In following conditions RX LDPC support needs to be enabled
1) when STA is coming up in 5G band
2) when IBSS is coming up in 5G band
for anyother cases RX LDPC needs to be disabled. If user has
choosen RX LDPC to be disabled from INI file then it needs to
be disabled for all the cases including above mentioned cases.
To achieve this, take the intersection of global, INI, and harware
specific RX LDPC settings.

Make MAS (MCC Adaptive Scheduler) commands to be PDEV
specific.
Two instances of OCS (Off Channel Scheduler) can exist
in the FW (one per MAC) and FW provides the option of
enabling and disabling MAS on a per MAC basis. But,
Host does not have enable/disable option for individual
MACs. So, the agreement with the FW is for the Host to
send down a ‘pdev id’ of 0. When ‘pdev id’ of 0 is used,
FW treats this as a SOC level command and applies the
same value to both MACs. So, irrespective of the value
of ‘WMI_SERVICE_DEPRECATED_REPLACE’ in the WMI service
bit map, the pdev id needs to be ‘0’ (SOC level) for
the WMI command
WMI_RESMGR_ADAPTIVE_OCS_ENABLE_DISABLE_CMDID.
WMI command WMI_RESMGR_SET_CHAN_TIME_QUOTA_CMDID to set
the MCC quota is sent down as channel – value pairs.
The value being channel time quota and the channel being
sent down is a home channel. The additional requirement
from FW is that all the channels in a single WMI command
belong to the same MAC. FW asserts if the WMI command
mixes and matches home channels associated with
different MACs. So, although the PDEV ID is not part of
the WMI command struct, the cmd is in a sense PDEV
specific.
There is no change in the WMI command
WMI_RESMGR_SET_CHAN_LATENCY_CMDID to make it PDEV
specific since this WMI command always send only one
channel-latency pair to the FW. So, there shouldn’t be
any problem of FW receiving home channels associated
with different MACs, for this WMI command.

Add support for pre CAC on SAP for the user requested channel.
The reason for the requirement is to have SAP operations without
interruptions due to CAC. After starting SAP on the 2.4GHz
channel, the driver will start a pre CAC on the 5GHz DFS channel
requested. If no radar is detected, SAP is expected to switch
from the 2.4GHz channel to the DFS channel mentioned in the pre
CAC request. If radar is detected SAP will continue to operate on
the 2.4GHz channel. To provide the pre CAC channel to the driver,
vendor commands/attributes are used .

CONFIG_CNSS_LOGGER is introduced to move the logging feature from

This change will mainly benefit for two things for CLD driver.
- To support for dual wifi driver instances and also
future plan of moving out the logging thread and buffer
management to the kernel module.
- While debugging the critical feature that triggers the
autoshutdown and SSR, the log buffer in the CLD driver will
be lost after the driver restart or unload.
The CLD driver will register itself to the cnss logging module and
get the radio index as the indentification for rest of the operation.
Also the message sent from CLD driver to usespace need to be packed with
struct tAniNlHdr; and the hddctx.radio_index need to be filled along with
the message, so that usespace can differentiate the message.

Here is the brief description on the changes,
1) if STA came up first on DFS channel and SAP is coming up second
then as per concurrency rule SAP can't come up on DFS channel,
it can come up on 5G-non-dfs or 2G band.
2) if SAP came up first on DFS channel and STA is coming up second
then as per concurrency rule SAP has to move to non-dfs channel
by using channel switch announcement IE. Once SAP moves to
non-dfs channel then and then STA can continue on connection.
3) if there is any STA connection alive then SAP/GO's PCL shouldn't
contain any DFS channel in the list.
