If frames from the same FISA flow goes into different REO2SW rings, it
will result in an unexpected FISA behavior. This can happen if the
frames have been reinjected from FW offload module since FW will select
REO2SW1 ring. If the same flow frames hash to other REO2SW rings, then
the same flow UDP frames will do to different rings.
Reo_destination_indication of 6 indicates if the frame has been
reinjected from FW. If so, then continue to deliver the packet without
FISA.

MSDU count is not reliable in all cases.Hence it is better
to check whether next_link_desc is valid or not and then
free the MSDUs in the next descriptor and subsequently
release both the current and next link descriptor back to HW.

In monitor mode, radiotap header contains VHT/HE information in management
and control frames after association of STA to AP.For this,reset of
ppdu_info is required before processing of ppdu in order to avoid reuse

On returning the msdu link descriptor to HW via WBM
release ring, the rx exception ring contents are not
zeroed. This could result in host reading stale ring
descriptor content in the scenario when HP is updated
even before the latest values are reflected in the ring
descriptor.
Fix is to set invalid bit in cookie for exception ring
descriptor and add cookie sanity check.

Currently all the rx ring descriptor contents are left
intact even after these entries are processed. This can,
at times, lead to stale entries being processed, if the
head pointer of any ring is updated before the updated
contents of the ring descriptor gets reflected in the memory.
This can lead to scenarios where the host driver reads a
stale value of sw_cookie, and free/unmap a currently in-use
buffer, thereby leading to the hardware accessing unmapped
memory region.
The sw_cookie is the integral part of al the rx ring
processing. Hence we always mark the sw_cookie as invalid
after dequeuing an entry from the REO2SW ring. Every time
we check for the validity of the sw_cookie before we try to
process an entry from REO2SW ring. if the invalid bit in the
sw_cookie is set, we just skip this entry and move on to the
next entry in the ring.

a. Use hal_rx_hw_desc_get_ppduid_get () -
to get ppdu id from rx_tlv_hdr or hw descriptor based on target.
for qcn9000, this API gets ppdu_id from HW descriptor,
