4a49ae94a4 ath10k: fix 10.4 extended peer stats update
10.4 'extended peer stats' will be not be appended with normal peer stats
data and they shall be coming in separate chunks. Fix this by maintaining
a separate linked list 'extender peer stats' for 10.4 and update
rx_duration for per station statistics. Also parse through beacon filter
(if enabled), to make sure we parse the extended peer stats properly.
This issue was exposed when more than one client is connected and
extended peer stats for 10.4 is enabled

The order for the stats is as below
S - standard peer stats, E- extended peer stats, B - beacon filter stats

{S1, S2, S3..} -> {B1, B2, B3..}(if available) -> {E1, E2, E3..}

7e247a9e88 ath10k: add dynamic tx mode switch config support for qca4019
push-pull mode needs certain amount the host driver involvement for
managing queues in the host memory and packet delivery to firmware.
qca4019 wifi firmware has an option to stay in push mode for less
number of active traffic flow and then switch to push-pull mode when
the active traffic flow goes beyond the certain limit.

The advantage of staying in push mode for less active traffic is, the
host cpu consumption is reduced. qca4019 firmware supports this
flexibility of the mode switch. It takes the host driver interest
(LOW_PERF/HIGH_PERF) via WMI_EXT_RESOURCE_CFG_CMDID,

 LOW_PERF  - fw would stay in push mode and switch to push-pull
               based on demand.
 HIGH_PERF - fw would stay in push-pull mode from the boot.

To make this configuration generic, new WMI services
WMI_SERVICE_TX_MODE_PUSH_ONLY, WMI_SERVICE_TX_MODE_PUSH_PULL,
WMI_SERVICE_TX_MODE_DYNAMIC are introduced to take dynamic tx mode
switch support availability in firmware.
Based on WMI_SERVICE_TX_MODE_DYNAMIC, LOW_PERF or HIGHT_PERF is
configured to the firmware.

b54e16f104 ath10k: fix peer assoc complete WMI command for 10.4
There is an extra 4-byte member when compared to WMI 10.2 added to
assoc complete command in WMI 10.4. This new member is used for 160Mhz
related configuration. This WMI command mismatch between host and
firmware does not cause any real issues because this new member is not
used in 10.4 firmwares so far (10.4.1.00030-1). This difference in WMI
command interface brings in a new wmi_ops for 10.4 gen_peer_assoc().
No noticeable functionality differences with this change can be seen
with the current 10.4 firmwares, but the WMI interface has to be
fixed to work with future 10.4 firmwares which may be using this new
member.

62f77f095c ath10k: enable adaptive CCA
European Union has made it mandatory that all devices working in 2.4 GHz
has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
beginnig this year. The standard basically speaks about interferences
in 2.4Ghz band.
For example, when 802.11 device detects interference, TX must be stopped
as long as interference is present.

Adaptive CCA is a feature, when enabled the device learns from the
environment and configures CCA levels adaptively. This will improve
detecting interferences and the device can stop trasmissions till the
interference is present eventually leading to good performances in
varying interference conditions.

The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
QCA988X.

a925a37639 ath10k: fix DMA alloc failure for target requested memory chunks
During long hours of stress testing like AP interface up/down along
with continuous ping flood from a station doing connect/disconnect,
it is observed that the system is not able to allocate DMA consistent
memory of size > 512KB chunks as requested by firmware in WMI_SERVICE_EVENTID.
With the system memory getting fragmented during the run based on the
size of the memory requested, the failure to return physically continguous
memory of high order can happen. Once the system gets to this situation,
bringing up the wifi interface will fail and a system reboot may be needed
to make it work again. This problem is obseved with QCA99X0.

To fix this issue, allocate the DMA memory requested by firmware during
device probe time and keep it during the life time of the device. WMI service
ready event handler is changed to allocate the memory chunks if it is
not already allocated or if the memory allocated for the previous ready
event is not same as the current requested ones. After this patch the
memory usage when wifi is inactive will be inceased by few 100KB to
3MB based on the target type.

Failure happens with the following stack trace

2b0a2e0d7c ath10k: handle 10.4 firmware phyerr event
Header format of 10.4 firmware phyerr event is not alligned
with pre 10.4 firmware. Introduce new wmi handlers to parse
10.4 firmware specific phyerror event header.

With changes covered in this patch, radar detection works on
qca9x0 hw 2.0 which uses 10.4 firmware.

991adf71a6 ath10k: refactor phyerr event handlers
Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. This is the problem in 10.4 fw
specific phyerr event handling where it uses different phyerror
header format. Before adding 10.4 specific handler, little bit of
refactor is done in existing phyerr handlers.

Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
firmware specific header format in the code. So that firmware specific
phyerror handlers can populate values to abstracted structures and
the following code can use abstracted struct for further operation.

.pull_phyerr_hdr is added newly to pull common phyerr header info
like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
handler is changed and called to parse every sub phyerrs in the event.

Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

3d2a2e293e ath10k: fix invalid survey reporting for QCA99X0
There are three WMI_CHAN_INFO events reported per channel
in QCA99X0 firmware. First one is a notification at the begining
of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
second one is a notification at the end of the dwell time with cmd_flag
CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
the channel. Since there is a new state before the completion, the handler
is to fixed so that the counts are deducted from the ones reported with
CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE.
Without this fix there will be lots of 0 msecs reported as active
and busy time.

3cec3be3d1 ath10k: handle 10.4 firmware wmi swba event
10.4 firmware swba event payload has space to accommodate upto
512 client traffic indication info & one p2p noa descriptor.
It's is not matching with exiting swba event format defined for
non 10.4 firmware. Non 10.4 firmware swba event format is designed
to support only upto only 128 client and four p2p notice of absence
descriptor.

following changes are done in this patch to enable ath10k to handle
10.4 firmware swba event,

 - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba
   event in 10.4 wmi rx handler.

 - add 10.4 specific swba event structure wmi_10_4_host_swba_event.

 - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse
   10.4 swba event.

 - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station
   power save state.

a03fee347c ath10k: enhance swba event handler to adapt different size tim bitmap
Due to 512 client support in 10.4 firmware, size of tim ie is going
to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
what is carried in swba event from 10.4 firmware is bit higher.

The only bottle neck to reuse existing swba handler
ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
This patch removes such size limitation and makes it more suitable
to handle swba event which has different size tim bitmap.

All existing swba event parsing functions are changed to adapt this
change. Actual support to handle 10.4 swba event is added in next patch.
Only preparation is made in this patch.
