Check the return status of the osif->rx function and in case
of failure drop the skb. This is needed when OOR error frame
is received and if the frame was not delivered to stack it
needs to be dropped.
Add error counter to periodic stats to determine how many Rx
packets were rejected or were dropped since deliver to
stack failed.
Add the new status check for delivering rx frames to stack
under MCC specific flag - DELIVERY_TO_STACK_STATUS_CHECK.

Fix the skb leak in dp_rx_process where rx descriptor cookie
validity fails. This skb should be cleaned up as part of the

However this will ensure that the skb released and added rx desc

Add skb map, unmap functions, line numbers and if the nbuf is
mapped or unmapped to the nbuf tracking table. This debug info

interrupts can be decoupled.
2) Removed lmac interrupts from polling mode and switched

3) Enable monitor mode LWM interrupt. This was already enabled in
integrated ahb interrupts but missing in msi. Replenish buffers in
RXDMA refill ring based on low threshold interrupts in addition to
regular Rx processing. Also made interrupt batch counter threshold as 8
for monitor status ring since ppdu end interrupts are not available in
PCI chipset and require srng msi interrupts to reap monitor status ring

In current monitor status ring implementation,
on pdev_attach, (srng->num_entires – 1) entries
(to keep one entry slot between hp and tp)
are replenished and last entry is not replenished to HW.
With qcn9000 monitor mode HW enhancements, status and destination ring
can be made lock-stepped.
for qcn9000 lock step is achieved by making monitor status ring
follow the monitor destination reap for a PPDU
However in existing flow during attach monitor status replenish logic
do not fill last entry but is filled up during first subsequent reap.
for first ppdu, i.e. after reaping destination ring,
when status ring is reaped, as first entry (hp = srng->num_entires – 1)
in status ring is NULL, so lock-stepping is not achieved.
To address this issue for qcn9000 as well as HK:
a. Replenish last entry in monitor status ring during attach
b. Modify src srng peek API to peek it from hp+1 entry
c. Introduce new HAL API get cur desc and move next
d. Remove WAR to skip status ring entries if DMA is not done

The peer rx packets should be flushed when
deleting the peer and its state should be reset
to DISCONNECT, when deleting the peer.
If the state of peer is not set to DISCONNECT,
then the flushing of rx packets for the peer
which is being deleted will call the rx callback
and submit these packet to the stack, which can
cause unwanted behaviour.
This way the UMAC does not need to specifically
call clear peer before deleting the peer.
