Currently the driver calculates the nss score
based upon the max capability of the AP, and not the
hw_mde config which would be there after connection
for example, the driver calculates the score for a
2x2 11n AP, and 1x1 VHT (11ac) AP, it connects to the
11n AP in 1x1 mode, if a concurrent connection is
present, which affects throughput
Fix is to check whether the current AP channel results
in DBS or not, if yes then change the NSS to 1 instead of
2

However, there was an instance where the list traversal was done from

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)

Do null check before servicing the ring. When dp_service_srngs()
is common API which gets called when interrupt gets fired for
any ring. Within this API, driver goes one by one to each ring
and service the rings as it is not obvious from interrupt line that
which particular service ring needs to be served.
So race happens when rings are getting initialized and packet has been
arrived to one of the rings. Due to dp_service_srngs() API's
implementation, driver goes to one by one each ring without checking
if all rings are initialized.

The scheduler can run out of buffers and we panic
whenever this happens. However in the older code
we wait until the failure count of getting scheduler
buffers reaches a defined limit, thus making buffers
available in due time and the panic was seen in rare cases,
where failure count was exceeding the defined limit.
With the qdf_flex_mem supprt added for scheduler, the
wait to panic, when the failure count was removed and
we panic when the first failure to get scheduler buffer
is reached. This change adds to wait until the failure
count reaches the limit and then panic.
