ESSID to a network that doesn't exist in Managed mode would result in the creation of an AdHoc network.
• Changed the way modulation and freq_band are stored and accessed.

• Fixed problem with manual disabling of RF via rf_kill sysfs entry wasn't resulting in the card actually being disabled.
• Added mode module parameter so you can start the device in either Managed or AdHoc mode (see README.ipw2200 for more information)
• Modified logic for detecting hidden SSIDs to work with how Linksys APs do it.
• Hooked in the rest of AdHoc code. You can now create adhoc networks, associate to existing ones, etc.
• Added adhoc_create module parameter for configuring the driver to auto create a network if you have provided the channel and network name.
• More changes to the scan logic, adding more debug output to indicate why specific networks are chosen over others (enable those messages by turning on the SCAN debug level. See `dvals` for the specific value.)
• Added a printk() to the pci probe indicating if it detects a 2915ABG or 2200BG adapter.
• Fixed problem with setting IW_MODE to AUTO (previously it just didn't work -- now it defaults back to IW_MODE_INFRA)
• Fixed problem with device coming up even if manual disable specified.
• Fixed problem with udev (or anything else that parsed all sysfs entries) with causing error log storms to the kernel log.

• Fixed support for all 802.11G extended rates
• Ad-Hoc code starting to show up. You can now create Ad-Hoc networks and join with other cells. Data Tx/Rx is still in the works.
• Added mode switching support to WX:

  	% iwconfig eth1 mode (managed|ad-hoc)

• Enhanced the iwlist scan results to (hopefully) be more clear on various statistics.
• Added support for restricting the 802.11 mode via a iwpriv method. See README.ipw2200 for more information.
• Fixed UNKNOWNSTATUS_ERROR if AdHoc beacon received while in managed mode (thanks to Yi Zhu)
• Fixed UNKNOWNSTATUS_ERROR if RF kill enabled when loading driver (thanks to Yi Zhu)
• Reworked IE parser to use an iterative loop, based on Pedro Ramalhais' original WPA port (thanks to Liang Chai)
• Fixed stricter type checking errors (thanks to Pedro Ramalhais)
• Fix oops in ieee80211_crypt_free (thanks to Yi Zhu)
• Fixed module reference counting of ieee modules (thanks to Stephen Hemminger)
• Fixed oops if CONFIG_NETLINK enabled (thanks to Yi Zhu)
• Misc. code cleanups (extra casts removed, unused function warning) (thanks to Scott Feldman)
• Changed AP detection logic so that it only considers a probe response to be a duplicate if both the BSSID and ESSID match (allowing a single BSSID to broadcast multiple ESSIDs)
• Modified load sequence such that if the RF switch is disabled during load it doesn't try and bring up the network.
• Modified dev->open so that it doesn't start the queue unless it is associated
• Sync'd ipw2100's ieee80211 module changes

• Fixed rate reporting to start with reporting maximum supported data rate, then falling back after enough packets have Tx'd to be able to accurately determine the true data rate.
• Added a space after __FUNCTION__ to remove compilation problems experienced by some (thanks to Andreas Ruess)
• Added support for associating with 802.11a APs (thanks to Liang Chai)
• Improved quality/signal level reporting (thanks to An-Cheng Huang)
• Misc. code cleanups (thanks to Stephen Hemminger):
  • Change to use sysfs attribute groups
  • Fix to incremement Tx packets
  • Removal of IRQ save in the ISR
  • Removed redundant STATUS_DEV_OPEN
  • Changed vmalloc -> kmalloc
  • Several global -> static variable change
  • Use C99 intializars in iw_handler declarations
• Modified the Makefile to define the CONFIG_IEEE80211_CRYPT_*differently
• Modified the AP selection logic to pick the AP with the strongest signal that meets the other configured criteria.
• Modified AP selection logic to discard APs whose scan age has expired.
• Added code to set the sensitivity in the firmware upon association.
• Added code to correctly seed the random number control in the firmware.
• Added code to try and correct the intermittent failure seen sometimes while loading the driver.
• Added code to detect when enough beacons have been missed to trigger a disassociation, and to then invoke the disassociation.

• Fixed Makefile problem with compiling WEP support (thanks to Yi Zhu)
• Fixed support for associating with G-only APs (and also supporting all of the G/B-rates in Mixed mode)
• Modified iwconfig output to report either 'unassociated' or 'ieee 802.11{band}' where band is one of a, b, or g.
• Fixed error preventing modprobe from consistently working (thanks to Yi Zhu)

NOTE: In order to upgrade to 0.6 you must also upgrade your firmware to 2.0. You can download the firmware from http://ipw2200.sf.net/firmware.php. If, when loading the module, you see an error in the kernel logs about conflicting firmware versions (2 != 1) or (1 != 2) then you do not have the correct firmware installed.

• Updated firmware interface to support new extended scan.
• Added ABG PCI ids
• Added support for G data rates.
• Partial support for A data rates.
• Fixed ordinal setup/reading code so that real values can be reported through wireless statistics.
• Partial change for reporting link quality through iwconfig -- not completed.
• Refactored IPW_BAND_* to IPW_IEEE_* to try and use better terminology when referencing 802.11 modes (a,b,g) vs. frequency bands (2.4Ghz,5.2Ghz)
• Misc. code cleanup (thanks to Stephen Hemminger):
  • If error log is empty, don't print the header
  • Removed ipw_net_change_mtu since alloc_etherdev will set it to eth_change_mtu which enforces the same restrictions.
  • Variables changed to private that are only used in ipw2200_main
  • Removed forward inline declaration, it really doesn't matter
  • Chagned snprint stuff not inline (it can't be performance sensitive), and data doesn't get modified (const).

• Fixed problem with load retry logic re-allocating Rx buffers repeatedly (skb leak)
• Fixed SWSUSP compilation dependency to CONFIG_SOFTWARE_SUSPEND2
• Fixed oops if sysfs entries were read after the driver fails to load if the firmware is missing.
• Moved probe / beacon handling into ieee module (shared with ipw2100)
• Changed to use netdev_priv consistently (thanks to Stephen Hemminger)
• Fix the initialization code (thanks to Stephen Hemminger):
  • memset is unnecessary since alloc_etherdev does it already
  • SET_NETDEV_DEV so that /sys/class/net/eth0/device symlink is created
  • don't set name to "eth%d" already done by alloc_etherdev
  • don't mask register_netdev error codes
• Misc. code cleanup (thanks to Stephen Hemminger):
  • get rid of left over cruft in ipw2200 priv stuff that is set but never used
  • debug/channel should be local variables (global namespace conflicts possible).
  • extra semi-colon in IPW_DEBUG is bug waiting to happen.
• Report firmware version via ethtool (like other drivers) rather than special sysfs hook. (thanks to Stephen Hemminger)
• Fixed TCP session freezing problem (thanks to Yi Zhu)
• Added support for non-broadcasting ESSIDs (thanks to Andreas Oberritter)

The following is the email announcement to the LKML:

To: linux-kernel@vger.kernel.org, netdev@oss.sgi.com Subject: [Announce] Update on ipw2100, ipw2200, and support for Intel PRO/Wireless 2915ABG It's been a while since I've updated lkml and netdev on the progress of the ipw projects. Given the recent announcement by Intel for the introduction of Intel PRO/Wireless 2915 ABG Network Connection miniPCI adapter, I thought now was a good time... First, thanks to everyone that has been contributing, using, testing, and reporting feedback for the projects described below. The support by folks in the community has been terrific -- the drivers wouldn't be anywhere near as feature rich and stable as they are today if not for the contributions of everyone. The ipw2100 project (802.11b) has progressed very well. We are in the process of cleaning up the driver for submittal to netdev for eventual inclusion into the kernel. The driver currently supports wep, 802.1x, monitor mode, adhoc, infrastructure, etc. Suspend/resume isn't quite functioning yet, but we'll get there soon. This project is hosted at http://ipw2100.sf.net. The ipw2200 project (802.11bg), which was launched back in May, is quickly catching up to the ipw2100 project in terms of functionality. It currently supports wep and 802.1x in infrastructure mode. Currently it will only associate at B data rates; hooking in the G capabilities is going on right now. We'll then tackle adhoc and remaining feature gaps. We had been planning on holding off submittal for kernel inclusion until we were feature complete. However, several folks have requested that we accelerate that plan and get it in sooner rather than later. To that end we're working to try and get it ready for submittal along with the ipw2100 project. This project is hosted at http://ipw2200.sf.net. The ipw2100 and ipw2200 projects currently share the 802.11 frame handling stack for Tx/Rx and some management frame processing. That code has been pulled into its own module suite (ieee80211), based on work from the Host AP project. That code needs to be resync'd with the Host AP code (and vice versa where appropriate) so that then all of those drivers will be able to leverage a single wireless network stack. Anyway, this brings me to announcing Linux support for the Intel PRO/Wireless 2915 ABG Network Connection adapter. As of next week, the ipw2200 project will also begin supporting the ABG adapter. From the driver's perspective, the only change between the two cards is the addition fo the A radio on the 2915. So, adding support for the ABG is just a matter of updating the firmware used by the ipw2200 project, adding PCI id's, and putting in support for A. That work will progress as we continue to bring full support for the ipw2200 project. At some point in the near future we will rename the ipw2200 project to something more appropriate to identify it as supporting both the 2200 and 2915 adapters. Thanks, James

• Hooked in WEP. You can now use encrypted sessions. 802.1x should also work (802.1x hasn't been tested). Only supports OPEN authentication.
• RF Kill switch is now supported. Manual driver based RF kill support added through sysfs entry (see README.ipw2200)
• Fixed scan results to report channel # for APs vs frequeny
• Added privacy capability matching to association selection -- the driver will no longer associate with APs that have different privacy capabilities enabled than the station
• Switched the IPW_DEBUG_ERROR and WARNING macros to always use printk so that release builds, and users without a debug mask set will still see error conditions in the kernel log.
• Added RTS threshold WE handler
• Added compilation support for having the SWSUSP patch installed (thanks to Morten Nilsen)
• Modified net_dev declaration to compile on 2.4.27 (thanks to Yi Zhu)

• Implementation of many WE commands (still a lot to go)
• Scanning and association are working.
• Tx/Rx functioning for non-WEP enabled sessions
• Lots and lots of code changes
• ieee80211 pulled in from ipw2100 project.

• firmware loading
• skeleton wireless extensions
• eeprom access
• new sysfs tweakables
• skeleton for RX and TX queues

• Initial public release
• Fixed proc oops on module load
• Removed compilation warnings
• Added full list of device IDs

Intel has officially launched this project as of today. As a result, we are now free to engage in more technical discussions on our implementation plan for the IPW2200. A primary goal of this project, in addition to providing the features Linux users care about, is to build a unified driver framework for both the IPW2100 and IPW2200.

If you are curious about our ideas in this area, and have any ideas of your own or would like to contribute in any way, please join the mailing list and send out your thoughts and questions.

You can join the mailing list here. NOTE: To help reach the goal of a unified driver, both the IPW2100 and IPW2200 projects are set up to use the same mailing list. If it becomes evident that we need to create a mailing list specifically for the development of the IPW2200 driver we will do so.

The following is the email announcement to the LKML:

To: linux-kernel@vger.kernel.org Subject: [Announce] Intel PRO/Wireless 2200BG 802.11b/g Project Intel is pleased to announce the launch of an open source project to support the Intel PRO/Wireless 2200BG Network Connection miniPCI adapter (IPW2200). The project site is up and in the coming weeks you can expect initial source to become available providing the foundation for supporting this hardware. We are announcing to the LKML now as we value working with the Linux community and wanted to let you know directly that Intel has now officially started this project. The project is hosted at http://ipw2200.sourceforge.net. A development mailing list is available (linked from the top of the IPW2200 project page) so if you are interested in this project, go subscribe to the mailing list and/or set yourself up to monitor the file releases. Please let me know if you have any questions. Thanks, James
