for all Intel ipw3945 users

http://www.pro-linux.de/news/2007/10827.html

James Ketrenos von Intel hat die Verfügbarkeit eines neuen Kernel-Treiber für Intel PRO/Wireless 3945ABG-Chips ("Golan") angekündigt.

Der neue Treiber iwlwifi beruht auf dem d80211-Subsystem und ist vollständig unter der GPLv2 lizenziert. Die aktuellen Treiber für diesen Chip setzen dagegen einen Userspace-Treiber voraus, der nur in Binärform ausgeliefert wird und die Einhaltung regulatorischer Vorgaben für die Frequenzbänder überwacht, ein Umstand, der Intel in der Vergangenheit einige Kritik eingebracht hat. Das OpenBSD-Projekt verweigerte gar die Aufnahme des Quellcodes und entwickelte einen eigenen Treiber, der komplett ohne Daemon auskommt.

iwlwifi umgeht das Problem, indem die problematischen Funktionen direkt in die Firmware ausgelagert werden. Einer Diskussion auf der Kernel-Mailingliste zufolge soll der Code zunächst in wireless-dev aufgenommen werden und einige Zeit in Andrew Mortons Entwicklungszweig getestet werden. Eine Aufnahme in den offiziellen Kernel wird nicht vor Version 2.6.22 erwartet.

For the non german speakers:

Intel will release a new driver for ipw3945 chips, completly under GPLv2, and the driver will go into kernel with 2.6.22 release

Thanks for the good news. I just wonder why they don't do the same with their audio cards stuff... hda-intel driver is so buggy. I still can't get my sound card to work properly... Anyway, that's OT.

Wonderful!

Functionalitywise I am extremely happy with all my Intel components (GM 945 an related components as well as the 3945ABG), so the only issues are/will have been the licensing.

Thanks for sharing this, ft!

Does anyone know if this driver will support package injection?

This was on the forums a few weeks ago. The driver has been available since that time.

Re: for all Intel ipw3945 users

Right, just the only who realized this was... you, the topic i chose was quite different tough, since the ipw driver is not the only driver affected by this change.

Anyway, you were right saying you still consider the driver as quite unstable. It actually is, the module sometimes crashes, it randomly disconencts and similar. I think there are a few good reasons why the driver actually won't be brought before 2.6.22. Also, i don't expect linus to release it into the current kernel if the driver isn't stable flagged.
