It supports both wireless extensions and CFG80211, but I could not tell if it requires using both. This device used to be one of the most common ones 20 years ago, but has been orphaned for most of the time since then, and the conversion to cfg80211 has stalled in 2010.

Keep in mind that the PCMCIA - * spec specifies the CIS as the lower 8 bits of each word read from - * the CIS, so to read the bytes of the CIS, read every other byte - * (0,2,4,...). Passing that test, you need to enable the I/O address - * space on the PCMCIA card via the PCMCIA COR register. This is the - * first byte following the CIS. In my case (which may not have any - * relation to what's on the PRISM2 cards), COR was at offset 0x800 - * within the PCI memory space. Write 0x41 to the COR register to - * enable I/O mode and to select level triggered interrupts. To - * confirm you actually succeeded, read the COR register back and make - * sure it actually got set to 0x41, in case you have an unexpected - * card inserted. - * - * Following that, you can treat the second PCI I/O address space (the - * one that's not 0x80 in length) as the PCMCIA I/O space. - * - * Note that in the Eumitcom's source for their drivers, they register - * the interrupt as edge triggered when registering it with the - * Windows kernel. I don't recall how to register edge triggered on - * Linux (if it can be done at all). But in some experimentation, I - * don't see much operational difference between using either - * interrupt mode. Don't mess with the interrupt mode in the COR - * register though, as the PLX9052 wants level triggers with the way - * the serial EEPROM configures it on the WL11000. - * - * There's some other little quirks related to timing that I bumped - * into, but I don't recall right now. Also, there's two variants of - * the WL11000 I've seen, revision A1 and T2. These seem to differ - * slightly in the timings configured in the wait-state generator in - * the PLX9052. There have also been some comments from Eumitcom that - * cards shouldn't be hot swapped, apparently due to risk of cooking - * the PLX9052. I'm unsure why they believe this, as I can't see - * anything in the design that would really cause a problem, except - * for crashing drivers not written to expect it. And having developed - * drivers for the WL11000, I'd say it's quite tricky to write code - * that will successfully deal with a hot unplug. Very odd things - * happen on the I/O side of things. But anyway, be warned.

The driver has been orphaned since 2010 and only seen cosmetic updates long before than. Jean Tourrilhes pointed out in a 2005 changelog that he tested a change on actual hardware, which was apparently already noteworthy back then.

Also, some packet types are never -sent up by the card, so you will never see them (ack, rts, cts, probe -etc.) There is a simple program (showcap) included in the ray_cs -package which parses the 802.11 headers. - -Known Problems and missing features - - Does not work with non x86 - - Does not work with SMP - - Support for defragmenting frames is not yet debugged, and in - fact is known to not work.

This makes it more modern than any of the others, but Kalle already classified it as "legacy" in commit 298e50ad8eb8f ("wifi: move raycs, wl3501 and rndis_wlan to legacy directory"). Jussi Kivilinna worked on this driver between 2008 and 2012, and it has only seen cosmetic updates after that.

Unlike the other drivers that are suggested for removal, this one is still officially maintained. According to Johannes Berg, there was an effort to finish the move away from wext in the past, but the last evidence of this that I could find is from commit a3caa99e6c68f ("libipw: initiate cfg80211 API conversion (v2)") in 2009.

IMPORTANT INFORMATION BEFORE USING THIS DRIVER -================================================= - -Important Notice FOR ALL USERS OR DISTRIBUTORS!!!! - -Intel wireless LAN adapters are engineered, manufactured, tested, and -quality checked to ensure that they meet all necessary local and -governmental regulatory agency requirements for the regions that they -are designated and/or marked to ship into. Since wireless LANs are -generally unlicensed devices that share spectrum with radars, -satellites, and other licensed and unlicensed devices, it is sometimes -necessary to dynamically detect, avoid, and limit usage to avoid -interference with these devices. In many instances Intel is required to -provide test data to prove regional and local compliance to regional and -governmental regulations before certification or approval to use the -product is granted. Intel's wireless LAN's EEPROM, firmware, and -software driver are designed to carefully control parameters that affect -radio operation and to ensure electromagnetic compliance (EMC). These -parameters include, without limitation, RF power, spectrum usage, -channel scanning, and human exposure. - -For these reasons Intel cannot permit any manipulation by third parties -of the software provided in binary format with the wireless WLAN -adapters (e.g., the EEPROM and firmware). Furthermore, if you use any -patches, utilities, or code with the Intel wireless LAN adapters that -have been manipulated by an unauthorized party (i.e., patches, -utilities, or code (including open source code modifications) which have -not been validated by Intel), (i) you will be solely responsible for -ensuring the regulatory compliance of the products, (ii) Intel will bear -no liability, under any theory of liability for any issues associated -with the modified products, including without limitation, claims under -the warranty and/or issues arising from regulatory non-compliance, and -(iii) Intel will not provide or be required to assist in providing -support to any third parties for such modified products. - -Note: Many regulatory agencies consider Wireless LAN adapters to be -modules, and accordingly, condition system-level regulatory approval -upon receipt and review of test data documenting that the antennas and -system configuration do not cause the EMC and radio operation to be -non-compliant. - -The drivers available for download from SourceForge are provided as a -part of a development project. Conformance to local regulatory -requirements is the responsibility of the individual developer. As -such, if you are interested in deploying or shipping a driver as part of -solution intended to be used for purposes other than development, please -obtain a tested driver from Intel Customer Support at: - -https://www.intel.com/support/wireless/sb/CS-006408.htm - -1. Introduction -=============== - -This document provides a brief overview of the features supported by the -IPW2100 driver project. The main project website, where the latest -development version of the driver can be found, is: - - http://ipw2100.sourceforge.net - -There you can find the not only the latest releases, but also information about -potential fixes and patches, as well as links to the development mailing list -for the driver project. - - -2. Release git-1.1.5 Current Supported Features -=============================================== - -- Managed (BSS) and Ad-Hoc (IBSS) -- WEP (shared key and open) -- Wireless Tools support -- 802.1x (tested with XSupplicant 1.0.1) - -Enabled (but not supported) features: -- Monitor/RFMon mode -- WPA/WPA2 - -The distinction between officially supported and enabled is a reflection -on the amount of validation and interoperability testing that has been -performed on a given feature. - - -3. Command Line Parameters -========================== - -If the driver is built as a module, the following optional parameters are used -by entering them on the command line with the modprobe command using this -syntax:: - - modprobe ipw2100 [
