Currently, in case of station+monitor mode on KIWI target,
we are not attempting to drop the entries received in the
monitor destination ring, when no channel has been
configured for the monitor interface. This leads to the
monitor destination ring full condition and an eventual
backpressure on the ring.
Fix this issue, by dropping the entries in the monitor
destination ring, which have been received before the
monitor channel has been configured.

When high throughput is running between AP and STA,
due to u8 variable overflow, host is not replenishing
required buffers.
More than 255 buffers can be requested for replenish,
so fixed size of the variable.

Currently the monitor mode processing assumes the
rx pkt tlv to be consisting of RX_PACKET_HEADER tlv.
This assumption is incorrect in case of sta+monitor
mode, where the RX_PACKET_HDR tlv has not been subscribed.
Due to the above incorrect assumption, a certain portion
of the actual payload is being discarded, when the
rx_pkt_hdr tlvs are stripped off from the received buffer.
To mitigate this issue, use the rx_pkt_tlv length based
on the tlvs which are enabled, and configured to the
rxdma for reception.

Currently the monitor mode filter settings are set
for both the PMAC. Hence it is possible that the
non-monitor PMAC (the PMAC on which monitor vdev
is not running), can receive packets and forward them
to the monitor destination ring.
The above scenario will lead to a ppdu_id mismatch
when reaping the monitor status ring and comparing
the ppdu_id in status ring with the one in monitor
destination ring, since monitor status ring will
have ppdu_id from the PMAC on which monitor vdev is
running, whereas monitor destination ring will have
packets from both the PMAC.
In order to mitigate the above issue, detect the
packets in the monitor destination ring, which are
not from the PMAC where monitor vdev is running, and
drop them.

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.
