Subject: [PATCH 005/100] b43: bus: abstract SPROM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SPROM is another frequently used struct. We decided to share SPROM
struct between ssb na bcma as long as we will not need any hacks.

Subject: [PATCH 011/100] rt2x00: Enable PA_PE bits in TX_PIN_CFG according to
 active band.

(split off from the earlier RT35xx patch submitted by Shiang)

There's no point in enabling the PA_PE bits for the bands that we are
not active on.

Subject: [PATCH 014/100] rt2x00: Interface sequence lock doesn't have to
 disable interrupts.

This lock is only used in the TX path and thus in process context. Therefore
we can use a much lighter spinlock variant.

 rt2800_txdone_entry_check to rt2800usb.

These two functions are only used by rt2800usb so they don't have to be
in rt2800lib.

Subject: [PATCH 016/100] rt2x00: Enabled rt35xx device support by default.

Now that support for these devices has been added we can enable them
by default and remove the Kconfig not on support for these devices to
be non-functional.

Subject: [PATCH 017/100] mac80211_hwsim driver support userspace frame tx/rx

This patch adds to mac80211_hwsim the capability to send traffic via
userspace.

Frame exchange between kernel and user spaces is done through generic
netlink communication protocol. A new generic netlink family
MAC80211_HWSIM is proposed, this family contains three basic commands
HWSIM_CMD_REGISTER, which is the command used to register a new
traffic listener, HWSIM_CMD_FRAME, to exchange the frames from kernel
to user and vice-versa, and HWSIM_CMD_TX_INFO_FRAME which returns
from user all the information about retransmissions, rates, rx signal,
and so on.

How it works:

Once the driver is loaded the MAC80211_HWSIM family will be registered.
In the absence of userspace daemon, the driver itselfs implements a
perfect wireless medium as it did in the past. When a daemon sends a
HWSIM_CMD_REGISTER command, the module stores the application PID, and
from this moment all frames will be sent to the registered daemon.

The user space application will be in charge of process/forward all
frames broadcast by any mac80211_hwsim radio. If the user application
is stopped, the kernel module will detect the release of the socket
and it will switch back to in-kernel perfect channel simulation.

The userspace daemon must be waiting for incoming HWSIM_CMD_FRAME
commands sent from kernel, for each HWSIM_CMD_FRAME command the
application will try to broadcast this frame to all mac80211_hwsim
radios, however the application may decide to forward/drop this frame.
In the case of forwarding the frame, a new HWSIM_CMD_FRAME command will
be created, all necessary attributes will be populated and the frame
will be sent back to the kernel.

Also after the frame broadcast phase, a HWSIM_CMD_TX_INFO_FRAME
command will be sent from userspace to kernel, this command contains
all the information regarding the transmission, such as number of
tries, rates, ack signal, etc.

You can find the actual implementation of wireless mediumd daemon
(wmediumd) at:

Subject: [PATCH 019/100] ath9k: unify edma and non-edma tx code, improve tx
 fifo handling

EDMA based chips (AR9380+) have 8 Tx FIFO slots, which are used to fix the
tx queue start/stop race conditions which have to be worked around for
earlier chips by keeping the last descriptor in the queue. The current code
stores all frames that do not fit onto the 8 FIFO slots in a separate
list. Whenever a FIFO slot is freed up, the next frame (or A-MPDU) from the
pending queue gets moved to that slot.

This process is not only inefficient, but also unnecessary. The code can
be improved visibly by keeping the pending queue fully linked, and moving
the contents of the entire queue to a FIFO slot as it becomes available.

This patch makes the necessary changes for that and also merges some code
that was duplicated for EDMA vs non-EDMA. It changes txq->axq_link to point
to the last descriptor instead of the link pointer, so that
ath9k_hw_set_desc_link can be used, which works on all chips.

With this patch, a small performance increase for non-aggregated traffic
was observed on AR9380 based embedded hardware.

Subject: [PATCH 029/100] ath9k: Remove ATH9K_BEACON_PERIOD mask

Earlier beacon_interval is used to hold interval value and
some flags (ATH9K_BEACON_ENA &ATH9K_BEACON_PERIOD). So to
extract interval ATH9K_BEACON_PERIOD is used. Those flags
were completely removed. So masking beacon_interval is
not required.

Subject: [PATCH 031/100] nl80211: add testmode dump support

This adds dump support to testmode. The testmode
dump support in nl80211 requires using two of the
six cb->args, the rest can be used by the driver
to figure out where the dump position is at or to
store other data across invocations.

Subject: [PATCH 040/100] mwifiex: remove support for old chipsets W0/W1

For SD8787 A0/A1 chipsets we use the default firmware image
file 'mrvl/sd8787_uapsta.bin'. So the chip rev id variable
is removed.

The global variable fw_name is moved to adapter structure
so that we can support a different interface, such as PCIe,
in future.

the training power calculation indirectly depends on target power under
some scenarios, unless we have a valid training power, the PAPRD frames
won't be sent out. so when we get an invalid training power, its better
to display them before returning back.

Subject: [PATCH 050/100] iwlagn: fix dual-mode RXON

 The PAN context has three states: disabled, disassociated
 and associated. It seems that wasn't quite as much of an
 issue in previous versions of the microcode, but now we
 really have to use all the three states properly. So add
 code to switch accordingly.

Additionally, PAN parameters need to be sent differently
and the timing for PAN RXON needs to be inbetween.

Subject: [PATCH 060/100] iwlagn: fix channel switch locking

We use priv->mutex to avoid race conditions between iwl_chswitch_done()
and iwlagn_mac_channel_switch(), when marking channel switch in
progress. But iwl_chswitch_done() can be called in atomic context
from iwl_rx_csa() or with mutex already taken from iwlagn_commit_rxon().

These bugs were introduced by:

commit 79d07325502e73508f917475bc1617b60979dd94
Author: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date:   Thu May 6 08:54:11 2010 -0700

    iwlwifi: support channel switch offload in driver

To fix remove mutex from iwl_chswitch_done() and use atomic bitops for
marking channel switch pending.

Also remove iwl2030_hw_channel_switch() since 2000 series adapters are
2.4GHz only devices.

Subject: [PATCH 062/100] libertas_sdio: handle spurious interrupts

Commit 06e8935febe687e2a561707d4c7ca4245d261dbe adds an IRQ handling
optimization for single-function SDIO cards like this one, but at the
same time exposes a small hardware bug.

During hardware init, an interrupt is generated with (apparently) no
source. Previously, mmc threw this interrupt away, but now (due to the
optimization), the mmc layer passes this onto libertas, before it is ready
(and before it has enabled interrupts), causing a crash.

Work around this hardware bug by registering the IRQ handler later and
making it capable of handling interrupts with no cause. The change that
makes the IRQ handler registration happen later actually eliminates
the spurious interrupt as well.

Subject: [PATCH 067/100] rtlwifi: Don't block interrupts in spinlocks

Now power state transitions are not called from an
interrupt context, there's no need to block interrupts.

This code appears to block interrupts for too long,
causing my trackpad to lose sync occasionally.

Subject: [PATCH 071/100] lib: crc8: add new library module providing crc8
 algorithm

The brcm80211 driver in staging tree uses a crc8 function. Based on
feedback from John Linville to move this to lib directory, the linux
source has been searched. Although there is currently only one other
kernel driver using this algorithm (ie. drivers/ssb) we are providing
this as a library function for others to use.

Subject: [PATCH 072/100] lib: cordic: add library module providing cordic
 angle calculation

The brcm80211 driver in the staging tree has a cordic function to
determine cosine and sine for a given angle. Feedback received from
John Linville suggested that these kind of functions should be made
available to others as a library function in the kernel tree. The
b43 driver also has a cordic angle calculation implemented.

Subject: [PATCH 074/100] b43: do not use SSB specific flags when calling core
 reset function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Luckily the only flag we use when calling core reset is GMODE one.
Thanks to that we can just switch to single bool and make function calls
bus generic.

Tested on my BCM4312 (LP-PHY) and early tested with BCM43224.

Subject: [PATCH 075/100] bcma: read SPROM and extract MAC from it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In case of BCMA cards SPROM is located in the ChipCommon core, it is
not mapped as separated host window. So far we have met only SPROMs rev
8.
SPROM layout seems to be the same as for SSB buses, so we decided to
share SPROM struct and some defines.
For now we extract MAC address only, this can be improved of course.

Subject: [PATCH 076/100] b43: add an option to register BROKEN bcma driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It does nothing useful yet, so it is matched as BROKEN.
For now this is just an option for b43, in future we may want to make
b43 support SSB or BCMA (note: or, not xor).

Subject: [PATCH 089/100] iwlagn: use cts-to-self protection on 5000 adapters
 series

This patch fixes 802.11n stability and performance regression we have
since 2.6.35. It boost performance on my 5GHz N-only network from about
5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz.

These are test results of 5x downloading of approximately 700MB iso
image:

vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110
patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946

This was achieved with NetworkManager configured to do not perform
periodical scans, by configuring constant BSSID. With periodical scans,
after some time, performance downgrade to unpatched driver level, like
in example below:

patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683

However patch still make better here, since similar test on unpatched
driver make link disconnects with below messages after some time:

wlan1: authenticate with 00:23:69:35:d1:3f (try 1)
wlan1: authenticate with 00:23:69:35:d1:3f (try 2)
wlan1: authenticate with 00:23:69:35:d1:3f (try 3)
wlan1: authentication with 00:23:69:35:d1:3f timed out

On 2.6.35 kernel patch helps against connection hangs with messages:

iwlagn 0000:20:00.0: queue 10 stuck 3 time. Fw reload.
iwlagn 0000:20:00.0: On demand firmware reload
iwlagn 0000:20:00.0: Stopping AGG while state not ON or starting

Subject: [PATCH 091/100] iwl4965: set tx power after rxon_assoc

Setting tx power can be deferred during scan or changing channel.
If after that correct tx power settings will not be sent to device,
we can observe transmission problems and timeouts. Force to send
tx power settings also after partial rxon change, to assure device
always be configured with up-to-date settings.

Subject: [PATCH 092/100] mac80211: Stop BA session event from device

Some devices support BT/WLAN co-existence algorigthms.
In order not to harm the system performance and user experience, the device
requests not to allow any RX BA session and tear down existing RX BA sessions
based on system constraints such as periodic BT activity that needs to limit
WLAN activity (eg.SCO or A2DP).
In such cases, the intention is to limit the duration of the RX PPDU and
therefore prevent the peer device to use A-MPDU aggregation.

Adding ieee80211_stop_rx_ba_session() callback
that can be used by the driver to stop existing BA sessions.

Subject: [PATCH 096/100] mwifiex: remove list traversal in
 mwifiex_num_pkts_in_txq

Instead of counting the number of packets in txq
for particular RA list before AMSDU creation,
maintain a counter which will keep track of the
same.

This will reduce some MIPS while generating AMSDU
traffic as we only have to check the counter instead
of traversing through skb list.

Subject: [PATCH 098/100] mwifiex: adding check for enough space before padding

All MSDUs, except the last one in an AMSDU, should end up at 4
bytes boundary. There is need to check if enough skb_tailroom
space exists before padding the skb.

Also re-arranging code for better readablity.

Subject: [PATCH 099/100] mwifiex: disable transmission buffer aggregation for
 AMSDU packets

Padding per MSDU will affect the length of next packet and hence
the exact length of next packet is uncertain here.

Also, aggregation of transmission buffer, while downloading the
data to the card, wont gain much on the AMSDU packets as the AMSDU
packets utilizes the transmission buffer space to the maximum
(adapter->tx_buf_size).
