Dfs radar processing function dfs_process_radar_ind is called
in interrupt context. Add new API policy_mgr_get_can_skip_radar_event
to be called in interrupt context to get radar skip flag.
The policy_mgr_get_dfs_master_dynamic_enabled will acquire mutex and can't
be called in interrupt context.

Export wlan_reg_freq_width_to_chan_op_class_auto symbol
to be used in qca_ol module for retrieving opclass.
Change-Id: I44d9c424d66caf168d443f3542361deb9b3de300
The function reg_freq_width_to_chan_op_class calculates the channel
number and opclass to be filled in the ECSA IE. In this function,
there is a check if (op_class_tbl->start_freq + FREQ_TO_CHAN_SCALE
*op_class_tbl->channels[i] == freq)
In case of channel 14 in Japan opclass, since the start_freq =2407,
FREQ_TO_CHAN_SCALE=5 and channels[i] =14, this condition evaluates
to false and chan_num and opclass are not filled.
Fix this by setting the start_freq as 2414 as is done for the
global_op_class table.

crash scenario:
(1) during dp_vdev_detach_wifi3(), it will reset related outstanding
TX desc vdev pointer to NULL.
(2) In the meantime, if this vdev TX completion is received from HW,
dp_non_std_tx_comp_free_buff() do nothing for nbuf due to null vdev,
leak will happen.
add error handling in dp_non_std_tx_comp_free_buff() to fix it.

Add prefetch_timer configuration for CE rings.
Set prefetch_timer=1 configuration for qca6490 destination CEs,
prefetch_timer=0 configuration for other targets CEs.
Basically setting to 1us asking CE hw to update ring tail pointer to
update within 1us. FW side CE SW sets all rings to 1us already.
Idea behind this change is, we have seen pre-silicon issue where SRC
ring TP read by SW was not seen updated value when prefetch was set
to 8us. Changing prefetch timer value to 1us helps to resolve
pre-silicon issue.
So host side rings need to update the prefetch timer to 1us.

In OOR error handling scenario, msdu is spread across
two nbufs. Due to this, there is a mismatch between
msdu count fetched from MPDU desc detatils and count
fetched from rx link descriptor.
Fix is to create frag list for the case where msdu
is spread across multiple nbufs.

An extension of preCAC feature is Rolling CAC. The distinct difference
between these features is that the FW runs the off channel CAC
timer for a "finite" time for preCAC and runs the timer for "infinite"
time on an off channel. Hence the infrastructure built for
preCAC feature is being modified to accommodate RCAC feature as well.
Following are the modifications done:
1. Add an enum to represent various off-channel CAC modes.
2. Remove the 'static' declaration of few APIS so as to re-use them.
3. Add 'dfs_rcac_ch_params' to DFS PDEV object to store the RCAC
channel params so as to use the channel params after radar detect.
4. Rename DFS APIs to match its functionality.

The roam sequence in LFR-3.0 is roam scan start notification
from firmware followed by roam start indication and then
roam synch,roam synch frame events. Roam start is sent
after candidate selection and host driver will disable
queues when roam start is received.
But for emergency roam trigger, firmware sends roam start
indication directly without notifying roam scan start to disable
data path queues immediately after deauth received from the AP.
So roam start is received before roam scan is started at firmware
and before candidate selection is done.
After roam start notification, host sends scan abort for all scan
on vdev by setting scan command request type to
WMI_SCN_STOP_VAP_ALL. This results in roam scan getting aborted at
firmare in emergency deauth roaming case and roaming fails.
Introduce new vdev id value based on which the scan module will
abort only host triggered scans setting the flag
WMI_SCN_STOP_HOST_VAP_ALL in the scan request.

During initialization of driver, the runtime pm usage
count is incremented to 1 when the pm state is NONE.
Runtime get is done as part of htc send packet for
a wmi command in scheduler thread context. In kworker,
runtime_start is processed as part of driver load and
runtime put is done prior to updating the pm state to
ON. Runtime put triggered as part of htc send packet
causes a panic since the state is NONE and usage
count is 1.
Fix is to set runtime pm state to ON prior to doing
a runtime put as part of initialization.

The delayed register write enqueue fills a queue element
with the required data which can be dequeued in a workqueue
running on a different CPU. Since these operations are not
lock protected, there can be stale value access when memory
write has not been flushed to the actual address.
Using write memory barrier before setting the valid flag for
a queue element will make sure that the dequeuing worker
thread will always see the updated values if the element valid
flag is set and thereby avoid any race condition.

As a part of vdev responses from the FW, the driver fetches the
appropriate vdev_response_timer info using the vdev_id. This vdev_id is
taken from the response coming from FW. Currently, this vdev_id is not
being validated and is being used to access the array psoc_vdev_rt. This
can potentially lead to out of bounds access.

1) Modified MSI interrupt mask for QCN9000 so that rx and tx
interrupts can be decoupled.
2) Removed lmac interrupts from polling mode and switched
them to msi interrupts. Added MSI masks for lmac rings.
3) Enable monitor mode LWM interrupt. This was already enabled in
integrated ahb interrupts but missing in msi. Replenish buffers in
RXDMA refill ring based on low threshold interrupts in addition to
regular Rx processing. Also made interrupt batch counter threshold as 8
for monitor status ring since ppdu end interrupts are not available in
PCI chipset and require srng msi interrupts to reap monitor status ring

In current monitor status ring implementation,
on pdev_attach, (srng->num_entires – 1) entries
(to keep one entry slot between hp and tp)
are replenished and last entry is not replenished to HW.
With qcn9000 monitor mode HW enhancements, status and destination ring
can be made lock-stepped.
for qcn9000 lock step is achieved by making monitor status ring
follow the monitor destination reap for a PPDU
However in existing flow during attach monitor status replenish logic
do not fill last entry but is filled up during first subsequent reap.
for first ppdu, i.e. after reaping destination ring,
when status ring is reaped, as first entry (hp = srng->num_entires – 1)
in status ring is NULL, so lock-stepping is not achieved.
To address this issue for qcn9000 as well as HK:
a. Replenish last entry in monitor status ring during attach
b. Modify src srng peek API to peek it from hp+1 entry
c. Introduce new HAL API get cur desc and move next
d. Remove WAR to skip status ring entries if DMA is not done
