FW may limit the interval and duration during which HW may
use user provided values and attempt to capture.
These values range from 1 us to roughly 16.8 sec.
Max value is 0xFFFFFF which is 16.777215 sec.
Add check to make sure that capture duration cannot exceed
capture interval.

Protect access to cfr lookup table, since error handling
mechanism attempts to cleanup CFR entries in timer context,
this leads to contention between bottom-half and timer.

RCC specific debug counters has been moved to DP layer.
Update capture BW from RXTLV instead of VDEV
Capture BW is the bandwidth at which Station operates.
Error handling for pdev referencce count.
Add support to clear CFR ppdu counters
Use same event ENUM for HKV2 and Cypress.

1. Change the default values of TA\RA entries
Host sends out one default RCC setting to FW during
the initialization of target specific CFR component.
Change the default setting of TA, RA address from
00:00:00:00:00:00 to FF:FF:FF:FF:FF:FF and TA_MASK and RA_MASK
should be 00:00:00:00:00:00. This will avoid
the scenario where the system will allow all packets
irrespective of the filter settings provided by the user.
2. In case default configuration is being sent to the FW
successfully during CFR init, those configurations will
be updated as part of global config. So that it can be
reflected as part of rcc_config_details command.
3. Code clean up
Change-Id: I719ddeee48f14992b2210562596b1ea3d61fcc1c
A new flag "is_cfr_rcc_capable", is introduced to enable RCC.
Currently, this flag is enabled only for QCA6018.

Add counters for following scenarios -
1. Ucode aborts DMA of CFR data when a higher priority TX/RX activity
needs to be scheduled, add counters in host to identify the no. of
aborts.
2. Add counters to track the total no. of TX-based CFR captures since
wifi up.

1. Remove the handler that flushes all pending DBR and txrx
events, since that is not being used.
2. PPDU TLV subscribe logic is integrated with ol stats layer,
remove redundant subscriber alloc.
3. Downgrade debug level of timer prints, as error handling timer
fires every 3 secs.

In CFR error handling lut ageout timer, following fixes are made -
1. Fire error handling timer every 3 secs
2. Start/Stop timer only when pdev->cfr_rcc_mode transitions from enable
to disable and vice versa
3. Stop/Free timer during deinit of pdev, incase user issues wifi down
without disabling cfr

Do not flush the DBR event for which the corresponding
TX/RX event is yet to be received.
Once the new PPDU TLV is received, flush the previous
pending DBR events.

1. In CFR RCC mode, when ucode aborts DMA of CFR data, 2 (or)
more PPDU status TLVs are likely to have same phy_addr+cookie in
RX location TLV, so the host will be flushing out the older PPDU
status TLV events instead of DBR events in LUT table,
since DBR events signify the actual DMA completion.
2. Same fix has been made for LUT entry ageout logic.

Channel Frequency Response(CFR) captures FFT bins corresponding to a PPDU
received and this is relayed to user space application along with
additional information about the PPDU gathered in the host. Usecases of
this feature include location sensing, motion detection.
