99ffe72cda mwifiex: process rxba_sync event
Firmware may filter and drop packets under certain condition, for
example, ARP SA=DA packet. this event will be used to synchronize
the Rx Block Acknowledgment (BA) window bitmap and to fill any holes
in driver side.

c2a8f0ff9c mwifiex: support random MAC address for scanning
This patch advertises RANDOM_MAC_ADDR feature to cfg80211. It allow the
application to issue scan with a MAC address and mask. Random MACs are
generated and used in probe requests sent for scanning until it is changed
by the application or device is restarted.

Commit 97f2645f35 ("tree-wide: replace config_enabled() with
IS_ENABLED()") mostly did away with config_enabled().

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
tristate.

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.

When working in DQA mode, if a queue is shared and a HW restart
occurs, there might be a possible race condition between
stations on the queues, and an existing queue might be left
with no queues.

To solve this, make sure in DQA mode to re-assign the same
queues as before the HW restart.

When sending the SCD_QUEUE_CONFIG command, the queue is

use this TID on a different queue instead, it first needs to
be unassociated from the first queue.

Keep track for every queue what TID is associated with it.
