Add enum QDF_MCC_TO_SCC_WITH_PREFERRED_BAND(6) for this.
If ini gWlanMccToSccSwitchMode is selected to
QDF_MCC_TO_SCC_WITH_PREFERRED_BAND(6) then following will be the
behaviour of STA+SAP concurrency.
1. If second interface(SAP/STA) comes in same band as
first interface(STA/SAP) respectively then force SCC
irrespective of channel.
2. If second interface(SAP/STA) comes in other band as
first interface(STA/SAP) then dont force SCC allow
interband MCC or DBS based on DBS capability.
Allow interband MCC but not intraband MCC.

kcompactd consumes many CPU cycles without being successful
to make high-order page. One of the reason is WIFI driver is
allocating order-3 page a lot.
It shows 46% high-order allocation comes from WIFI driver.
Of course, it should be fixed in MM layer but it is never
easy stuff to fix in near future.
Regardless of MM changes, drivers should do best effort to reduce
high-order allocation, too.
This patch fixes the problem via not waking kcompactd.

In case where a qdf event was waiting and an SSR has occurred,
force_set flag is set for the event. After driver recovery is
complete the same event can be reset and re-used without
resetting this flag. This may cause a failure even after the
event was successfully completed.
Clear the force_set flag while resetting a qdf_event

As WIN has multiple modules and QDF is the last one to be unloaded,
QDF is crashing when it tried to print the file name of an nbuf
allocated by other modules. To fix this, copy the file name in the
QDF nbuf tracker, rather than using the pointer to file name,
to avoid access to the invalid pointer.

Netlink service init and exit is invoked as part of wlan logging
init and exit during qdf module init and exit. This brings in a
hard dependency to enable and compile wlan logging service
even if not used.
Decouple netlink service and wlan logging service to remove
inter-dependency. WIN qdf module currently does not require wlan
logging to be enabled. This separation leads to bss savings in qdf
module.

Previously legacy definitions tQDF_GLOBAL_CON_MODE and
tQDF_ADAPTER_MODE were renamed to have converged semantics. However
since these were defined in a common project, and since not all
references could be simultaneously changed, legacy definitions were
left with the expectation that they would be removed when all
references to the legacy definitions had been updated.
All of the legacy references have now been updated, so remove the
legacy definitions.

Currently, the scheduler thread keeps a large, pre-allocated array of
messages for use in message posting. The vast majority of the time,
however, the scheduler thread has zero or one messages pending in the
queue. This leads to a huge memory overhead for nominal driver
operation.
Replace the current pre-allocated scheduler message pool with a
hybrid static/dynamic approach.

nbuf map tracking requires a bit of metadata which is currently
allocated dynamically for each mapping request. Change these allocations
