Subject: ath10k: read calibration data from Device Tree

This patch adds support for reading calibration data from Device Tree.
It looks for the calibration data in Device Tree if it can't find it
in a file. If there's no node in Device Tree, ath10k will try to find the
calibration data from OTP.

The node for the calibration data should be defined like this:

pci {
        pcie@0 {
                reg = <0 0 0 0 0>;
                #interrupt-cells = <1>;
                #size-cells = <2>;
                #address-cells = <3>;
                device_type = "pci";

                ath10k@0,0 {
                        reg = <0 0 0 0 0>;
                        device_type = "pci";
                        qcom,ath10k-calibration-data = [ 01 02 03 ... ];
                };
        };
};

Subject: ath10k: create ath10k_core_init_features()

It's easier to manage firmware version differences when we configure them in
one place. Rename ath10k_core_init_max_sta_count() to
ath10k_core_init_firmware_features() and start moving most of the firmware
version ("features") handling to that function.

Subject: ath10k: add ATH10K_FW_IE_WMI_OP_VERSION

Instead of using feature flags, add new 32 bit variable for managing different
WMI versions. This makes it firmware interface tests a bit less convoluted,
especially when we add one more interface.

From d7579d12c33f87de9975d17880d708b50e959bbb Mon Sep 17 00:00:00 2001
From: Michal Kazior <michal.kazior@tieto.com>
Date: Wed, 3 Dec 2014 10:10:54 +0200
Subject: ath10k: introduce wmi ops

Since the 10.x fw branch support was introduced it
became apparent ath10k will need to be able to
deal with different fw ABIs eventually.

The patch creates an abstraction for dealing with
command and event structures across different ABIs
and mostly gets rid of the
ATH10K_FW_FEATURE_WMI_10X flag usage.

Subject: ath10k: make some wmi functions public

Some functions can be shared across different WMI
ABIs. Make them public so different WMI backends
can use them from different source files in the
future.

From ca996ec5660874edaf7fab6939beaaa9e023d347 Mon Sep 17 00:00:00 2001
From: Michal Kazior <michal.kazior@tieto.com>
Date: Wed, 3 Dec 2014 10:11:32 +0200
Subject: ath10k: implement wmi-tlv backend

Latest main firmware branch introduced a new WMI
ABI called wmi-tlv. It is not a tlv strictly
speaking but something that resembles it because
it is ordered and may have duplicate id entries.

This prepares ath10k to support new hw.

Subject: ath10k: add new wmi interface of NF cal period

Introduce a new wmi interface controls noise floor (NF) calibration
period via debugfs as firmware has introduced it on v10.2.

It allows users to modify frequency of NF calibration in millisecond
and changes RSSI reporting frequency consequently.
Short calibration period will trigger more frequent NF calibration,
so that RSSI reported in receive frames is more realistic.

Till now calibration was done at 30 seconds.

Subject: ath10k: fix STA u-APSD

To comply with WMM-PS the device shouldn't wake up
with a NullFunc frame pair when tx-ing. Instead PM
bit on each tx frame should be used.

To make this work correctly firmware needs to be
told to use a different STA PS wake threshold when
u-APSD is enabled.

Subject: ath10k: prevent invalid ps timeout config

Setting 0 ps timeout to firmware yields very poor
latency and traffic issues. This is the case when
multi-vif is active.

Subject: ath10k: advertise p2p dev support

Firmware doesn't allow precise tx rate control so
P2P wasn't entirely spec compliant (it was using
CCK rates in some cases).

The only way to make sure firmware doesn't use CCK
rates is to have a vdev with P2P subtype used for
scanning and tx. This can be done via a special
dedicated P2P device interface support.

This also removes the ancient hack from ath10k in
favor of p2pdev.

To make it easier to manage firmware differences, we should not use
ATH10K_FW_FEATURE_WMI_10X outside ath10k_core_init_firmware_features(). To
achieve that create new field ar->max_num_vdevs and set it based on wmi op
version.

Subject: ath10k: add thermal cooling device support

Thermal cooling device support is added to control the temperature
by throttling the data transmission for the given duration. Throttling
is done using hw MAC quiet time setting. Period, duration and offset
from TBTT can be set up to quiet the MAC transmits for the required duty
cycle (% of quiet duration). The thermal device allows user to configure
duty cycle.

The quiet params are derived as follows.
	period = max(25TU, beacon interval / number of bss)
	duration = period * duty cycle / 100

Quiet mode can be disabled by setting the duty cycle to 0. The cooling
device can be found under /sys/class/thermal/cooling_deviceX/.
Corresponding soft link to this device can be found under phy folder.

/sys/class/ieee80211/phy*/device/cooling_device.

To set duty cycle as 40%,

echo 40 >/sys/class/ieee80211/phy*/device/cooling_device/cur_state

Subject: ath10k: add thermal sensor device support

Temperature sensor generates electrical analog voltage from temperature
of each chain. The analog voltage is converted to digital value through
ADC. For reading temperature values fom user space, hw monitoring device
is used.

Whenever the user requests for current temperature, the driver sends WMI
command and wait for response. For reading temperature,

cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input

Subject: ath10k: send (re)assoc peer command when NSS changed

Assoc peer command contain information about NSS.
When we will get IEEE80211_RC_NSS_CHANGED we should
also send (re) assoc peer command to be sure firmware
will know about it and RC will work correctly.

This was found during code review.

Subject: ath10k: set phymode to 11b when NO_OFDM flag set

phymode should use 11b only if NO_OFDM flags is set.
Hence check up channel flag for NO_OFDM and set to
11b.

Subject: iwlwifi: remove MODULE_VERSION

The module version "in-tree:" or "in-tree:d" is useless; there
should be better (functional) ways to detect whether debugging
is enabled and other than that the version says nothing.

Therefore remove the driver version completely.

Subject: iwlwifi: mvm: add fw runtime stack to dump data

The allocation of the DCCM between the data and the stack
can theoretically change without notice to the driver, but
the total size is HW-fixed. Since the stack CCM (runtime
stack) has also data important to the FW - this patch allows
pulling the whole DCCM in one piece and adds it to the dump
data.

If the size isn't known - just use the data part of the
DCCM as it appears in the FW TLVs.

From a054427244158552e91dacc0a4fc0a1b5e7342b9 Mon Sep 17 00:00:00 2001
From: Moshe Harel <moshe.harel@intel.com>
Date: Mon, 8 Dec 2014 21:13:14 +0200
Subject: iwlwifi: mvm: support LnP 1x1 antenna configuration

The antenna configuration has to be read also from OTP
Currently read only from FW image
Guideline: An antenna exists only if appears both in FW image & NVM

Subject: iwlwifi: mvm: rs: fix max rate allowed if no rate is allowed

In case the rate mask for one of the modulations was zero the
max rate idx for that modulation was set to 32 (BITS_PER_LONG).
This is bad as it would later lead to an out of bounds access
to the expected tpt table. In most cases there was no real effect
as the expected tpt was set to 0 and this led to avoiding the
modulation effectively.
Fix the out of bounds access and explicitly skip the modulation
in case there's no rate allowed in it.

Subject: iwlwifi: mvm: change SMEM dump to general purpose memory dump

Instead of adding a dump type for each type of memory, change
the SMEM type to be a general purpose memory dump. Add the
type of the memory and its offset in the device in the dump
itself. This will allow an external parser to know where
this memory came from.

Note that since this type isn't really in use yet, this is
not a real problem.

d3 and d0i3 shouldn't be mutually exclusive. Set supported
wowlan triggers by looking for each of them, and check

is supported by d0i3, and all the others by d3)

Subject: iwlwifi: support multiple d0i3 modes

Allow configuring additional d0i3 mode, in which the
fw will be configured to enter d0i3 only on suspend
(while keeping the wake_lock accounting as usual)

The d0i3 mode to use will be determined by the
underlying trans layer.

Consider the iwlwifi module param d0i3_disable when
considering whether d0i3 is supported.

(There is currently no need to differentiate between
supported and enabled, so keep the function as-is)

Subject: iwlwifi: mvm: wait for d0i3 exit on hw restart

On hw restart, make sure to wait for d0i3 exit
(by checking the IN_D0I3 status bit).

This is needed in order to avoid the stale
d0i3_exit_work from doing harm (e.g. unref
cleared reference).

Subject: iwlwifi: mvm: use iwl_mvm_sta_from_mac80211() consistently

A number of places (still) use a direct operation, use
iwl_mvm_sta_from_mac80211() consistently. In one place
also move it into the variable initializer.

Subject: iwlwifi: tlv: add support for IWL_UCODE_TLV_SDIO_ADMA_ADDR TLV

A new TLV supplies the ADMA address for SDIO mode, allowing
the driver to configure the default base address to be this
(as given in the FW), rather than hardcoding the values to
use until the FW sends the ALIVE message.

Use the value given by the FW in the IWL_UCODE_TLV_SDIO_ADMA_ADDR
TLV for setting the default SDTM base address until the FW sends
the ALIVE message. If it isn't given in the FW - use the current
hardcoded values.

Subject: iwlwifi: mvm: call to pcie_apply_destination also on family 8000 B
 step

In order to config the FW and to allocate monitor buffer driver should
run the function iwl_pcie_apply_destination immediately after FW sections
are loaded.

Subject: brcmfmac: Fix incorrect casting of 64 bit physical address.

The physical addresses being used by pcie and msgbuf were using
a cast to long, which incorrectly caused it to limit the address
to 32bit. Now explicit u64 is used where needed.

Subject: brcmfmac: Fix WEP configuration for AP mode.

When a device is configured for AP mode and it is configured for
WEP then the keys are plumbed first, followed by AP configuration.
During configuration a down command is given to the firmware which
will clear the configured keys. This patch reprograms the WEP keys
after AP has been brought up.

Subject: brcmfmac: Change error log in standard log for rxbufpost.

When there is no room in the ring for rxbufpost an error is logged,
however this happens quite frequently and can be considered normal
and is certainly recoverable. This patch changes the erorr into
a normal msgbuf log.

When user-space uses a valid ISO-3166-1 country code for its
regulatory domain selection, the driver will try to configure
the firmware to use the same.

Subject: mwifiex: module parameter for deep sleep configuration

This patch adds module parameter for auto deepsleep configuration.
By default, module_param is 0 and auto deep sleep is enabled.
If mwifiex driver is loaded with disable_auto_ds=1, deep sleep
configuration would not be downloaded to FW and FW would not enter
deepsleep upon initializing.

Subject: brcmfmac: Add support for bcm43340/1 wireless chipsets

This patch adds support for the bcm43340 and bcm43341 wireless
chipsets. These two chipsets are identical from wireless parts
perspective. As such they use the same firmware image.

Subject: mwifiex: do not send key material cmd when delete wep key

This patch fixes memory corruption reported by community developer.

"Memory corruption occurs in mwifiex_ret_802_11_key_material_v1()
when a short command response is received without a key length
causing non initialised memory to be interpreted as the key
length resulting in a memcpy() overwriting the part of the
driver's private data structure beyond the key area."

For v1 key material API firmwares, there is no need to send
command to delete WEP key. WEP encryption/decryption is controlled
by mac_control command.

This patch avoids sending key material command in del_key case.

Subject: mwifiex: get supported BA stream info from FW

This patch adds support to get number of BA streams
supported information from FW. Some newer chips(e.g. 8897 series)
support 4 BA streams for TX; so driver should not disallow BA stream
setup just after 2 streams have been established.

Subject: mwifiex: Adjust calling place of mwifiex_terminate_workqueue

Workqueue needs to be flushed early when removing card, otherwise
soft lockup issue may happen because main_process is triggered by
interrupt while card is being removed.

Subject: wil6210: use 'uint64_t' instead of 'cycles_t' to avoid warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

do_div() checks the type strictly. 'cycles_t' may be 32-bit under quite
a few architectures (parisc, arm, avr32 ...). So use 'uint64_t' instead
of, the related warning (with allmodconfig under parisc):

Subject: wlcore: add ability to reduce FW interrupts during suspend

Add the ability to mask FW interrupts on RX BA activity, PSM
entry/exit and fast-link notifications. This is used when the host
is suspended in order to decrease redundant wake ups.

Subject: wlcore: enable sleep during AP mode operation

Enable ELP authorization in AP mode and enable the use
of the wakeup bit in the ELP register.

Introduce AP role sleep configuration which is disabled
by default. When configured, it allows the AP to sleep
when ELP is authorized for it.

radar detection events from the fw to mac80211.

Bump fw name (to wl18xx-fw-4.bin) and min fw version
(to 8.9.*.*.11), and align event mailbox accordingly.

Subject: wlcore: add dfs master restart calls

call wlcore_cmd_dfs_master_restart when starting
the ap on a new channel (after csa is done).

Add a new WLVIF_FLAG_BEACON_DISABLED flag to
indicate that dfs_master_restart command
is required.

Subject: wlcore: allow using dfs channels

Since we are going to support dfs channels, there
is no reason to mark them as NO_IR (having
the DFS flag is enough anyway).

Additionally, when setting the regdomain configuration,
enable usable dfs channels.

Subject: rtlwifi: rtl8723be: Improve modinfo output

The description of the power-save variables for this driver is not as
clear as for the others. The wording is changed to match the others.

Subject: rtlwifi: Create new routine to initialize the DM tables

Each of the drivers contains a routine that initializes the dm_digtable
member of the driver's private area. As a first step toward reducing the
size of the drivers, a copy of this driver is created in rtlwifi, and the
definitions of the parameters are moved there.

Subject: rtlwifi: rtl8192c-common: Convert driver to use common DM table
 initialization

These changes convert both rtl8192ce and rtl8192cu to use the new routine.
Some additional definitions are needed in the core, thus several of the
headers for other drivers are affected, but no other executable code is
changed.

Subject: iwlwifi: mvm: fix EBS on single scan

EBS error detection isn't supported by all FWs, so turn it on
only if the FW advertises such support.

Subject: iwlwifi: mvm: drop non VO frames when flushing

This change has already been implemented in iwldvm:

commit a260e7b3f0307878b99d57ed1406cf2d497923b8
Author: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date:   Sun Oct 5 09:11:14 2014 +0300

    iwlwifi: dvm: drop non VO frames when flushing

Since I added the flush() callback implementation in mvm,
we got reports that the queues are stuck while roaming
or suspending.
This commit above helped much for iwldvm, implement the
same behavior for iwlmvm.

Subject: iwlwifi: mvm: set the tx cmd tid for BAR frame correctly

BAR tx cmd tid was set to non qos (8). This is wrong as BAR
should be sent with the tid of the BA session.
This led to a corruption in the firmware. The visible
effect of this from the driver side is the BA notification
that comes back after the BAR. It was botched and led to the
WARNING below.

From 3277213feb1b6625e4d7ad9eef1778dc88cdf46f Mon Sep 17 00:00:00 2001
From: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com>

Subject: wil6210: ADDBA/DELBA flows

Introduce BACK establishment procedures; decision logic is not implemented
yet; debugfs entry 'addba' used to manually trigger addba/delba for ringid 0.

debugfs usage:
to establish BACK with agg_wsize 16:
  echo 16 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba
to delete BACK:
  echo 0 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba
to change agg_wsize, one need to delete BACK and establish it anew

ADDBA flow for:

- originator

Tx side (initiator) sends WMI_VRING_BA_EN_CMDID providing
agg_wsize and timeout parameters.
Eventually, it gets event confirming BACK agreement - WMI_BA_STATUS_EVENTID
with negotiated parameters. On this event, update Tx vring data
(struct vring_tx_data) and display BACK parameters on debugfs

- recipient

Rx side (recipient) firmware informs driver about ADDBA with
WMI_RCP_ADDBA_REQ_EVENTID, driver process it in service work
queue wq_service. It adjusts parameters and sends response
with WMI_RCP_ADDBA_RESP_CMDID, and final confirmation provided
by firmware with WMI_ADDBA_RESP_SENT_EVENTID. In case of success,
driver updates Rx BACK reorder buffer.

policy for BACK parameters:
- aggregation size (agg_wsize * MPDUsize)) to not exceed 64Kbytes

DELBA flow for:

- originator

driver decides to terminate BACK, it sends WMI_VRING_BA_DIS_CMDID
and updates struct vring_tx_data associated with vring; ignore
WMI_DELBA_EVENTID.

- recipient

firmware informs driver with WMI_DELBA_EVENTID,
driver deletes correspondent reorder buffer

ADDBA request processing requires sending WMI command, therefore
it is processed in work queue context. Same work queue used as for
connect, it get renamed to wq_service

Subject: wil6210: simple ADDBA on originator (Tx) side

Upon Tx vring creation, initiate BACK establishment
with maximum possible window size.

When establishing secure connection, there is EAPOL data exchange
between connection itself and "data port open", where security
is done and non-EAPOL data may be transferred. It is better to
send EAPOL frames using normal ACK because of firmware considerations.

send ADDBA only is 2 conditions met:
- data port open for the corresponded STA
- vring created

Subject: wil6210: allow to configure ADDBA request

For manual ADDBA configuration, allow to set desired window size or
disable automatic mechanism.

Introduce module parameter (int) agg_wsize. It can be changed on run time,
will be taken into account on the next connect. Interpretation:
- <0 - disable automatic ADDBA; intended for manual testing through debugfs
- 0 - use automatically calculated window size
- >0 - use this for window size. Clipped by maximum supported by the hardware
with current environment.

Subject: wil6210: fix disconnect 1 STA in AP

When disconnecting single STA in AP, it might be that STA
in question is already disconnected. In this case, need to do nothing.
Previously, it was mis-interpreted as "disconnect all"

Subject: wil6210: improve debugfs for VRING

When printing VRING on debugfs (file "vrings"),
software head & tail indexes were printed in decimal format
while hardware tail in hexadecimal only.

It is not comfortable to compare indexes in different formats;
on the other hand, hexadecimal output useful to see hardware
glitches.

To serve all purposes, print hardware tail in both decimal and
hexadecimal formats.

When encapsulating 802.3 frames into the 802.11 ones,
8-byte SNAP header added to save ethtype. SNAP is part of
the frame body, thus should be counted in MSDU. So,
MTU = MSDU - SNAP

Subject: wil6210: rework debugfs for BACK

Enable more flexible control over block ack:
- allow addba for any Tx vring
- allow to specify block ack timeout
- allow to delba for Tx or Rx side of any agreement; with reason

Renamed "addba" entry to "back"; it prints short help when read;
write:
 - "add <ringid> <agg_size> <timeout>" to trigger ADDBA
If missing, <timeout> defaults to 0
 - "del_tx <ringid> <reason>" to trigger DELBA for Tx side
 - "del_rx <CID> <TID> <reason>" to trigger DELBA for Rx side
If missing, <reason> set to "STA_LEAVING" (36)

Subject: wil6210: use HW capabilities mask in reset

Use the proper reset follow based on HW capabilities
detection instead of chip ID.
Remove old hw ID mechanism which was used only for reset flow.
Remove support for Marlon A0.

Subject: wil6210: add advanced interrupt moderation

Add advanced interrupt moderation support available since "Sparrow B0".
Legacy interrupt moderation used only one counter to moderate tx, rx,
and misc interrupts.
Advanced interrupt moderation bypasses misc, and handles separately tx
and rx interrupts. In addition it has two timers for each interrupt type.
Max burst duration timer which defines how long to postpone interrupt after
first event (receive event for rx and tx complete event for tx), and
interframe timeout which defines how to determine the end of the burst and
issue interrupt even if the first timer still pending.
Capabilities flags in wil_priv is set on initialization according to
HW. The rest of the code checks for advanced interrupt capability bit
in capabilities flags field.
Debugfs is split accordingly: "legacy" interrupt moderation remains
unchanged, new debugs files added for advanced interrupt moderation
support.
Module params are aligned to support advanced interrupt moderation
(tx & rx). When not available (for legacy interrupt moderation) will
use only rx configuration; Tx configuration will be ignored in this
case.

Subject: wil6210: RX high threshold interrupt configuration

Rx high threshold interrupt is reported by the hardware in case
when number of not utilized by the HW descriptors in the Rx ring
becomes low.
Introduce module parameter for RX high threshold.

Subject: wil6210: fix reordering for MCAST

In the reordering block, Ethernet DA was checked for MCAST, this is wrong.
Check instead MCAST indication from 802.11 MAC header. Hardware saves
this into Rx descriptor.

Subject: wil6210: workaround for BACK establishment race

When establishing BACK, WMI may be handled earlier then Rx, in this case
late Rx will be mis-handled.

Detect early Rx and pass it to the stack, bypass reordering

Subject: wil6210: relax spinlocks in rx reorder

In the Rx reorder mechanism, nothing is done in the interrupt
context, so there is no need to use 'irq' flavors of spinlock.
Rx done in NAPI context (tasklet), other manipulations - in the
thread context.

Having interrupts enabled makes it better for the OS in general.
Besides, if enslaved under bonding, bridge or team driver, Rx
won't work with interrupts disabled.

Subject: ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file
 entries

Use the helper to get rid of the file operations per debugfs file. The
device driver data contains struct ieee80211_hw pointer and the
struct ath9k_softc pointer is assigned to ieee80211_hw::priv so it can
be accessed in the seq_file read operation.

Subject: ath9k: add power per-rate tables for AR9002 chips

Add TX power per-rate tables for MIMO/legacy modes for AR9002 based chips
in order to cap the maximum TX power value per-rate in the TX descriptor path.
Add TX power adjustments for HT40 mode, open loop CCK rates and eeprom power
bias for AR9280 and later chips

Subject: iwlwifi: mvm: abort scheduled scan upon RFKILL

When we have an active scheduled scan, and the RFKILL
interrupt kicks in, the stack will cancel the scheduled
scan as part of the down flow. But cancelling scheduled
scan usually implies sending a command to the firwmare
which has been killed as part of the RFKILL interrupt
handling.
Because of that, we returned an error to mac80211 when
it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.

To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.

This is basically the same as:

    iwlwifi: mvm: abort scan upon RFKILL

    This code existed but not for all the different FW APIs
    we support.
    Fix this.

Subject: iwlwifi: mvm: validate tid and sta_id in ba_notif

These are coming from the FW and are used to access arrays.
Bad values can cause an out of bounds access so discard
such ba_notifs and warn.

Subject: iwlwifi: mvm: rs: repeat initial legacy rates in LQ table

Repeating the legacy rates avoids degrading quickly to
lower rates due to collisions which is common when doing
TCP Tx traffic in legacy.
This slightly improves TCP Tx throughput while working
in legacy in different scenarios.

Subject: iwlwifi: mvm: allow to collect debug data from non-sleepable context

iwl_mvm_fw_dbg_collect allows to collect debug data from
the firmware. Most of the firmware interaction is done in
non-sleepable context. It makes little sense to force the
caller of iwl_mvm_fw_dbg_collect to sleep.
Defer the actual collection to a worker so that this
function will be able to be called from any context.

Subject: iwlwifi: mvm: set max_out_time equal to frag_passive_dwell in
 fragmented scan

Fragmented scan should be applied for all channels, passive and active.
When scanning on passive channels the firmware uses frag_passive_dwell
to define the maximum continuous scan time before returning to the
operating channel. On active channels max_out_time is the parameter
used by the firmware to define the maximum time allowed out of the
operating channel. Since active channels' scan should also be fragmented
set max_out_time equal to frag_passive_dwell.
In addition:
- Set max_out_time and suspend_time if the firmware doesn't support
  fragmented scan to avoid unexpected behavior.
- Adjust max_out_time for second level of scan precedence.

Use only basic dwell time (10 ms for active scan and 110 for passive),
regardless of the number of the probes and the band, if it is
supported by the FW. The FW will add 3 ms for each probe sent and 10
ms for low band channels.
Add a TLV flag to indicate such support in FW.

This fix is needed to fix few bugs regarding scans that take too much time.

Subject: iwlwifi: mvm: let the firmware configure the scheduler

A new host command can be used to configure the scheduler
instead of accessing the scheduler's registers from the
driver. This is easier and less error prone since accessing
the hardware at certain moments can lead to races with the
firmware.
Prefer to use the host command whenever it is available.

Subject: iwlwifi: mvm: add debugfs file for misbehaving U-APSD AP

As this functionality relies on getting a firmware notification
it is difficult to test. Allow accessing the data for it from
debugfs to be able to trigger all kinds of scenarios to test.

Subject: iwlwifi: mvm: add rxf and txf to dump data

When the FW is in error status - try to read the RXF and
TXF (all of them) and add them to the dump data.

This shouldn't happen in non-error statuses, as we don't
want to stop the RXF/TXF while they are running.

Subject: iwlwifi: correctly set the NMI register

When we want to trigger an NMI in the device, we need to set
bit 7 and not bit 0. However, older firmwares don't register
to the interrupt issued by bit 7. Use bit 7 first so that
the correct interrupt will be issued hoping that the firmware
will react. To be on the safe side, set bit 0 in case the
firmware didn't register to the proper interrupt.

From 93d17cceb2620440aa3171e90b0ea69a97ac305d Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Thu, 15 Jan 2015 12:59:26 +0100
Subject: iwlwifi: mvm: generate statistics debugfs code

There's no need to duplicate the structure field name in the string,
just generate the string in the macro that's there anyway. To keep
the debugfs output the same, rename one (otherwise unused) field.

Subject: iwlwifi: mvm: ignore temperature updates in the RX statistics
 notification

If the firmware sends spontaneous DTS notfications with the
temperature (indicated in a TLV), we can ignore the temperature we get
in the RX statistics notifications.  This prevents potentially
handling the same temperature change twice.  It also ignores
notifications with temperature equal to 0 that happens from time to
time.

Subject: iwlwifi: mvm: move U-APSD decision to authentication

In order to change the usage of U-APSD on the fly later,
move the enabling condition into a new function that is
called when authenticated.

This allows the module parameter to become writable, it
won't take effect immediately but at least on the next
association the new value will be used.

mac80211 will flush/drop the frames on the queues before
suspending / disconnecting.
It will then send the deauth and wait until the queues are
empty.

Subject: iwlwifi: mvm: rs: use STBC regardless of power save mode

Tx STBC was used only when in CAM mode or if powersave is disabled.
Effectively this meant we never used STBC as these modes aren't
used on most platforms by default. Change that.

Subject: iwlwifi: mvm: document switch case fall-through in
 iwl_mvm_send_sta_key

Add a comment indicating that the WLAN_CIPHER_SUITE_WEP104 case falls
through to the WLAN_CIPHER_SUITE_WEP40 case in iwl_mvm_send_sta_key.
This will document that the lack of a break is intentional.

Subject: iwlwifi: mvm: Do not consider invalid HW queues in queue mask

The iwl_mvm_mac_get_queues_mask() added vif->hw_queue[ac] to the
queue mask although it might be set to IEEE80211_INVAL_HW_QUEUE.
Fix it.

Subject: iwlwifi: mvm: use a new API for enabling STBC

The new API tells the FW that it's allowed to use STBC
but the FW will decide on its own whether to use STBC
or SISO (and in the future Beamformer).
Keep support for the old API which sets STBC explicitly
in the rates in the LQ table while we still support old
FW revisions.

The stats argument is always only passed as &mvm->drv_rx_stats, so
there's no point in passing it when the mvm pointer is passed.
Remove the argument entirely.

Subject: iwlwifi: pcie: support secured boot flow for family 8000 B step

The driver loads the 2 CPU sections, then it needs to let
the firmware know to start the authentication of the
sections. This is done by writing the relevants bits to
FH_UCODE_LOAD_STATUS.

For CPU1, the driver sets the lower 16 bits. For both CPUs,
the driver sets all the 32 bits.

Subject: iwlwifi: mvm: fix rx chains configuration in phy ctxt cmd

In the PHY_CTXT command sent to the FW the TX chains were
indeed configured by the values of both FW TLVs and of NVM,
but the RX chains were left out and configured only by FW
TLV.

This causes problems in 4165 HW, where there are 1x1
antennas, and the wrong configuration denies the driver
from connecting to the AP.

bd->tx_comp is a single bit in a bitfield, so assigning
"info->flags & IEEE80211_TX_CTL_REQ_TX_STATUS" only happens
to work because TX_STATUS is defined to BIT(0); if it were
any other bit this assignment would fail.

Subject: wcn36xx: let device generate qos seq numbers

wcn36xx currently sends an incorrect sequence number into the BA session
setup firmware command: it should be saving or updating the ssn in the
TX_START ampdu_action callback instead of waiting until TX_OPERATIONAL.
However, we can sidestep the issue by letting the hardware generate the
sequence numbers for QoS frames, as is done in prima, so do that.

Subject: wcn36xx: don't process 'valid' descriptors

The DMA engine will reset the valid bit after a descriptor is
complete; any with the valid bit still set may still be in
use by the hardware, so check that before freeing the descriptor.

Subject: wcn36xx: move set_tx_pdu inside set_tx_data/mgmt

The pdu is part of the buffer descriptor, so it makes
sense that one function would fill both.  Also, passing
the whole skb instead of just the header pointer to the
set_tx_data function paves the way for using its fields
for ampdu setup inside set_tx_data().

Subject: wcn36xx: initiate TX BA sessions

Currently, wcn36xx only asks for a TX BA session if it has
already established one for RX.  Thus, two wcn36xx devices cannot
do a-mpdu between themselves since they both wait for the other
to go first.  Fix this by starting a BA session after a few QoS
data frames have been sent to a STA.

Subject: rtlwifi/rtl8192de: remove redundant else if check

The else if check condition checks for the opposite of the
if check, hence the else if check is redundant and can be
replaced with a simple else:

if (rtlpriv->rtlhal.macphymode == SINGLEMAC_SINGLEPHY) {
	..
} else if (rtlpriv->rtlhal.macphymode != SINGLEMAC_SINGLEPHY) {
	..
}

replaced with:

if (rtlpriv->rtlhal.macphymode == SINGLEMAC_SINGLEPHY) {
	..
} else {
	..
}

Subject: atmel: Remove open-coded and wrong strcasecmp

The kernel's string library does in fact have strcasecmp, at least
since ded220bd8f08 ("[STRING]: Move strcasecmp/strncasecmp to
lib/string.c"). Moreover, this open-coded version is in fact wrong: If
the strings only differ in their last character, a and b have already
been incremented to point to the terminating NUL bytes, so they would
wrongly be treated as equal.
