When the length of a 802.11 frame is more than the
size of the posted receive buffers, it is split across
multiple buffers, which have to be accumulated before
submitting to network stack.
For all-but-last buffer which are used for the above
mentioned large 802.11 frame, the MSDU_CONTINUATION
flag will be set indicating that remaining data of the
same msdu has been DMA'ed to the next buffer.
The current implementation in monitor-1.0 works for
legacy chipsets, where MSDU_START tlv is available and
hence the aforementioned information was available in
all the buffers containing the large 802.11 frame.
For kiwi target, there is no MSDU_START tlv, and hence
a lot of information eg: mpdu_len_err, decap_format and
l2_hdr_offset are not available in the buffers where the
msdu_continuation flag is set. This leads to an attempt
of mpdu_restitch using incorrect data from tlv, and hence
the mpdu_restitch fails for such large 802.11 frame.
Fix this issue for kiwi target, by gathering all these
information which are available in the last buffer and
are used to process/accumulate the entire 802.11 frame.

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.

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.
