Spectral HW time stamp gets reset when a reset happens in
within target. This can potentially result in unpredictable
behaviour during classification. To mitigate this calculated
offset is added to the time stamp value in the FFT report.
HT = Spectral HW timer
AT = Actual time stamp in spectral report
CF = Time stamp correction factor
CT = Corrected time stamp
L = Time stamp in the last FFT report before reset
F = Time stamp in the first FFT report after reset
D = Time gap between the last spectral report before reset
and the end of reset(This is provided by FW via direct
DMA framework)

HT --> 0 L 0 F
AT --> 0 L F
CF --> 0 0 (L+D)
CT --> 0 L (F+L+D)
Spectral driver corrects the time stamp received from target
using the following formula and sends upwards.
CT(Corrected time stamp) = AT(Actual time stamp) +
CF(Correction Factor)
Calculation of Correction factor (CF):-
---------------------------------------
Initialization : CF = 0
CF += (L + D) (Done only for the first spectral report after reset)
This scheme takes care of the wrap around in the 32 bit time stamp
which would have occurred if the timer was not restarted due to
target reset.

In the existing converged component, WMI TLV APIs are implemented in
a generic manner without proper featurization. All the APIs exposed
outside of WMI are implemented in wmi_unified_api.c and all the APIs
forming the CMD or extracting the EVT is implemented in wmi_unified_tlv.c.
Since WIN and MCL have a unified WMI layer in the converged component and
there are features within WIN and MCL that are not common, there exists a
good number of WMI APIs which are specific to WIN but compiled by MCL and
vice-versa. Due to this inadvertent problem, there is a chunk of code and
memory used up by WIN and MCL for features that are not used in their
products.
Featurize WMI APIs and TLVs that are specific to WIN
- Air Time Fareness (ATF)
- Direct Buffer Rx (DBR)
- Smart Antenna (SMART_ANT)
- Generic WIN specific WMI (AP)
