CCK hardware table mapping from QCA99X0 onwards got revised.
The CCK hardware rate values are in a proper order wrt. to
rate and preamble as below
ATH10K_HW_RATE_REV2_CCK_LP_1M = 1,
ATH10K_HW_RATE_REV2_CCK_LP_2M = 2,
ATH10K_HW_RATE_REV2_CCK_LP_5_5M = 3,
ATH10K_HW_RATE_REV2_CCK_LP_11M = 4,
ATH10K_HW_RATE_REV2_CCK_SP_2M = 5,
ATH10K_HW_RATE_REV2_CCK_SP_5_5M = 6,
ATH10K_HW_RATE_REV2_CCK_SP_11M = 7,
This results in reporting of rx frames (with CCK rates)
totally wrong for QCA99X0, QCA4019. Fix this by having
separate CCK rate table for these chipsets with rev2 suffix
and registering the correct rate mapping to mac80211 based on
the new hw_param (introduced) 'cck_rate_map_rev2' which shall
be true for any newchipsets from QCA99X0 onwards

During hw scan, firmware sends two channel information events (pre-
complete, complete) to host for each channel change. The snap shot of cycle
counters (rx_clear and total) between these two events are given for
survey dump. In order to get latest survey statistics of all channels, a
scan request has to be issued. In general, an AP DUT is brought up, it
won't leave BSS channel except few cases like overlapping bss or radar
detection. So survey statistics of bss channel is always referring to
older data that are collected before starting AP (either ACS/OBSS scan).
To collect latest survey information from target, firmware provides WMI
interface to read cycle counters from hardware. For each survey dump
request, BSS channel cycle counters are read and cleared in hardware.
This makes sure that behavior is in align with ath9k survey report.
So survey dump always gives snap shot of cycle counters b/w two survey
requests.

According to the spec, VHT doesn't exist in 2.4GHz.
There are vendor extensions to allow a subset of VHT to work
(notably 256-QAM), but since mac80211 doesn't support those
advertising VHT capability on 2.4GHz leads to the behaviour
of reporting VHT capabilities but not being able to use any
of them due to mac80211's code requiring 80 MHz support.
Remove the VHT capabilities from 2.4GHz for now. If mac80211
gets extended to use the (likely Broadcom) vendor IEs for it
and handles the lack of 80 MHz support, it can be added back.

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.

Upon firmware assert, restart work will be triggered so that mac80211
will reconfigure the driver. An issue is reported that after restart
work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info
for operating channel. During reconfigure, since mac80211 already has
valid channel context for given radio, channel context iteration return
num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning
channel context to rx_channel when driver restart is in progress.

Frames that are transmitted via MGMT_TX are using reserved descriptor
slots in firmware. This limitation is for the htt_mgmt_tx path itself,
not for mgmt frames per se. In 16 MBSSID scenario, these reserved slots
will be easy exhausted due to frequent probe responses. So for 10.4
based solutions, probe responses are limited by a threshold (24).
management tx path is separate for all except tlv based solutions. Since
tlv solutions (qca6174 & qca9377) do not support 16 AP interfaces, it is
safe to move management descriptor limitation check under mgmt_tx
function. Though CPU improvement is negligible, unlikely conditions or
never hit conditions in hot path can be avoided on data transmission.

The current/old tx path design was that host, at
its own leisure, pushed tx frames to the device.
For HTT there was ~1000-1400 msdu queue depth.
After reaching that limit the driver would request
mac80211 to stop queues. There was little control
over what packets got in there as far as
DA/RA was considered so it was rather easy to
starve per-station traffic flows.
With MU-MIMO this became a significant problem
because the queue depth was insufficient to buffer
frames from multiple clients (which could have
different signal quality and capabilities) in an
efficient fashion.
Hence the new tx path in 10.4 was introduced: a
pull-push mode.
Firmware and host can share tx queue state via
DMA. The state is logically a 2 dimensional array
addressed via peer_id+tid pair. Each entry is a
counter (either number of bytes or packets. Host
keeps it updated and firmware uses it for
scheduling Tx pull requests to host.
This allows MU-MIMO to become a lot more effective
with 10+ clients.

Firmware 10.4.3 onwards can support a pull-push Tx
model where it shares a Tx queue state with the
host.
The host updates the DMA region it pointed to
during HTT setup whenever number of software
queued from (on host) changes. Based on this
information firmware issues fetch requests to the
host telling the host how many frames from a list
of given stations/tids should be submitted to the
firmware.
The code won't be called because not all
appropriate HTT events are processed yet.

The pull-push functionality of 10.4 will be based
on peer_id and tid. These will need to be mapped,
eventually, to ieee80211_txq to be used with
ieee80211_tx_dequeue().
Iterating over existing stations every time
peer_id needs to be mapped to a station would be
inefficient wrt CPU time.
The new firmware, which will be the only user of
the code flow-wise, will guarantee to use low
peer_ids first so despite peer_map's apparent huge
size d-cache thrashing should not be a problem.
Older firmware hot paths will effectively not use
peer_map.

Tx pending counter logic assumed that the sk_buff
is already known and hence was performed in HTT
functions themselves.
However, for the sake of future wake_tx_queue()
usage the driver must be able to tell whether it
can submit more frames to firmware before it
dequeues frame from ieee80211_txq (and thus long
before HTT Tx functions are called) because once a
frame is dequeued it cannot be requeud back to
mac80211.
This prepares the driver for future changes.

Replace the local variable 'burst_enable' with 'param'
for mapping and setting pdev paraemeters and with this patch
pretty easy to extend support for new parameters adhering to
linux kernel coding guidelines

Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the
drv_ampdu_action() function, wrap them inside a structure.

Use SMPS disabled as default because FW does not indicate
any support of SMPS.
This change will help STAs out that don’t support SMPS from
sticking on 1SS, since they don’t have method to change it
back to multiple chains.
This change also should not affect power consumption of STAs
supporting SMPS, because they are capable to switch the mode
to dynamic or static either at the end of frame sequence or
by using SMPS action frame.

Mesh Point requires peer security key install when running
in secured mode since it's a type of peer links, otherwise peer
link will be removed due to key install failure.
MFP feature set is required to run Mesh in secured mode and
QCA988X firmware, 10.2.4.70.14-2 and above, is the only one
supporting secured Mesh at this moment.

QCA988X firmware starting from 10.2.4.70.12-2 has capability to support
Mesh Control Field Present bit in QoS field in native Wi-Fi mode.
Hence apply Mesh subtype according to the WMI service map.
Firmware will allows unicast, broadcast, multicast, and WDS frame
(FromDS = 1 and ToDS = 1) to be received via the interface, once Mesh
subtype is used.
The firmware and this patch together make native Wi-Fi mode comply to
IEEE802.11s Mesh frame in open mode, but the firmware doesn't yet
support secured Mesh mode.

Enable AP + STA interface combination support for 10.x and
this enables Repeater mode testing (with WDS Repeater combinations
as well). Fix indentation as well.
Based on the suggestions from Michal and Yanbo Li,
thanks to them
