[PATCH 00/10] iwlwifi driver 12/22 updates

[PATCH 00/10] iwlwifi driver 12/22 updates

[Zhu Yi]

Hi John,

Patches 7~9 are generic iwlwifi cleanup. Others are iwl3945 merging into
iwlagn patches, among which patch 10 should fix a regression reported by
Kalle Valo.

Thanks,
-yi

[PATCH 01/10] iwl3945: rearrange 3945 tfd
[PATCH 02/10] iwl3945: adding utils ops
[PATCH 03/10] iwl3945: sync tx queue data structure with iwlagn
[PATCH 04/10] iwl3945: remove iwl-3945-led.[ch]
[PATCH 05/10] iwl3945: switch to the iwl-core send_card_state routine
[PATCH 06/10] iwl3945: use iwl3945_tx_cmd instead of iwl_tx_cmd
[PATCH 07/10] iwlwifi: move sysfs status entry to debugfs
[PATCH 08/10] iwlwifi: kill retry_rate sysfs for iwlagn
[PATCH 09/10] iwlwifi: fix warning 'Should it be static'
[PATCH 10/10] iwl3945: use rx queue management infrastructure from iwlcore

[PATCH 01/10] iwl3945: rearrange 3945 tfd

[Zhu Yi]

From: Winkler, Tomas <tomas.winkler@intel.com>

This patch moves 3945 TFD structures to iwl-3945-fh.h. It renames them
similarly to AGN naming. This patch also eliminates iwl3945_tx_info and
fixes endianity issue in iwl3945_tx_skb and iwl3945_enqueue_hcmd caused
by ugly casting.

[PATCH 03/10] iwl3945: sync tx queue data structure with iwlagn

[Zhu Yi]

From: Samuel Ortiz <samuel.ortiz@intel.com>

We are now using the iwl_tx_queue for iwl3945. To reach that goal, we
included the 3945 specific tfd frame structure to iwl_tx_queue. This
has no effect on the current iwlagn code.

[PATCH 04/10] iwl3945: remove iwl-3945-led.[ch]

[Zhu Yi]

From: Samuel Ortiz <samuel.ortiz@intel.com>

We no longer need the 3945 specific LED files and structures. Remove
iwl-3945-led.[ch] and use iwl-led.[ch] instead.

http://marc.info/?l=linux-wireless&m=123000088608330&w=2 should fix the

Re: [PATCH 10/10] iwl3945: use rx queue management infrastructure from iwlcore

[Sedat Dilek]

Hiho,

No Xmas-bells ringing here.

I applied the patch-series 01/10 till 10/10 and afterwards I reverted
04_10_iwl3945-remove-iwl-3945-led.[ch].patch with Yi's revert-patch.

On the first sight, everything seems OK.
iwlist, wpa_cli gave the expected values back, but there is no DNS
resolved properly, e.g. ping.
This new state is also not usable for me :-).

What does this mean?
[...]

Do I need any mac80211-patches additionally?

The file exists:

Re: [PATCH 10/10] iwl3945: use rx queue management infrastructure from iwlcore

[Sedat Dilek]

The same error-message and as described before no DNS is resolved with
latest iwlwifi-2.6.git, also.
I added info about wpa_supplicant version I am using, maybe this is important.

Yes, that patch fixed it. Now my wifi is working again, thank you for
the present! :)

Just to be clear, these are the patches I have applied on top of
current wireless-testing:

Revert "iwl3945: remove iwl-3945-led.[ch]"
iwl3945: use rx queue management infrastructure from iwlcore
iwlwifi: fix warning 'Should it be static'
iwlwifi: kill retry_rate sysfs for iwlagn
iwlwifi: move sysfs status entry to debugfs
iwl3945: use iwl3945_tx_cmd instead of iwl_tx_cmd
iwl3945: switch to the iwl-core send_card_state routine
iwl3945: remove iwl-3945-led.[ch]
iwl3945: sync tx queue data structure with iwlagn
iwl3945: adding utils ops
iwl3945: rearrange 3945 tfd

If I spot any regressions, you will hear from me ;)

[Sedat Dilek]

With wireless-testing master-2008-12-23 (also plus 2.6.28-rc9-git4
patch) everthing OK in iwl3945-world.
Both Linux kernel works fine.
Thank you for the gift.
