[ANNOUNCE] d80211 based driver for Intel PRO/Wireless 3945ABG

[ANNOUNCE] d80211 based driver for Intel PRO/Wireless 3945ABG

[James Ketrenos]

Please hold all questions until I am done with this email.  Thank you.

We are pleased to announce the availability of a new driver for the 
Intel PRO/Wireless 3945ABG Network Connection adapter.  This new driver 
uses the new d80211 subsystem previously only available as part of the 
wireless-dev tree.

You can find the new driver, and additional information about it, here:

   http://intellinuxwireless.org/iwlwifi.

Within the new driver package are sources which we plan to submit for 
kernel inclusion as well as scripts and patches which create a version 
of the driver which can be loaded into kernels based on 2.6.18 and newer 
(provided you have installed the d80211 subsystem as well)  The README 
document can walk you through pretty quickly.

Since a lot of our users are not able to move to the latest versions of 
the Linux kernel, we have put together a d80211 package allowing the 
installation of the d80211 subsystem into an existing kernel image 
without the need to migrate to wireless-dev, or upgrade to a newer 
kernel at all (assuming you are using 2.6.18 or newer).

You can find that package at:

   http://intellinuxwireless.org/d80211

Ok.  Now... any questions?

Thanks,
James / Intel Corporation

The iwlwifi driver for the 3945 does not require the user space daemon, 
but does require a new microcode image.

Over the past year we were able to make the necessary changes to the 
microcode used with the 3945 such that we were able to remove the 
regulatory daemon.

Quote from the mentioned website:

"In addition to using the new d80211 subsystem, this project uses a
new microcode image which removes the need for the user space
regulatory daemon for this adapter"

I am impressed: I had 2.6.20 running with ipw3945 + wpa_supplicant. I
installed the d80211 system and the new driver, rebooted, and you won't
believe it, I had network connection even with WEP encryption.

That was a big surprise for me that it worked out of the box without any
magic.

If you are interested in any dmesg/log output, please let me know.


Ahhh ... one thing: The LED on my Acer Laptop (TM3012) does not show up,
maybe because I have CONFIG_D80211_LEDS off?

Again, thanks a lot for the good work!

Wow, great news on this rainy saturday! ;-)

The driver works perfectly, I'm writing this mail via wireless link. However 
there are two things to note:

The driver generates two network devices. The second one is for promicious 
mode? Is there any chance to disable the interface? ifrename renamed the 
wrong one to wlan0 and I had to tell my system to use eth1 for the wireless 
connection.

Second problem is that I can't unload the module. I get the message "FATAL: 
Module iwlwifi is in use." even if both interfaces are down.

Oh, I forgot one note: "make patch_kernel" is terribly broken. Any chance to

Very cool!  Is it likely that d80211 and iwlwifi will be pushed into
mainline in time for 2.6.21?

Hmmm...I think we need to spend a cycle or so in -mm.  2.6.22 seems
more likely for mainline.

I think we should take this as a goal.  Last time I checked, d80211 wasn't in
-mm.  Perhaps it should go there.  And by the way, the latest changes from
netdev->class_dev to netdev->dev break d80211.  Perhaps we should rebase
wireless-dev immediately after 2.6.21-rc1, fix all compile issues and submit
the patch to -mm.

And iwlwifi is surprisingly good for a just announced driver.  It worked for me
from the first attempt, and that's the first d80211 driver to do so.  In my
opinion, it should go to wireless-dev as soon as possible so it can go to -mm
toghether with other drivers.  A couple of wrinkles in the standalone build
system are irrelevant to the kernel interation.

The second one is the so-called "master" interface which is used for QoS
stuff. We're working on hiding it until a better solution for QoS
evolves (which has been a plan for a while.)

I've put up a new version of iwlwifi (0.0.6) with significant changes to 
the patch_kernel scripts as well as including Pavel's patch to KSRC.

I performed some build testing with 2.6.18 and wireless-dev @ commit 
f66e5aaa88c1c0a7ee6c6427d6535ed8afd35427 (Jan 8).

Let me know if it is still breaking.

Tried this is on a patched 2.6.20 kernel with ipw3945 device and it always 
puts the card in 802.11a mode instead of 802.11bg mode.

Ideas?

Before running  "iwconfig wlan0 channel 8",  the card is set to
802.11a mode. iwconfig shows rate at 54Mb/s. But after setting the
channel, it sets to 802.11b mode, and I can't find a way to change
from 11Mb/s to 54MB/s.

"iwlist eth0 rate" only show up to 11Mb/s.

So, my problem is the card is always in 802.11b mode.

Thanks,
Jeff.

So I guess there is a common problem with a/bg modes?

Yes... is there merged .git tree somewhere? I downloaded iwl git tree,
but it did not contain d80211 stack. I'm now downloading wireless-dev
git tree...

I would expect Intel to post patches some time soon to get into

Regardless of what iwconfig reports as the mode or rate, you should be 
able to associate to an AP in either spectrum (2.4 or 5.2) using any 
valid rate.  Once configured and associated, iwconfig should provide 
more correct information.

If association is failing, verify that 'iwlist scan' shows the AP and 
that you specify everything for the association, eg:

    iwconfig wlan0 channel 8 essid MyAP ap 00:13:f0:0d:ca:fe

d80211 will only attempt to associate once -- if it fails, then you need 
to currently "de-configure" the device and reconfigure it back to what 
you want to associate to.  I do that here by chaging the AP BSSID to 
something else then changing it back.  If you use wpa_supplicant, it 
does the re-association attempts for you.

Some of the patches contained in the d80211-1.0.1 'pending/' directory 
have already been submitted to netdev in the past.  The rest will be 
submitted soon (I would have liked them to have been submitted a few 
weeks back, but that slipped through my task list)

The d80211 packages I've pushed to date haven't done a very good job of 
accounting regarding the pending/ directory.  Those were the patches our 
team here had been working with internally, and I wanted to get them out 
to the users ASAP.  I'm working to get better descriptions added to the 
headers of those patches, as well as adding a status line indicating 
when the patches were submitted to the mailing lists for discussion.

The goal is to only include patches in the d80211 tarballs which have 
been submitted for eventual in-tree inclusion.

The LED code in iwlwifi isn't hooked up to the D80211 LED code yet.  If 
you'd file a bug at http://bughost.org regarding the LEDs being broken 
(if you haven't already) I would appreciate it.

There isn't a singular merged iwlwifi + d80211 package tree outside of 
wireless-dev, and iwlwifi isn't there yet (I'm cleaning out some dead 
and duplicated code before we submit)

I've put up http://intellinuxwireless.org/repos/?p=d80211.git so you can 
pull the d80211 package via git (vs. downloading the tarball).  Running 
'make patch_kernel' will then install the d80211 subsystem containing 
patches not yet in wireless-dev into your kernel sources (specified via 
KSRC=)

Ok, I was looking for merged tree. JBenc told me it should be
available "soon", so I guess I'll wait.

Good point(s).  Please try to use Documentation/SubmitChecklist,
as indicated in Andrew's -mm announcements (and copied in my sig below).

Hi!

> BUilding with sparse shows lots of warnings.

You seem to be the lucky one, able to actually compile the
beast. Could you run diff against vanilla and post it somewhere?

"Normal" installation procedure has too many steps in my eyes, and
combined git tree is not available, so I was waiting for merge at
least into -wirelessdev tree.
