In case of low memory, it could be difficult to allocate luts at
once. So, allocate lut based on number of DBR entry and
split memory allocation.

1. MAC does not really consider the expect TA and the
expect RA when the expect TA mask and expect RA mask is 0.
Basically, it checks for the subtype, bandwidth and NSS
as the filter criteria.
2. In the other scenario, if the RA matches with expect
RA and TA matches with expect TA then it does not really
consider the expect TA MASK and expect RA MASK.
With the current default config, since the expect address
mask is 00:00:00:00:00:00 it falls under case 1 and it is
written based on the MAC recipe.
But actual MAC logic is different from what is mentioned
in the recipe. MAC works on below logic:
TA & TA MASK = Expect TA & expect TA mask
RA & RA MASK = Expect RA & expect RA mask
As an additional precaution, we need to modify default
subtype as 0 so that if user enables any group by mistake
and does not give any input for the other RCC
configurations, we can block the RCC to capture CFR data.

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.

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

2. Add counters to track the total no. of TX-based CFR captures since
wifi up.

37th bit is being set as an exchange between FW and ucode
to indicate that it is a DDR address to PCSS module.
As a result of which Cookie lookup fails while comparing
all 40 bits, since the physical address of DBR buffer
does not match with the physical address of the received
buffer.
Since lower 36bits represents physical address,
Use only 4 least significant bits from higher 32bits along
with lower 32 bits while programming the physical address in
DBR SRNG. Format: ( low32 + 4 bits of high32 ).

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.

PHY may not be able to capture the CFR data in certain cases.
Ucode will update the reason due to which CFR capture did not
happen in PHYRX_PKT_END TLV.
Channel capture status -
0 - CAPTURE_IDLE
1 - CAPTURE_BUSY
2 - CAPTURE_ACTIVE
3 - CAPTURE_NO_BUFFER
Originally, ucode updated channel capture status only for PPDUs,
for which PHY was able to capture CFR data successfully. Ucode is
making a change to report channel capture status in PPDUs for which
PHY was unable to capture CFR data.
Re-positioning the counters in host to handle this new change in
ucode.
