77be2c54c5 mac80211: add vif to flush call
This will allow the low level driver to make decision based
on the vif such as queues etc...
Since the vif might be NULL, we can't add it to the tracing
functions.

1bbc09752d ath10k: refactor monitor code
It was possible to create/delete/start/stop
monitor vdev from a few places that were not
exclusively protected against each other. This
resulted in monitor vdev being stopped/removed by
one call origin while another one was expecting it
to continue running.

For example if CAC was started and interface's
promiscuous mode was toggled monitor vdev was
removed from the driver meaning no radar would be
detected. In additional a warning would be printed
upon CAC completion complaining it tried to stop
non-running monitor vdev.

The patch simplifies monitor code by removing
IEEE80211_HW_WANT_MONITOR_VIF (which wasn't really
ever needed) and improves state tracking. It also
unifies prints.

df5e85250a ath10k: deinit copy engine before resetting
Since copy engine allocation has been revised the
ath10k_pci_ce_deinit() now simply zeroes copy
engine registers. It's probably a good idea to do
that before reseting for a more graceful device
reset.

Before ath10k_pci_ce_deinit() freed copy engine
ringbuffer memory so it was required to call it
after resetting. Otherwise it was possible for
device to access unmapped/freed copy engine
ringbuffer memory.

25d0dbcbd5 ath10k: split ce initialization and allocation
Definitions by which copy engine structure are
allocated do not change so it doesn't make much
sense to re-create those structures each time
device is booted (e.g. due to firmware recovery).

This should decrease chance of memory allocation
failures.

While at it remove per_transfer_context pointer
indirection. The array has been trailing the copy
engine ringbuffer structure anyway. This also
saves pointer size worth of bytes for each copy
engine ringbuffer.

2289188c27 ath10k: fix rssi and rate reporting
RSSI and RATES fields are valid only when START_VALID
bit is set. So, in current implementation we have to
remember/caclulate them when START_VALID and report the same
when only END_VALID is set.
Currently during heavy traffic we could have:
- 10 packets with START_VALID - correct RSSI and RATES
- 10 packets with END_VALID
- 10 packets with START_VALID - correct RSSI and RATES
- 10 packets with END_VALID
...
Next using monitor interface we will see:
- 10 packets with correct rssi/rates
- 10 packets with rssi=-95/rate=6Mbps

Command WMI_FORCE_FW_HANG_CMDID is not supported in firmware 10.1.
In order to have firmware crash simulation functionality also
in firmware 10.1 driver can force firmware crash by performing not allowed
operation. Driver can deliberately crash firmware when setting vdev param for
vdev id out of range.  This patch introduces two keywords to simulate_fw_crash:

'soft' which will cause firmware crash that is recoverable
       by warm firmware reset but supported only in main firmware.
'hard' which will cause firmware crash recoverable by cold
       firmware reset, this option works for both firmwares.

Commands to trigger firmware soft/hard crash:

echo 'soft' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash
echo 'hard' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash

To protect from the race above, make sure NAPI won't process the same vring.
Introduce 'enabled' flag in the struct vring_tx_data. Proceed with Tx NAPI only if
'enabled' flag set. Prior to Tx vring release, clear this flag and make sure NAPI
get synchronized.

NAPI enablement status protected by wil->mutex, add protection where it was
missing and check for it.

During reset, disconnect all peers first, then proceed with the Rx vring. It allows for

9301ca90b6 ath9k_hw: set ANI firstep as absolute values instead of relative
On older chips, the INI value differ in similar ways as cycpwr_thr1, so
convert it to absolute values as well.

Since the ANI algorithm is different here compared to the old
implementation (fewer steps, controlled at a different point in time),
it makes sense to use values similar to what would be applied for newer
chips, just without relying on INI defaults.

28327fd096 ath9k_hw: set ANI cycpwr_thr1 as absolute values instead of relative
The table was copied from the ANI implementation of AR9300. It assumes
that the INI values contain a baseline value that is usable as reference
from which to increase/decrease based on the noise immunity value.

On older chips, the differences are bigger and especially AR5008/AR9001
are configured to much more sensitive values than what is useful.

Improve ANI behavior by reverting to the absolute values used in the
previous implementation (expressed as a simple formula instead of the
old table).

3b3e0efb5c ath9k: fix ready time of the multicast buffer queue
qi->tqi_readyTime is written directly to registers that expect
microseconds as unit instead of TU.
When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so
convert it to microseconds before passing it to ath9k_hw.

This should hopefully fix some Tx DMA issues with buffered multicast
frames in AP mode.

5998be8797 ath9k: Fix sequence number assignment for non-data frames
Since commit 558ff225de (ath9k: fix
ps-poll responses under a-mpdu sessions) non-data frames would have
gotten a sequence number from a TIDs sequence counter instead of
using the global sequence counter.

This can lead to instable connections.

To fix this only select the correct TID if we are processing a
data frame. Furthermore, prevent non-data frames to get a sequence
number from a TID sequence counter by adding a check to
ath_tx_setup_buffer.
