Subject: iwlwifi: improve oversized command warning

When warning about a command that is too large,
print out the command name/ID to help figure
out which place is attempting to send a command
that is too large.

Subject: iwlwifi: make data frame tracing optional

When tracing in iwlwifi, we get all data. Most of
the time, we don't need it, and it just takes up
a lot of extra space in the trace.

Make this optional by recording the data into two
separate trace events if it is needed. Without it,
record only the content of non-data and EAPOL TX
frames.

As a result, tracing without the data tracepoints
will record meta information including the 802.11
headers for all frames but will not record the
contents of data frames to reduce trace overhead.

When we disable a queue, we don't want the SCD to remember anything
about this queue (what packet was transmitted but not acked, what
packed was acked etc...).
Wipe out all this data in its SRAM.

Constify the arguments to iwl_write_targ_mem_dwords on the way.

Subject: iwlwifi: first deactivate a queue, then wipe out its data

Doing the opposite is wrong, the SCD wouldn't like someone
to clear its data while the queue is still active.

Subject: wireless: use OR operation to set wiphy features

The next patch will introduce a flag that is set
by default in cfg80211 so drivers and mac80211
need to use |= to set features they have so that
they don't clear the already-set feature.

We could set the flag in wiphy_register() instead
of wiphy_new() to avoid this patch, but then the
drivers couldn't *unset* flags they don't want to
use even though the implementation is generic.

Subject: wireless: drivers: make use of WLAN_EID_VENDOR_SPECIFIC

The include file linux/ieee80211.h contains three definitions for
the same thing in enum ieee80211_eid due to historic changes:

/* Information Element IDs */
enum ieee80211_eid {
    :
    WLAN_EID_WPA = 221,
    WLAN_EID_GENERIC = 221,
    WLAN_EID_VENDOR_SPECIFIC = 221,
    :
};

The standard refers to this as "vendor specific" element so the
other two definitions are better not used. This patch changes the
wireless drivers to use one definition, ie. WLAN_EID_VENDOR_SPECIFIC.

Subject: wireless: gelic: make use of WLAN_EID_VENDOR_SPECIFIC

The include file linux/ieee80211.h contains three definitions for
the same thing in enum ieee80211_eid due to historic changes:

    /* Information Element IDs */
    enum ieee80211_eid {
        :
        WLAN_EID_WPA = 221,
        WLAN_EID_GENERIC = 221,
        WLAN_EID_VENDOR_SPECIFIC = 221,
        :
    };

The standard refers to this as "vendor specific" element so the
other two definitions are better not used. This patch changes the
wireless drivers to use one definition, ie. WLAN_EID_VENDOR_SPECIFIC.

Subject: bcma: add an extra pcie core struct

The BCM4706 has two PCIe host controller on the bcma bus. For PCIe
client mode it is assumed that there is only one PCIe controller so the
PCIe driver, like b43 and brcmsmac are accessing the first PCIe
controller when they want to issue a operation on the host controller.

Subject: orinoco_usb: clean up some signedness issues

In ezusb_read_ltv() we had a comparison "(bufsize < 0)" which was never
true because bufsize was unsigned.  I looked at the implications of
that.  If we passed a negative number to ezusb_access_ltv() then it
would be used as the size parameter of the memcpy() because that
function uses min_t(int, exp_len, ans_size).

But fortunately when I looked at the callers, bufsize is not controlled
by the user and it's never negative.  So these signedness mistakes have
no impact.

I removed the always false check from ezusb_read_ltv() and I changed the
types in ezusb_access_ltv() and made the variables unsigned.

Subject: rtlwifi: rtl8192ce: rtl8192cu: use %*phC to dump small buffers

The patch changes a bit trace output format in the rtl_cam_program_entry() to
print prefix and the actual data on the same line. Moreover the %*phC outputs
each byte as 2 hex digits, which is slightly different to the original %x.

Subject: ath_hw: Use common REG_WRITE parameter order

All defines for REG_WRITE in Atheros wireless drivers use the order "ah",
"register" and "value". hw.c is the only file using the order "ah", "value" and
"register".

drivers/net/wireless/ath/ath9k/hw.h:#define REG_WRITE(_ah, _reg, _val) \
drivers/net/wireless/ath/key.c:#define REG_WRITE(_ah, _reg, _val) (common->ops->write)(_ah, _val, _reg)

This inconsistent definition can easily lead to implementation errors. The
modification doesn't change the behavior of the driver or the generated code.

Subject: rt2800: use BBP_R1 for setting tx power

TX power delta can be negative. TX_PWR_CFG_ registers allow to set delta
only in range between 0 dBm and 15 dBm (4 bits for each rate). Se we
need to use BBP_R1 to configure negative deltas.

Not utilize +6 dBm increasing BBP_R1 option for safety reason. For now,
this can be used for devices, which export maximum allowed TX power
value.

Based on AsicAdjustTxPower function from vendor driver
(2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO)
limit per rate TX power values we program into TX_PWR_CFG_ registers.

Note that on some configurations (devices/rates) is allowed to use
bigger values than 0xc, but we use safe maximum value for now. Further
work need to be done to allow use bigger values than 0xc.

Subject: rt2800: allow to reduce tx power on devices not exporting power limit

Some rt2800 devices don't have their calibrated max eirp tx power in
their calibration data. For those devices reduce tx power according to
difference between regulatory max channel power and requested tx power.

This patch is based on Helmut Schaa work.

Subject: carl9170: handle traps from firmware loader

This patch changes the way the driver deals with
command responses and traps which are sent through
the special interrupt input endpoint 3.

While the carl9170 firmware does not use this
endpoint for command responses or traps, the
firmware loader on the device does. It uses it
to notify the host about 'watchdog triggered'
in case the firmware/hardware has crashed.

Note:
Even without this patch, the driver is still
able to detect the mishap and reset the device.
But previously it did that because the trap
event caused an out-of-order message sequence
number error, which also triggered a reset.

Subject: ath9k: perform ANI cycle in idle state

As of now the ANI cycle is executed only when the chip is awake.
On idle state case, the station wakes up from network sleep for
beacon reception. Since most of the time, ANI cycle is not syncing
with beacon wakeup, ANI cycle is ignored. Approx 5 mins once, the
calibration is performed. This could affect the connection stability
when the station is idle for long. Even though the OFDM and CCK phy
error rates are too high, ANI is unable to tune its immunity level
as quick enough due to rare execution.

Here the experiment shows that OFDM and CCK levels are at default
even on higher phy error rate.

listenTime=44 OFDM:3 errs=121977/s CCK:2 errs=440818/s ofdm_turn=1

This change ensures that ANI calibration will be exectued atleast
once for every 10 seconds. The below result shows improvements and
immunity levels are adopted quick enough.

listenTime=557 OFDM:4 errs=752/s CCK:4 errs=125/s ofdm_turn=0

Subject: carl9170: fix spurious transmissions in sniffer mode

Several people have complained about an unusual
and undocumented feature of the AR9170 hardware:

In siffer mode, the hardware generates spurious
ACK frames for every received frame... even
broadcasts.

The reason for this malfunction is unknown:
<http://marc.info/?l=linux-wireless&m=134517238506033>
But there's a workaround: Instead of the special
sniffer mode, the hardware will be put into
station mode and all rx filters are disabled.

Subject: ath9k: Ensure we set FTP_STOMP_LOW weight when WLAN is idle

When WLAN is idle ensure we downgrade to FTP_STOMP_LOW weight
(from STOMP_LOW) to provide more bandwidth for BT FTP profile.
WLAN's idleness can be estimated by taking into account of the
rx data packets and just ignore beacons, qos nullfunc etc.

Also update bt_wait_time even if the chip is in NETWORK SLEEP
mode. This should help BT throughput when WLAN is idle.

Subject: ath9k: Add concurrent WLAN and BT tx support for MCI based chips

This feature enables both WLAN and BT can transmit simultaneously
by setting WLAN and BT to equal priorities. Whenever both are
transmitting, it might violate regulatory power limits. To avoid
regulatory violation, WLAN tx power will be adjusted according to BT
power index based on avaliability of BT scheduling message. If the
combined power exceeds threshold, BT transmission will be held off.

Subject: ath9k: fill channel mode in caldata

It is useful to have channel mode in caldata to find out
whether operaing channel is in HT40/20 when we are currently
on offchannel. It will be used by BTCOEX to enable/disable
concurrent tx mechanism later.

Subject: ath9k: adjust WLAN and BT concurrent transmission

The simulataneous transmission of both WLAN and BT might cause
increase in power levels. To avoid regulatory violation, WLAN tx
power will be adjusted according to BT power index based on avaliability
of BT scheduling messages. WLAN tx power reduction might affect its
performance. So WLAN tx power is only be lowered when the signal strength
is good enough. Otherwise concurrent tx will be disabled and WLAN uses
it default power levels. Also concurrent tx is disabled whenever WLAN is
moving to off-channel which might be used by BT.

Subject: ath9k_hw: Fix selfgen chainmask for 9565

Self generated MCI messages is configured to use chain 1. As
ar9565 is 1x1 solution, It can not use Chain 1. Hence fix
Chain 1 for ar9462 alone. Not doing so, could affect WLAN
connectivity in ar9565 as LNA sharing is not informed by BT.

Subject: ath9k_hw: Fix frequent BT rx recovery

While resuming from S3, BT host issues HCI reset command and it
causes BT firmware to busy with security key calculation. At this
movement, WLAN detects MCI hardware error of MCI_CONT_INFO_TIMEOUT
and then it starts the recovery sequence repeatedly. Too many
recovery sequences would exhaust the BT kernel message pool. This
patch imposes a duration between consecutive BT recovery procedure.
Thus it solves BT firmware panic issue reported in AR9565.

Whenever i_coff of IQ calibration is too high, AR9565 drops max
rx rate to MCS4. Skipping IQ update at this time can avoid this

Subject: ath9k: Add new BT profile info A2DP_Voice

When the BT connection is initiated by headset, it's possible that headset
requests to make one A2DP and one Voice connection over the same link.
BT firmware will send a new profile A2DP_Voice in this case. So WLAN
has to take care of this new profile for tuning BTCOEX parameters.

Subject: mwifiex: abort scan upon interface down

When the interface is down, we will abort scan by calling
cfg80211_scan_done() with abort option. This fixes WARN_ON
triggered by cfg80211 in wdev_cleanup_work().

Driver's internal variables/flags are cleared once we get
response for current scan command. Meanwhile we will block
new scan request from cfg80211.

Subject: mwifiex: minor cleanup and a fix in scan semaphore usage

mwifiex_request_scan() takes care of synchronous internal scan
performed by driver during association.
Currently the semaphore acquired for the scan is unnecessarily
released at the end of different paths. Also, failure paths
returning error code other than "-1" are not considered.

We will release it at the end of routine to fix above issues.

Subject: mwifiex: disable channel filtering for SSID specific scan from user

If MWIFIEX_DISABLE_CHAN_FILT bit in scan mode bitmap is set,
firmware will turn off the filtering of scan responses from
adjacent channels.

Currently the bit is set only for internal SSID specific scan
performed during association. We will set it for user requested
SSID specific scan as well.

Subject: Revert "mwifiex: retrieve correct max_power information in
 reg_notifier handler"

This reverts commit 34202e28fe7fc8551313f9a035a8857db83de757

We made "34202ee.." because we didn't support custom regulatory rules
at that time. But now we use our own custom regulatory rules, so it
needs to be changed back.

Also, chan->max_power calculations in cfg80211 were broken. Hence we
started using chan->max_reg_power. Now it has got fixed in
following commit.

commit 5e31fc0815a4e2c72b1b495fe7a0d8f9bfb9e4b4
Author: Stanislaw Gruszka <sgruszka@redhat.com>
Date:   Tue Jul 24 08:35:39 2012 +0200

    wireless: reg: restore previous behaviour of chan->max_power calculations

Hence we will use chan->max_power instead of chan->max_reg_power.

Subject: carl9170: split up carl9170_handle_mpdu

carl9170_handle_mpdu is the final part of the
rx path of the driver. It splits the raw data
streams from the device into skb packets and
passes them on to mac80211. As a result of
continuous updates, it grew over the years when
new code was added by the following commits:
	- report A-MPDU status
	- fix HT peer BA session corruption
	- A-MPDU frame type filter
	- ...

This patch splits the routine into two stages.
The first stage only deals with the details
about extracting and verifying the data from
the incoming stream. Whereas the second stage
packs it into skbs and passes it on to mac80211.

Subject: brcmfmac: extend struct brcmf_if with bssidx field

When the firmware notifies the driver about adding a new interface
it also provides an index for the bss associated with this interface.
This index will be needed for upcoming features like peer-to-peer.
By adding this index in struct brcmf_if it is easy to obtain as this
will be associated with the net_device private data.

Subject: brcmfmac: rework driver initialization in brcmf_bus_start()

In brcmf_bus_start() a number of settings are sent to the device. For
this functions are used that bypass the common firmware interface.
By reordering the code in brcmf_bus_start() this bypass can be removed.

Subject: brcmfmac: use bssidx from struct brcmf_if for bsscfg specific
 commands

The firmware interface has functions to send bsscfg specific commands
to the device. These functions currently have a bssidx parameter, but
that same information is stored in struct brcmf_if, which is in the
private data of the net_device parameter.

Subject: brcmfmac: add function converting ieee80211_channel to chanspec

The firmware carries channel information in a different format
as the provided ieee80211_channel structure. Conversion is needed
when receiving requests from cfg80211 carrying ieee80211_channel
structures. This patch adds a utility function to do that.

Subject: brcmfmac: use struct brcmf_if as interface object for fwil functions

The functions for communicating were given the net_device only because
its private data contained struct brcmf_if object. However, not all
firmware related interfaces will be associated with a net_device. To
accomodate provisioning firmware for such interfaces the struct
brcmf_if object will be passed to the fwil functions.

Subject: brcmfmac: change parameter list for send_key_to_dongle()

The first two parameters given to send_key_to_dongle() are redundant
so they have been removed.

Subject: brcmfmac: store profile information per virtual interface

The profile information applies to an interface so each virtual
interface needs it. So it is removed from brcmf_cfg80211_info
and added to brcmf_cfg80211_vif structure.

Subject: brcmfmac: use vif struct to check_sys_up() function

This checks the status that will soon be moved to virtual
interface data so preparing for that use the structure
brcmf_cfg80211_vif as parameter instead.

Subject: brcmfmac: remove debugfs functionality from wl_cfg80211.c

In wl_cfg80211.c debugfs directory was created to expose
dtim_period and beacon_interval. However, this can be easily
obtained using iw so it is removed from the driver.

Subject: brcmfmac: use memset when setting a broadcast mac address

The driver had a global constant ether_bcast, which was copied
whenever a broadcast mac address was needed. This patch does a
memset(dest, 0xFF, ETH_ALEN) instead and consequently removes
the global ether_bcast.

For AP feature the IEs are stored in global structure. For future
functionality like P2P-GO it needs to be stored per virtual interface
so better store it in the virtual interface structure.

Subject: ar5523: Add new driver

This driver is for the AR5523 chipset from Atheros. It was created
in 2007 by Christoph Hellwig but it was never finished. I found it a
couple of months ago and after some polishing it's working pretty
fine.

The driver was written with the FreeBSD driver (uath) as reference,
which was written with the reverse-engineered windows driver as
reference, hence the feature set is very limited. Station mode
only, no HW crypto offload.

Subject: ath9k_hw: Fix concurrent tx on lower tx power

Whenever WLAN receives scheduling msg from BT, it reduces tx power
based on RSSI level. And then BT starts simultaneous transmission
along with WLAN. Sometimes HW MAC compares tx power that is used
prior to power reduction which is causing BT transmission to defer.

Subject: rtlwifi: rtl8192c: rtl8192ce: Add support for B-CUT version of
 RTL8188CE

Realtek devices with designation RTL8188CE-VL have the so-called B-cut
of the wireless chip. This patch adds the special programming needed by
these devices. In addition, a variable that was static has been moved into
the private data area as it is now needed in two different routines. This
change also fixes a minor bug that would be present if a system had more
than one RTL81{88,92}CE devices. Other drivers in the rtlwifi family had
already made this change, thus the variable already exists in the private
data structure.

Subject: rtlwifi: rtl8192c: rtl8192ce: rtl8192cu: rtl8192se: rtl8192de:
 Shorten some variable names

The private data areas for these drivers contain some very long variable
names that cause difficulty in fitting source lines to an 80-character
limit.
