6b03144d93 mwifiex: handle error if IRQ request fails in mwifiex_sdio_of()
When this failure occurs, we will clear card->plt_wake_cfg so that
device would initialize without wake up on external interrupt feature.
This feature specific code in suspend and resume handlers will be
skipped.

95b5bf7ccc ath10k: remove 4-addr padding related hw_param configuration
hw_4addr_pad was added to handle different types of padding
in 4-address rx frame. But this padding is not very specific
to 4-address, it can happen even with three address + ethernet
decap mode. Since the  padding information can be obtained
through Rx desc for QCA99X0 and newer chips, this hw_param
is not needed any more.

9e19e13261 ath10k: properly remove padding from the start of rx payload
In QCA99X0 (QCA99X0, QCA9984, QCA9888 and QCA4019) family chips,
hw adds padding at the begining of the rx payload to make L3
header 4-byte aligned. In the chips doing this type of padding,
the number of bytes padded will be indicated through msdu_end:info1.
Define a hw_rx_desc_ops wrapper to retrieve the number of padded
bytes and use this while doing undecap. This should fix padding
related issues with ethernt decap format with QCA99X0, QCA9984,
QCA9888 and QCA4019 hw.

ae02c8719a ath10k: add provision for Rx descriptor abstraction
There are slight differences in Rx hw descriptor information
among different chips. So far driver does not use those new
information for any functionalities, but there is one important
information which is available from QCA99X0 onwards to indicate
the number of bytes that hw padded at the begining of the rx
payload and this information is needed to undecap the rx
packet. Add an abstraction for Rx desc to make use of the
new desc information available. The callback that this patch
defines to retrieve the padding bytes will be used in follow-up
patch.

8c1d7fa531 ath10k: enable peer stats by default
IFTYPE_MESH_POINT need to rely on these for accurate path
selection metrics. Other modes will probably also find
them useful. Enabling peer stats has the side effect of
reducing max number of STAs from 128 to 118. There should
be negligible performance impact.

If users really need 128 STAs and don't mind losing out on
peer stats, they can still disable them:

78a9e17038 carl9170: Fix wrong completion usage
carl9170_usb_stop() is used from several places to flush and cleanup any
pending work. The normal pattern is to send a request and wait for the
irq handler to call complete(). The completion is not reinitialized
during normal operation and as the old comment indicates it is important
to keep calls to wait_for_completion_timeout() and complete() balanced.

Calling complete_all() brings this equilibirum out of balance and needs
to be fixed by a reinit_completion(). But that opens a small race
window. It is possible that the sequence of complete_all(),
reinit_completion() is faster than the wait_for_completion_timeout() can
do its work. The wake up is not lost but the done counter test is after
reinit_completion() has been executed. The only reason we don't see
carl9170_exec_cmd() hang forever is we use the timeout version of
wait_for_copletion().

Let's fix this by reinitializing the completion (that is just setting
done counter to 0) just before we send out an request. Now,
carl9170_usb_stop() can be sure a complete() call is enough to make
progess since there is only one waiter at max. This is a common pattern
also seen in various drivers which use completion.

cabd34d0e9 ath6kl: Allow the radio to report 0 dbm txpower without timing out
The ath6kl driver attempts to get the txpower value from the radio by first
clearing the existing stored value and then watching the value to become
non-zero.

APs allow setting client power to values from -127..127, but this radio
is not capable of setting values less then 0 and so will report txpower
as 0dbm for both negative and 0 client power values.

When the radio has txpower set to 0dbm txpower (equivalent to 1mw) the
ath6kl_cfg80211_get_txpower() function will remain in the
wait_event_interruptible_timeout() loop waiting for the value to be
non-zero, and will eventually timeout. This results in a 5 second delay in
response. However, the correct value of zero is eventually returned.

The 6004 defaults to 63dbm which is then limited by regulatory and
hardware limits with max of 18dbm (6003 max is 16dbm), therefore we can
use values larger then these to be able to determine when the value has
been updated.

To correct the issue, set the value to a nonsensical value (255) and wait
for it to change to the valid value.

Tested on both 6003 and 6004 based radios.  Return value of zero is
correctly returned in an expected amount of time (similar to when
returning non-zero values) when AP client power is set to both 0 and
negative values.

315c457ff1 ath9k: improve powersave filter handling
For non-aggregated frames, ath9k was leaving handling of powersave
filtered packets to mac80211. This can be too slow if the intermediate
queue is already filled with packets and mac80211 does not immediately
send a new packet via drv_tx().

Improve response time with filtered frames by triggering clearing the

18f53fe0f3 ath10k: fix throughput regression in multi client mode
commit 7a0adc83f3 ("ath10k: improve tx scheduling") is causing
severe throughput drop in multi client mode. This issue is originally
reported in veriwave setup with 50 clients with TCP downlink traffic.
While increasing number of clients, the average throughput drops
gradually. With 50 clients, the combined peak throughput is decreased
to 98 Mbps whereas reverting given commit restored it to 550 Mbps.

Processing txqs for every tx completion is causing overhead. Ideally for
management frame tx completion, pending txqs processing can be avoided.
The change partly reverts the commit "ath10k: improve tx scheduling".
Processing pending txqs after all skbs tx completion will yeild enough
room to burst tx frames.

3c97f5de1f ath10k: implement NAPI support
Add NAPI support for rx and tx completion. NAPI poll is scheduled
from interrupt handler. The design is as below

 - on interrupt
     - schedule napi and mask interrupts
 - on poll
   - process all pipes (no actual Tx/Rx)
   - process Rx within budget
   - if quota exceeds budget reschedule napi poll by returning budget
   - process Tx completions and update budget if necessary
   - process Tx fetch indications (pull-push)
   - push any other pending Tx (if possible)
   - before resched or napi completion replenish htt rx ring buffer
   - if work done < budget, complete napi poll and unmask interrupts

This change also get rid of two tasklets (intr_tq and txrx_compl_task).

Measured peak throughput with NAPI on IPQ4019 platform in controlled
environment. No noticeable reduction in throughput is seen and also
observed improvements in CPU usage. Approx. 15% CPU usage got reduced
in UDP uplink case.

7703773ef1 brcmfmac: fix pmksa->bssid usage
The struct cfg80211_pmksa defines its bssid field as:

    const u8 *bssid;

contrary to struct brcmf_pmksa, which uses:

    u8 bssid[ETH_ALEN];

Therefore in brcmf_cfg80211_del_pmksa(), &pmksa->bssid takes the address
of this field (of type u8**), not the one of its content (which would be
u8*).  Remove the & operator to make brcmf_dbg("%pM") and memcmp()
behave as expected.

This bug have been found using a custom static checker (which checks the
usage of %p... attributes at build time).  It has been introduced in
commit 6c404f34f2 ("brcmfmac: Cleanup pmksa cache handling code"),
which replaced pmksa->bssid by &pmksa->bssid while refactoring the code,
without modifying struct cfg80211_pmksa definition.

Replace &pmk[i].bssid with pmk[i].bssid too to make the code clearer,
this change does not affect the semantic.

Some RTL8821AE devices sold in Great Britain have the country code of

that establishes the regulatory info for the chip. The fix is to set
this code to have the same capabilities as the EU countries. In addition,
the channels allowed for COUNTRY_CODE_ETSI were more properly suited
for China and Israel, not the EU. This problem has also been fixed.

generated and used in probe requests sent for scanning until it is changed
by the application or device is restarted.

This is one of the postponed TODO items as config_enabled() is used
for a tristate option here.  Theoretically, config_enabled() is
equivalent to IS_BUILTIN(), but I guess IS_REACHABLE() is the best
fit for this case because both CONFIG_HWMON and CONFIG_ATH10K are

881ed54ecc ath10k: use complete() instead complete_all()
There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().

The usage pattern of the completion is:

waiter context                          waker context

scan.started
------------

ath10k_start_scan()
  lockdep_assert_held(conf_mutex)
  auth10k_wmi_start_scan()
  wait_for_completion_timeout(scan.started)

					ath10k_wmi_event_scan_start_failed()
					  complete(scan.started)

					ath10k_wmi_event_scan_started()
					  complete(scan.started)

scan.completed
--------------

ath10k_scan_stop()
  lockdep_assert_held(conf_mutex)
  ath10k_wmi_stop_scan()
  wait_for_completion_timeout(scan.completed)

					__ath10k_scan_finish()
					  complete(scan.completed)

scan.on_channel
---------------

ath10k_remain_on_channel()
  mutex_lock(conf_mutex)
  ath10k_start_scan()
  wait_for_completion_timeout(scan.on_channel)

					ath10k_wmi_event_scan_foreign_chan()
					  complete(scan.on_channel)

offchan_tx_completed
--------------------

ath10k_offchan_tx_work()
  mutex_lock(conf_mutex)
  reinit_completion(offchan_tx_completed)
  wait_for_completion_timeout(offchan_tx_completed)

					ath10k_report_offchain_tx()
					  complete(offchan_tx_completed)

install_key_done
----------------
ath10k_install_key()
  lockep_assert_held(conf_mutex)
  reinit_completion(install_key_done)
  wait_for_completion_timeout(install_key_done)

				        ath10k_htt_t2h_msg_handler()
					  complete(install_key_done)

vdev_setup_done
---------------

ath10k_monitor_vdev_start()
  lockdep_assert_held(conf_mutex)
   reinit_completion(vdev_setup_done)
  ath10k_vdev_setup_sync()
    wait_for_completion_timeout(vdev_setup_done)

					ath10k_wmi_event_vdev_start_resp()
					  complete(vdev_setup_done)

ath10k_monitor_vdev_stop()
  lockdep_assert_held(conf_mutex)
  reinit_completion(vdev_setup_done()
  ath10k_vdev_setup_sync()
    wait_for_completion_timeout(vdev_setup_done)

					ath10k_wmi_event_vdev_stopped()
					 complete(vdev_setup_done)

thermal.wmi_sync
----------------
ath10k_thermal_show_temp()
  mutex_lock(conf_mutex)
  reinit_completion(thermal.wmi_sync)
  wait_for_completion_timeout(thermal.wmi_sync)

					ath10k_thermal_event_temperature()
					  complete(thermal.wmi_sync)

bss_survey_done
---------------
ath10k_mac_update_bss_chan_survey
  lockdep_assert_held(conf_mutex)
  reinit_completion(bss_survey_done)
  wait_for_completion_timeout(bss_survey_done)

					ath10k_wmi_event_pdev_bss_chan_info()
					  complete(bss_survey_done)

All complete() calls happen while the conf_mutex is taken. That means
at max one waiter is possible.

e4fd726f21 ath10k: fix sending frame in management path in push txq logic
In the wake tx queue path, we are not checking if the frame to be sent
takes management path or not. For eg. QOS null func frame coming here will
take the management path. Since we are not incrementing the descriptor
counter (num_pending_mgmt_tx) w.r.t tx management, on tx completion it is
possible to see negative values.

When the above counter reaches a negative value, we will not be sending a
probe response out.

    if (is_presp &&
	ar->hw_params.max_probe_resp_desc_thres < htt->num_pending_mgmt_tx)

For IPQ4019, max_probe_resp_desc_thres (u32) is 24 is compared against
num_pending_mgmt_tx (int) and the above condtions comes true if the counter
is negative and we drop the probe response.

To avoid this, check on the wake tx queue path as well for the tx path of
the frame and increment the appropriate counters

83e164b767 ath10k: improve wake_tx_queue ops performance
txqs_lock is interfering with wake_tx_queue submitting more frames.
so queues don't get filled in and don't keep firmware/hardware busy
enough. This change helps to reduce the txqs_lock contention and
wake_tx_queue() blockage to being possible in txrx_unref().

To reduce turn around time of wake_tx_queue ops and to maintain fairness
among all txqs, the callback is updated to push first txq alone from
pending list for every wake_tx_queue call. Remaining txqs will be
processed later upon tx completion.

Below improvements are observed in push-only mode and validated on
IPQ4019 platform. With this change, in AP mode ~10Mbps increase is
observed in downlink (AP -> STA) traffic and approx. 5-10% of CPU
usage is reduced.

Major improvement is observed in 1-hop Mesh mode topology in 11ACVHT80.
Compared to Infra mode, CPU overhead is higher in Mesh mode due to path
lookup and no fast-xmit support. So reducing spin lock contention is
helping in Mesh.

47b1848d9f ath10k: fix spurious tx/rx during boot
HW Rx filters and masks are not configured
properly by firmware during boot sequences. The
MAC_PCU_ADDR1 is set to 0s instead of 1s which
allows the HW to ACK any frame that passes through
MAC_PCU_RX_FILTER. The MAC_PCU_RX_FILTER itself
is misconfigured on boot as well.

The combination of these bugs ended up with the
following manifestations:
 - "no channel configured; ignoring frame(s)!"
   warnings in the driver
 - spurious ACKs (transmission) on the air during
   firmware bootup sequences

The former was a long standing and known bug
originally though mostly harmless.

However Marek recently discovered that this
problem also involves ACKing *all* frames the HW
receives (including beacons ;). Such frames
are delivered to host and generate the former
warning as well.

This could be a problem with regulatory compliance
in some rare cases (e.g. Taiwan which forbids
transmissions on channel 36 which is the default
bootup channel on 5Ghz band cards). The good news
is that it'd require someone else to violate
regulatory first to coerce our device to generate
and transmit an ACK.

The problem could be reproduced in a rather busy
environment that has a lot of APs. The likelihood
could be increased by injecting an msleep() of
5000 or longer immediately after
ath10k_htt_setup() in ath10k_core_start().

The reason why the former warnings were only
showing up seldom is because the device was either
quickly reset again (i.e. during firmware probing)
or wmi vdev was created (which fixes hw and fw
states).

It is technically possible for host driver to
override adequate hw registers however this can't
work reliably because the bug root cause lies in
incorrect firmware state on boot (internal
structure used to program MAC_PCU_ADDR1 is not
properly initialized) and only vdev create/delete
events can fix it. This is why the patch takes
dummy vdev approach.

This could be fixed in firmware as well but having
this fixed in driver is more robust, most notably
when thinking of users of older firmware such as
999.999.0.636.

19aefa4594 iwlwifi: mvm: support txq tid owner change
Every active TXQ is assigned to a TID given through the
SCD_CONFIG_CMD, and acts as an identifier in the FW. However,
there may be cases this ownership needs to be changed.

For example, in the following scenario:
 1. TID x is owner of a queue
 2. Due to a shortage of queues, TID y and z share with x
 3. TID x becomes inactive and needs to be removed from the
    shared queue.
In this scenario, if another queue is freed and traffic on x
continues, we can't allocate it a new queue as long as it is
the owner of the first queue.

Support moving ownership of a TXQ to a different TID (same
STA) without stopping the queue.

b64abcb7da brcmfmac: Change vif_event_lock to spinlock
Change vif_event_lock to spinlock from mutex, since this lock is
used in wait_event_timeout() via vif_event_equals(). This caused
a warning report as below.

As far as I can see, this lock protects regions where updating
structure members, not function calls. Also, since those
regions are not called from interrupt handlers (of course, it
was a mutex), spin_lock is used instead of spin_lock_irqsave.

Check rtnl_lock is locked in brcmf_p2p_ifp_removed() by passing
rtnl_locked flag. Actually the caller brcmf_del_if() checks whether
the rtnl_lock is locked, but doesn't pass it to brcmf_p2p_ifp_removed().

Without this fix, wpa_supplicant goes softlockup with rtnl_lock
holding (this means all other process using netlink are locked up too)

2690c4c0e8 wil6210: fix wiphy registration sequence
Currently wiphy structure is initialized and registered
in wil_if_alloc, before some information is available such
as MAC address and capabilities. As a result there is a
small chance user space will get incorrect information
from calls such as NL80211_CMD_GET_WIPHY.
Fix this by seperating the registration and moving it
to wil_if_add which is executed later, after all
relevant information is known.

ef86f249fa wil6210: change HALP logging category to IRQ
Change the logging category of HALP functions from
MISC to IRQ, since the HALP mechanism is closely
related to interrupts. Both HALP and IRQ create
a heavy load of logging messages when enabled,
so their logging is typically disabled during normal debug
scenarios. Having them in the same logging category
will make it easier to disable logging for both in one go.

The reason is __dev_alloc_skb() may allocate larger buffer than required

2439ca0402 mac80211: Add ieee80211_hw pointer to get_expected_throughput
The variable is added to allow the driver an easy access to
it's own hw->priv when the op is invoked.

This fixes a crash in wlcore because it was relying on a
station pointer that wasn't initialized yet. It's the wrong
way to fix the crash, but it solves the problem for now and
it does make sense to have the hw pointer here.

97f2645f35 tree-wide: replace config_enabled() with IS_ENABLED()
The use of config_enabled() against config options is ambiguous.  In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED().  Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc.  makes the intention
clearer.

This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.

I noticed two cases where config_enabled() is used against a tristate
option:

 - config_enabled(CONFIG_HWMON)
  [ drivers/net/wireless/ath/ath10k/thermal.c ]

 - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
  [ drivers/gpu/drm/gma500/opregion.c ]

I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

it is already disconnected.

When enabling WLAN tethering, a new AP is visible and a STA could
connect to it. When the STA tries to authenticate to the newly created
AP, the WPA authentication mechanism is stuck in the 1/4 msg of 4-Way
Handshake.

In ath6kl_rx(), the ath6kl_find_sta() function is looking for the
h_source field of the Ethernet frame header received by the STA. The
datap pointer that points to the Ethernet frame header is incorrect,
and was pointing at the wrong offset in the buffer.

This commit adds a pad_before_data_start offset to set the datap pointer
to the Ethernet frame header. datap->h_source parameter is now really
pointing to the source ethernet address and the authentication process
can continue.

   The 'sta_rc_update' opcode is being used in mesh_plink.c.
Add support in wlcore to handle this opcode correctly for mesh
(as opposed to current implementation that handles STA only).
5. Bumped the firmware version to support new Mesh functionality

8cfb86003d mwifiex: Reduce endian conversion for REG Host Commands
For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS,
HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are
saved to driver. So, "leX_to_cpu" conversion is required too many
times afterwards in driver.

This patch reduces the endian: conversion without saving "cpu_to_leX"
converted values in driver. This will convert endianness in prepare
command and command response path.

As hw cycle counters in QCA4019 wraparound independantly in QCA4019
it is possible cycle counter and rx clear counter would wraparound
at the same time. Current logic assumes only one of the counters
would wraparound at anytime. Fix this by moving 'else' part to
another 'if'.

cfda2d8e23 ath9k: Fix beacon configuration for addition/removal of interfaces
This patch fixes some issues with interface reconfiguration. It could
for example happen that an AP interface in beacon slot 0 was removed
leaving an IBSS station in one of the other slots. When this happens
the driver never sends out the beacon as it only tries to send a beacon
from slot 0.

Appart from that the tracking of required changes to the beacon config is
relatively complicated and prone to errors.

The approach taken here is to solve reconfiguration issues is to
reconfigure the beacons when any interface changes. This means that
the complexity of deciding whether an interface change may modify the
beacon configuration is gone. It also means that the beacon config will
be reliably updated when an interface is removed.

The issue that a single non-AP interface might not be in beacon
slot 0 and wouldn't be send out is solved by moving it into the
first slot. The TSF value in hardware is adjusted accordingly so
that the timestamp of the beacons stay consistent.

bec9a94bc4 ath9k: Use tsf offset helper in ath9k_hw_reset
These changes make ath9k_hw_reset more consistent with other places that
handle the TSF value by using the same helper routine.

A slight improvement is to not assume that a fixed time of 1.5ms has
passed for the initval writes when compared to the first write attempt.
Instead the TSF value is re-calculated which will yield a higher accuracy
of the restored TSF timer.

fa5106e1d7 ath9k: Correct TSF adjustment to align the beacon time correctly
Beacons were not send out at (timestamp % beacon_time == 0) for interfaces
other than the primary one. To send out beacons with the correct timestamp
according to 10.1.3.2 of the 802.11 standard the tsf_adjustment has to be
set to the negative time difference instead of positive. This way the
later beacons get corrected to have a lower (and similar) timestamp with
regard to the beacon from slot 0.

I am not aware about any issues that have been caused by this.

dba8fbc67e brcmfmac: support removing AP interfaces with "interface_remove"
New firmwares (e.g. 10.10.69.36 for BCM4366) support "interface_remove"
for removing interfaces. Try to use this method on cfg80211 request. In
case of older firmwares (e.g. 7.35.177.56 for BCM43602 as I tested) this
will just result in firmware rejecting command and this won't change any
behavior.

a63b09872c brcmfmac: delete interface directly in code that sent fw request
So far when receiving event about in-firmware-interface removal our
event worker was notifying listener and afterwards it was removing Linux
interface.

First of all it was resulting in slightly unexpected order. The listener
(del_virtual_intf callback) was (usually) returning with success before
we even called unregister_netdev(ice).

Please note this couldn't be simply fixed by changing order of calls in
brcmf_fweh_handle_if_event as unregistering interface earlier could free
struct brcmf_if.

Another problem of current implementation are possible lockups. Focus on
the time slot between calling event handler and removing Linux
interface. During that time original caller may leave (unlocking rtnl
semaphore) *and* another call to the same code may be done (locking it
again). If that happens our event handler will stuck at removing Linux
interface, it won't handle another event and will block process holding
rtnl lock.

This can be simply solved by unregistering interface in a proper
callback, right after receiving confirmation event from firmware. This
only required modifying worker to don't unregister on its own if there
is someone waiting for the event.

scan_block flag is used to block scan operation when 4 way handshake

operation get canceled in some corner cases. As a result, further

34293f7558 ath10k: simplify pktlog htt event processing
It is expected that all pktlog events for 10.4 firmware based solutions
should come through CE8 where as in case of 10.2 firmware based solutions,
it should come through one of the HTT events (HTT_T2H_MSG_TYPE_PKTLOG).

But from experiments with 10.4 based solutions, it is observed that pktlog
event for ATH_PKTLOG_TYPE_TX_MSDU_ID is coming through HTT pktlog event.
Currently, we always parse with 10.2 pktlog header which will lead to
pktlog decoding issues (payload length mismatch exceptions)

For trace points, it is required to provide only the payload size. So
fixing this by simplifying the payload size calculation without the use of
ath10k pktlog headers.

While there, remove the unused ath10k pktlog headers.

Add the following to support beacon report radio measurement
with the measurement mode field set to passive or active:
1. Propagate the required scan duration to the device
2. Report the scan start time (in terms of TSF)
3. Report each BSS's detection time (also in terms of TSF)

TSF times refer to the BSS that the interface that requested the
scan is connected to.

1d76250bd3 nl80211: support beacon report scanning
Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.

In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.

Supporting beacon report is required for Multi Band Operation (MBO).

f16c3ebfa6 iwlwifi: pcie: fix a race in firmware loading flow
Upon firmware load interrupt (FH_TX), the ISR re-enables the
firmware load interrupt only to avoid races with other
flows as described in the commit below. When the firmware
is completely loaded, the thread that is loading the
firmware will enable all the interrupts to make sure that
the driver gets the ALIVE interrupt.
The problem with that is that the thread that is loading
the firmware is actually racing against the ISR and we can
get to the following situation:

CPU0					CPU1
iwl_pcie_load_given_ucode
	...
	iwl_pcie_load_firmware_chunk
		wait_for_interrupt
					<interrupt>
					ISR handles CSR_INT_BIT_FH_TX
					ISR wakes up the thread on CPU0
	/* enable all the interrupts
	 * to get the ALIVE interrupt
	 */
	iwl_enable_interrupts
					ISR re-enables CSR_INT_BIT_FH_TX only
	/* start the firmware */
	iwl_write32(trans, CSR_RESET, 0);

BUG! ALIVE interrupt will never arrive since it has been
masked by CPU1.

In order to fix that, change the ISR to first check if
STATUS_INT_ENABLED is set. If so, re-enable all the
interrupts. If STATUS_INT_ENABLED is clear, then we can
check what specific interrupt happened and re-enable only
that specific interrupt (RFKILL or FH_TX).

All the credit for the analysis goes to Kirtika who did the
actual debugging work.

21cb3222fe iwlwifi: decouple PCIe transport from mac80211
The PCIe transport needs to store two pointers in each TX SKB, and
currently assumes mac80211's ieee80211_tx_info is present in the CB
to do that.

In order to remove that assumption, have the opmodes pass in the
offset to where the pointers can be stored in the CB and use the
offset in the PCIe code.

To make the disentanglement complete, remove mac80211.h includes
from everywhere in the generic iwlwifi code. This required adding
an include of cfg80211.h in one place.

needs to be enabled in the driver before the CPU starts to
run.

Fix an issue where nullfunc frames and block ack requests
had the same tid as aggregation frames and were queued on
a non aggregation queue. The pending frames counter included
those frames but the check whether to decrement the pending

The result was an inconsistent state of the pending frames
counter followed by a failure to remove the station.
This failure triggered SYSASSERT 0x3421.

In addition, fix a situation in DQA mode where the number
of pending frames turned negative. This was due to the TX queue
being on the IWL_EMPTYING_HW_QUEUE_DELBA state and its frames
were still decremented.

We try to choose the lowest AC possible, to ensure the
shared queues have the lowest possible combined AC
requirements. The queue to share is chosen only from the
same RA's DATA queues as follows (in descending priority):
 1. An AC_BE queue
 2. Same AC queue
 3. Highest AC queue that is lower than new AC
 4. Any existing AC (there always is at least 1 DATA queue)

If any aggregations existed for any of the TIDs of the
shared queue - they are stopped (the FW is notified), but
no delBA is sent.

rtl_ps_set_rf_state() to be exported.

3ee7128579 mwifiex: add get_antenna support for cfg80211
Since commit de3bb771f4 ("cfg80211: add more warnings for inconsistent
ops") the wireless core warns if a driver implements a cfg80211 callback
but doesn't implements the inverse operation.

The mwifiex driver defines a .set_antenna handler but not a .get_antenna
so this not only makes the core to print a warning when creating a new
wiphy but also the antenna isn't reported to user-space apps such as iw.

This patch queries the antenna to the firmware so is properly reported to
user-space. With this patch, the wireless core does not warn anymore and:

$ iw phy phy0 info | grep Antennas
        Available Antennas: TX 0x3 RX 0x3

7d54bacadc mwifiex: add a cfg80211 .get_tx_power operation callback
The mwifiex driver implements a cfg80211 .set_tx_power operation handler
but doesn't have the inverse .get_tx_power callback.

This not only has the effect that the Tx power can't be reported to user
space tools such as iwconfig and iwlist but also that the wireless core
prints a warning when a new wiphy is created due an cfg80211 operation
being implemented without its counterpart.

After this patch, the Tx power is properly reported to user-space tools:

$ iwlist mlan0 txpower
mlan0     unknown transmit-power information.

          Current Tx-Power=13 dBm       (19 mW)

and also the following warning isn't shown anymore on the driver probe:

If driver writes RBD registers while MAC is asleep the
values are stored in shadow registers to be copied whenever

However, in 9000 devices a MAC wakeup is not triggered
and when the bus powers down due to inactivity the shadow
values and dirty bits are lost.
Turn on the chicken-bits that cause MAC wakeup for RX-related
values as well when the device is in D0.
When the device is in low power mode turn the RX wakeup chicken
bits off since driver is idle and this W/A is not needed.

e7e14089e9 iwlwifi: mvm: do not trust NSSN for amsdu sub-frames
We cannot trust NSSN for AMSDU sub-frames that are not the
last.
The reason is that NSSN advances on the first sub-frame,
and may cause the reorder buffer to advance before all the
sub-frames arrive.
Example:
Reorder buffer contains SN 0 & 2.
We receive AMSDU with SN 1 and NSSN for first sub frame 3.
The result us that driver releases SN 0,1, 2.
When sub-frame 1 arrives - reorder buffer is already ahead and
it will be dropped.
If the last sub-frame is not on this queue - we will get frame
release notification with up to date NSSN.

4bdd4dfe7a iwlwifi: advertise maximal MPDU length when Rx MQ is supported
The new hardware that supports multiple queue also
de-aggregates A-MSDUs. This means that we can advertise
the maximal size of A-MSDUs regardless of the receive
buffer's size.
In order to be able to forcefully use a lower A-MSDU size,
add a default value for the module parameter. Pre-9000
will have a default of 4K, and 9000 will have 12K.
Setting the amsdu_size module parameter to 4K will limit
the A-MSDU on 9000 as well.

569fba2cbb ath10k: remove unneccessary WARN_ON_ONCE in rx during ACS
The below warning message seems to hit occasionally with the following
combination (IPQ4019 + ACS scan) where we receive packets as a self peer
when hostapd does ACS when we bring up AP mode . ath10k has the below
fall back mechanism to fetch current operating channel in rx (it will
check for the next channel tracking variable if the current one is NULL)

	[scan channel] --> [rx channel] --> [peer channel] -->
	[vdev channel] -->  [any vdev channel] --> [target oper channel]

'scan channel' and 'target operating channel' are directly fetched from
firmware events. All the others should be updated by mac80211.

During ACS scan we wouldn't have a valid channel context
assigned from mac80211 ('ar->rx_channel'), and also relying on
('ar->scan_channel') is not helpful (it becomes NULL when it goes to
BSS channel and also when the scan event is completed). In short we
cannot always rely on these two channel tracking variables.

'Target Operating Channel' (ar->tgt_oper_chan) seems to keep track of
the current operating even while we are doing ACS scan and etc. Hence
remove this un-necessary warning message and continue with
target_operating channel. At the worst case scenario when the target
operating channel is invalid (NULL) we already have an ath10k warning
message to notify we really don't have a proper channel configured in
rx to update the rx status("no channel configured; ignoring frame(s)!")

fb7caababc ath10k: fix crash during card removal
Usually when the firmware crashes we check for the value
'FW_IND_EVENT_PENDING' in 'FW_INDICATOR_ADDRESS' and proceed with
disabling the irq and dumping firmware 'crash dump'. Now
when the PCI card is unplugged from the device the PCI controller
seems to generate a spurious interrupt after some time which
was as treated a firmware crash and resulting in the below race
condition (and eventually crashing the system)

	ath10k_core_unregister -> ath10k_core_free_board_files

	...... device unplug spurious interrupt .........

	ath10k_pci_taklet -> ath10k_pci_fw_crashed_dump  ...etc

Clearly even after the firmware board files related data structure
is freed up we are getting a spurious interrupt from PCI with 0xfffffff
in the 'FW_INDICATOR_ADDRESS' resulting in scheduling of the pci tasklet
and doing a crash dump, printing f/w board related info resulting in the
below crash. Fix this by detecting this spurious interrupt in ath10k PCI
irq handler itself and return IRQ_NONE. Thanks to Michal Kazior for
helping us conclude the most appropriate fix.

f21e4d8ed1 mac80211_hwsim: Allow wmediumd to attach to radios created in its netns
Registering wmediumd is currently limited to the initial network
namespace. This patch enables wmediumd to attach from non-initial
network namespaces using a user namespace having CAP_NET_ADMIN. A
registered wmediumd can forward frames on radios that have been created
in the same network namespace, even if they have been moved to other
network namespaces.

The wmediumd Netlink portid is tracked per net namespace. Additionally,
the portid is stored on all radios created in that net namespace to
simplify the portid lookup in the data path.

b50ddfa853 brcmfmac: fix lockup when removing P2P interface after event timeout
Removing P2P interface is handled by sending a proper request to the
firmware. On success firmware triggers an event and driver's handler
removes a matching interface.

However on event timeout we remove interface directly from the cfg80211
callback. Current code doesn't handle this case correctly as it always
assumes rtnl to be unlocked.

Fix it by adding an extra rtnl_locked parameter to functions and calling
unregister_netdevice when needed.

452fa86e98 libertas_tf: Remove create_workqueue
alloc_workqueue replaces deprecated create_workqueue().

A dedicated workqueue has been used since the workitem (viz
&priv->cmd_work per priv, which maps to lbtf_cmd_work) is involved in
actual command processing and may be used on a memory reclaim path.
The workitems require forward progress under memory pressure and hence,
WQ_MEM_RECLAIM has been set. Since there are only a fixed number of work
items, explicit concurrency limit is unnecessary here.

f568adac7d brcmfmac: slightly simplify building interface combinations
This change reorders some operations in brcmf_setup_ifmodes in hope to
make it simpler:
1) It allocates arrays right before filling them. This way it's easier
   to follow requested array length as it's immediately followed by
   code filling it. It's easier to check e.g. why we need 4 entries for
   P2P. Other than that it deduplicates some checks (e.g. for P2P).
2) It reorders code to first prepare limits and then define a new combo.
   Previously this was mixed (e.g. we were setting num of channels
   before preparing limits).
3) It modifies mbss code to use i variable just like other combos do.

2095b1426c mwifiex: fix link error against sdio
Calling sdio_claim_host() from the interface independent part of
the mwifiex driver is not only a layering violation, but also causes
a link error if MMC support is disabled, or if CONFIG_MMC=m
and CONFIG_MWIFIEX=y:

drivers/net/built-in.o: In function `mwifiex_fw_dpc':
:(.text+0xff138): undefined reference to `sdio_claim_host'
:(.text+0xff158): undefined reference to `sdio_release_host'

The right way to do this is to have the sdio specific code in the
sdio driver front-end, and we already have a callback pointer that
we can use for this after exporting the generic fw download
function from the core driver.

f9f905b00b libertas: Remove create_workqueue
alloc_workqueue replaces deprecated create_workqueue().

In if_sdio.c, the workqueue card->workqueue has workitem
&card->packet_worker, which is mapped to if_sdio_host_to_card_worker.
The workitem is involved in sending packets to firmware.
Forward progress under memory pressure is a requirement here.

In if_spi.c, the workqueue card->workqueue has workitem
&card->packet_worker, which is mapped to if_spi_host_to_card_worker.
The workitem is involved in sending command packets from the host.
Forward progress under memory pressure is a requirement here.

Dedicated workqueues have been used in both cases since the workitems
on the workqueues are involved in normal device operation with
WQ_MEM_RECLAIM set to gurantee forward progress under memory pressure.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary.

flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty. Hence the calls to flush_workqueue() before
destroy_workqueue() have been dropped.

The bus rx sequence is not in order because that control and event
frames always cause immediate send, but data frames may be held
for glomming in firmware side. It is not actually an error as the
packets are still processed even if the RX sequence is not in order.
Therefor the error message is rephrased and changed to a debug
message.

cb39288fd6 brcmfmac: use ndev->needed_headroom to reserve additional header space
When using nmap tool with FMAC, the nmap packets were be dropped by kernel
because the size was too short. The kernel message showed like
"nmap: packet size is too short (42 <= 50)". It is caused by the packet
length is shorter than ndev->hard_header_len. According to definition of
LL_RESERVED_SPACE() and hard_header_len, we should use hard_header_len
to reserve for L2 header, like ethernet header(ETH_HLEN) in our case and
use needed_headroom for the additional headroom needed by hardware.
