The net buf tracking feature spend most of its time allocating
tracking cookies. By not tracking these tracking cookies in
qdf we achieve a 90% time saving. By keeping a freelist and
avoiding allocations altoogether, we save another 90%. This
feature is 99% cheaper. Throughput suffers less under when
the driver is forced to be cpu bound (eg. by mucking with the clockspeed).

Initially, the QCA Wi-Fi driver was ported to support kernel
4.4. However, after the code changes due to converged code,
few issues were re-created when compiled on kernel 4.4.X.
This change resolves the newly introduced issues by the
converged code changes.

At a cost of keeping 1023 more spinlocks in memory, we can avoid
spinlock contention between different hash keys while performing
the lookup.

Improve hash function to better utilize the memory entropy.
Do memory allocation outside of the spinlock.

error bus type.

Issues are seen where memory allocation takes 300-1000ms.
So to detect this reduce the QDF_GET_MEMORY_TIME_THRESHOLD value
to print the time taken by kmalloc, to 300ms from 3 sec.

Add target bus type field in qdf context, as bus type
needs to accessed at multiple layer.

Do not update physical address in control block while
nbuf push/pull operation for WIN.
Also uncomment dma_sync_single_for_cpu function in
__qdf_nbuf_sync_single_for_cpu.

In case of DFS channels and EBT is disabled, beacons are
forwarded to host in every 50msecs which increase power consumption.
Add the changes to set beacon filter once DUT connect to AP.

Do following cleanup on fastpath code changes:
1) Do not reap off Tx HIF buffers in Rx handling, instead handle
reaping in Tx fastpath itself.
2) In ce_per_engine_service_fast check for more Rx packets after
packet processing.
3) Make stub functions as static inline for non-fastpath enabled case.
