207111647e qcacmn: Validate rx desc unmap in RXDMA err ring
Currently, in STA+Monitor mode, the first MSDU in MPDU is
unmapped and goes down. This MSDU is now processed as rxdma
err packet and crashes due to double unmap as rxdma err ring
is configured as monitor dest ring in monitor mode.
To fix this, validate rx descriptor unmapped flag in rxdma
err processing.

42dd66b280 qcacmn: Allow all OOR frames to deliver to stack
Few APs are sending bar frame right after sending a
packet but the packet is not received and its retry
is received with the same sequence number. As SSN
is moved ahead due to bar frame, this packet is being
dropped.
To fix this, allow all frames to get delivered to stack.

21f6f3ad8f qcacmn: Donot do PN-Check for open mode OOR frames
Currently pn-check logic for OOR frames does not take into account
the security mode. For open mode case, BE hardware does not populate
current and previous pn_numbers. Hence a PN-check comparison may yield
incorrect results.

Check for secure mode, before checking for PN numbers.

af17c944fb qcacmn: Rx stats changes for BE HW vdev stats
Following peer stats are updated in per packet Rx path:
    to_stack
    multicast
    broadcast

In BE architecture, HW provides the support for basic vdev stats and
hence per packet stats updation of above parameters can be done only
when enhanced stats is enabled or HW vdev offload stats is disabled.

Avoiding per packet stats updation reduces CPU load and improves KPI.
