* Intel PRO/Wireless 2100 Driver Firmware
From: Marcus Laitala @ 2013-08-20 13:44 UTC (permalink / raw)
To: linux-wireless
I tried to download the Intel PRO/Wireless 2100 Driver Firmware
from: http://ipw2100.sourceforge.net/firmware.php
I only get the following error:
This webpage is not available"
As if the files/webpage is no longer there/online. I just wanted to
tell who ever is in charge of those that those files are no longer
downloadable.

* [PATCH 00/12] brcmsmac: bcm4313 iPA support
From: Arend van Spriel @ 2013-08-20 14:00 UTC (permalink / raw)
To: John W. Linville; +Cc: linux-wireless, Arend van Spriel
This series replaces the patch "brcmsmac: support 4313iPA" with
Message-ID: <1376130450-29746-13-git-send-email-arend@broadcom.com>.
That patch has been split up and other review comments from Jonas
Gorski have been taken into account.
The series is intended for v3.12 and applies to the master
branch of the wireless-next repository.
Arend van Spriel (12):
brcmsmac: cosmetic change in phy_lcn.c
brcmsmac: change pa_gain for bcm4313 iPA
brcmsmac: use ARRAY_SIZE in phytbl_lcn.c
brcmsmac: add debug info message providing phy and radio info
brcmsmac: update transmit gain table for lcn phy
brcmsmac: change lcnphy receive i/q calibration routine
brcmsmac: fix TSSI idle estimation
brcmsmac: avoid calling set_txpwr_by_index() twice
brcmsmac: rework switch control table init including iPA BT-combo
brcmsmac: correct phy registers for TSSI-based power control
brcmsmac: reinitialize TSSI power control upon channel switch
brcmsmac: add support for BCM4313 iPA variant

* [PATCH 02/12] brcmsmac: change pa_gain for bcm4313 iPA
From: Arend van Spriel @ 2013-08-20 14:00 UTC (permalink / raw)
To: John W. Linville; +Cc: linux-wireless, Arend van Spriel, Jonas Gorski
In-Reply-To: <1377007246-9957-1-git-send-email-arend@broadcom.com>
The function wlc_lcnphy_load_tx_gain_table() has a target PA
gain specified for the iPA variant of the bcm4313. This gain
value is reduced to avoid PA distortion. The if-statement is
removed because it was rather redundant in the first place.
Please note that this patch does not provide full iPA support.

Cleaning up some code fragments reducing indentation and uncluttering

made.

* [PATCH 09/12] brcmsmac: rework switch control table init including iPA BT-combo
From: Arend van Spriel @ 2013-08-20 14:00 UTC (permalink / raw)
To: John W. Linville; +Cc: linux-wireless, Arend van Spriel
In-Reply-To: <1377007246-9957-1-git-send-email-arend@broadcom.com>
Rework the code path in lcnphy tbl_init() for switch control
table programming. This also takes the iPA BT-combo card into
account.

* [PATCH 06/12] brcmsmac: change lcnphy receive i/q calibration routine
From: Arend van Spriel @ 2013-08-20 14:00 UTC (permalink / raw)
To: John W. Linville; +Cc: linux-wireless, Arend van Spriel, Jonas Gorski
In-Reply-To: <1377007246-9957-1-git-send-email-arend@broadcom.com>
The gain level control for the test tone has been changed. This
calbration test tone is used to determine the i/q compensation.
The i/q calibration routine has been reworked to accomodate this.

* [PATCH 03/12] brcmsmac: use ARRAY_SIZE in phytbl_lcn.c
From: Arend van Spriel @ 2013-08-20 14:00 UTC (permalink / raw)
To: John W. Linville; +Cc: linux-wireless, Arend van Spriel, Jonas Gorski
In-Reply-To: <1377007246-9957-1-git-send-email-arend@broadcom.com>
This patch converts all sizeof(x)/sizeof(x[0]) instances to
ARRAY_SIZE macro in phytbl_lcn.c. The patch was made using
spatch with ARRAY_SIZE.cocci (see [1]).

All code must check for needed headroom first, and copy packet
if space is not available. Since excess headroom is always safe,
most devices just always use the same worst case headroom.
Even with your changes this will still be necessary since packets will
be still in flight while features change.

I agree, it will always be necessary. I guess the question boils down to
whether/what N bytes headroom more or less actually make a difference.
The wireless stack currently sets needed_headroom to 34 or so I think,
but I will need to increase by 8 which was why I had this question to
start with. However, those 34 are an absolute worst case - in most cases
it's much less...
So I suppose the other question we should ask is will increasing from
~34 to ~42 make a significant different that it's worth thinking about
avoiding it in the common cases at all?

The only thing that might matter is alignment. but +/- 8 bytes isn't going
to change that.

I prefer having a flag to enable it over one to disable it, because it
fits better with the existing flags. Also, future drivers may not always
be properly prepared to handle CCK in A-MPDU sessions either.
By the way, I took a short look at brcmsmac and found more issues that
you should look into if you want to fix this.
First of all, you should probably make sure that the hardware does not
try to send an A-MPDU using a CCK rate (prepare it as a single frame in
brcms_c_ampdu_add_frame). It also does not seem to have any checks to
ensure that rate control probing frames are not aggregated.

* [PATCH 00/16] wcn36xx: mac80211 driver for Qualcomm WCN3660/WCN3680 hardware
From: Eugene Krasnikov @ 2013-08-20 17:41 UTC (permalink / raw)
To: linux-wireless; +Cc: wcn36xx, Eugene Krasnikov
This is a mac80211 driver for Qualcomm WCN3660/WCN3680 devices. So
far WCN3660/WCN3680 is available only on MSM platform.
To make review easier the driver sent in several patches, one patch per file, but after
review it will be sent as one big file.
Firmware can be found here:
https://github.com/AOKP/vendor_sony/find/jb-mr1
Wiki page is available here:
http://wireless.kernel.org/en/users/Drivers/wcn36xx
A lot people made a contribution to this driver. Her is the list in
alphabetical order:

Kalle Valo <kvalo@qca.qualcomm.com>
Olof Johansson <dev@skyshaper.net>
Pontus Fuchs <pontus.fuchs@gmail.com>
