5379474f69 qcacmn: Enabled asserts in Rx error path
Enable qdf_assert on rx error path to detect corruption issues.
Also add a magic word in rx_desc and compare on rx indications
to detect any corruption issues early in the path

6eca1a62da qcacmn: Monitor mode configuration and processing
This change is for supporting monitor mode VAP.  All the monitor mode ring
is configured. The related monitor mode ring includes:
-monitor mode buffer ring
-monitor mode destination ring
-monitor mode status ring
-monitor mode link descriptor ring
The packet is not sent to monitor mode ring unless the monitor mode VAP is
configured. This release support Multiple VAP - AP/STA VAP plus Monitor
VAP configuration. The status ring is not used in this release. However,
the ring is tested and the ring is moving and there are TLV's in the ring.

5dba3a3f9a qcacmn: Fix init failure and DP detach crash
Skip free of nbuf with physical address less than 0x50000000. This will
ensure that same buffer is not getting allocated again resulting longer
DP init time and affecting WMI init sequence. And use correct pointer
in pdev detach function.

4e3341aa2a qcacmn: RX nbuf allocation from phy addr 0x50000000 and above for x86
We should always ensure memory allocation for rx nbufs
should always happen from phy address 0x50000000 and above
else drop the nbuf and try for a new nbuf.

603c594e45 qcacmn: DP RX optimization changes
Added a separate loop to dequeue the rx pkts and relinquish
REO and rx-Refill ring faster. Additionl rx processing is
moved to a different per vdev loop.

1ef5480ea4 qcacmn: Added support to handle NULL Q descriptors
The MC BC packets cause a NULL REO queue descriptor exception,
and hence are directed to the ring that is configured to receive
this exception from REO. As of now, this error is directed to
WBM release ring. Add handling to pass these packets to stack
instead of dropping them, when received on the WBM release ring.

Note that, the final fix may be route these to REO exception ring
from which the driver may need to pass them to stack.

c4c52dc1fd qcacmn: Add Lithium RX Core Processing Infrastructure
Add Lithium Rx basic packet processing path from REO.
Implement the following in this patch:

 - Rx buffer replenishment directly to RxDMA rings (WIN)

 - Rx descriptor management

 - Rx Path Processing for non-error packets

 - RxDMA optimization (access on 128 byte boundary)
