d555d146a4 qcacmn: add duplicate link desc check when refill
Same back to back link descriptor address/cookie is observed in
WBM idle link desc ring.
add duplicate link desc check when host
refill link descriptor to WBM through SW2WBM release ring,
also REO reinject ring.

9beeaa95a7 qcacmn: Add history to track the entries in rx rings
The rx rings are relatively of smaller size. Any
duplicate entry sent by hardware cannot be back-tracked
by just looking at the ring contents alone.

Hence add a history to track the entries for the
REO2SW, REO exception and SW2REO ring.

f3bffbfdd2 qcacmn: handle IPA buffer smmu map/unmap correctly
Handle ipa buffer smmu map/unmap with below changes,
(1) Do IPA smmu unmap for RX buffer received from REO
exception/WBM RX release/REO DST/RXDMA DST ring.
(2) Align IPA smmu map length to qdf_nbuf_map_nytes_single()
with fixed length.

8007762d6a qcacmn: Set invalid bit in cookie for exception ring descriptor
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.

Remove uncessary msdu count check against msdu count in

desc instead of mpdu desc info.
SOC level Rx err stat rx.err.msdu_count_mismatch is

909e4e1893 qcacmn: Keep rx_refill_buf_ring using index pdev->lmac_id under MCL case
Fix static analysis issue of rx_refill_buf_ring buffer overflow.
rx_refill_buf_ring length is different for WIN/MCL. For MCL length is 1,
WIN is 3. So rx_refill_buf_ring should always use index pdev->lmac_id to
replenish rx buffer for different MACs under MCL.

8156bbf7fd qcacmn: Add sg formation check
Add check for sg formation.
Only enable chfrag_cont and msdu_continuation if reo
error code is HAL_RX_WBM_ERR_SRC_REO or rxdma_err_code
is HAL_RXDMA_ERR_UNENCRYPTED.

Also chain all nbuf in case of sg in separate buffer
and finally loop through that. This is added because
sometime we dont get desc in sync with hw.
To avoid such mismatch, this buffer is added.
We will process nbuf only when all msdus has been
received.

two nbufs. Due to this, there is a mismatch between
msdu count fetched from MPDU desc detatils and count
fetched from rx link descriptor.

Fix is to create frag list for the case where msdu
is spread across multiple nbufs.

c064fc3b4a qcacmn: Reduce excessive console logging
There is excessive console logging in case of peer or vdev
null in mic error handling and wbm err processing in softirq
context which is delaying the interrupt to get enable and as a
result host is slow in reaping the wbm2sw3 ring. This leads to
wbm2sw3 ring full back pressure at FW and finally FW asserts.
As part of this change reduce reduce the error logging level from
err to info and for MSM info goes to the wifi logger logs and not
to the console.
