was brought in to fix a race condition between Rx buffers
map/unmapped in dp_ipa_handle_rx_buf_smmu_mapping() and at the
same time map/unmapped from dp rx replenish context.
The fix ensured that rx_desc is unmapped and rx_desc->unmapped=1
flag will be set atomically within a lock.
But Change-Id: Iadb40071fb733cc4de3291784df5075d5a099a8e
introduced a flaw by releasing the lock before setting the flag to 1.
This is currently causing race condition and causing double
unmap calls when IPA smmu pool unmap and dp_rx_replenish unmap
is running in parallel. This change will fix this issue, by setting
the flag before the lock is released.

In the LPM case, if the tx desc has been force
freed in the dp_bus_suspend ->dp_find_missing_tx_comp,
then after data transfer resumed, fw may report
tx complete for the same tx desc, and we should
skip it to avoid null pointer access.
The reason why set default vdev_id to 0xff is:
Since in this case, it happned disconnect before
suspend, so the tx desc pool will be deleted and
reinitalized when resume, so the pdev is null in
the force freed tx_desc and vdev_id should be changed
from 0 to DP_INVALID_VDEV_ID, otherwise the below logic
in the tx complete handler will not skip handling
this freed tx_desc.
if (qdf_unlikely((tx_desc->vdev_id == DP_INVALID_VDEV_ID) &&
!tx_desc->flags)) {
DP_STATS_INC(soc, tx.tx_comp_exception,1);
dp_tx_desc_check_corruption(tx_desc);
continue;

done the following changes to improve the RX path KPI
1. remove the extra invalidate in RX path as
we no longer dirty the RX TLV cache lines.
we now store the rx error codes in nbuf cb instead
of RX TLVs reserved memory bytes.
2. with features like flow tag and wds extended mode
enabled by default, the rx_fast_flag is always set
to false, this resulted in lot more instructions
being executed in RX path.
Now we ensured this flag is at least set for other
features which are not enabled by default.

Currently dp_soc_init/deinit API's are called first for
common soc initialization/deinitialization and then architecture
level init/deinit APIs are called from base dp_soc_init/deinit.
But with RHINE architecture dp_soc_init/deinit API's are not common,
so we cannot call these APIs as base. To handle this scenario
routing all the soc level init/deinit from arch ops APIs and
arch ops APIs will take care of calling common soc_init/deinit.

Remove wapi frames from is_eapol check in dp_rx_null_q_desc.
This change is to address the below issue:
First wapi packet received in dp_rx_nll_q_desc,
before TID setup does not reach stack since it is
treated as an eapol frame and gets dropped in
dp_rx_eapol_deliver_to_stack.

WCN6450 is a chip based on Rhine architecture. Unlike LI/BE targets,
chipsets based on Rhine (RH) do not have host facing UMAC HW blocks.
Their corresponding SRNG interfaces are also removed. The functionality
of these UMAC HW blocks is replaced with a software implementation in
the firmware. Communication between the driver and firmware will happen
over copy engine (CE).
Although there are no host facing UMAC HW blocks, the CE hardware used
in WCN6450 expects the host driver to use the TX descriptor (HW) format
of LI targets during TX packet enqueue. Therefore it is required to
create a new pool of TX descriptors (HW) pool for WCN6450 that is used
during TX.
The logic to create/free/init/deinit these descriptors is specific
to WCN6450/Rhine, therefore it is implemented in architecture specific
Rhine code.
Introduce new APIs in struct dp_arch_ops {} to allocate and free
arch specific TX descriptors. These ops will be no-op for LI/BE
architectures.
Also for Rhine targets, allocate/free other TX descriptors like TX EXT &
TSO descriptors as part of the arch APIs.

In case of where multiple scatter gather frames are
part of same MPDU last_mpdu_in_msdu will be set only
for last buffer of last scatter frame in MPDU.
Below is the hw descriptors bits when 2 scatter frames
are part of a MPDU
-----------------------------------------------------------
|Buffer_num | MSDU_NUM | first_in_mpdu | cont | last_in_mpdu |
-----------------------------------------------------------
| 1 | 1 | 1 | 1 | 0 |
-----------------------------------------------------------
| 2 | 1 | 0 | 0 | 0 |
-----------------------------------------------------------
| 3 | 2 | 0 | 1 | 0 |
-----------------------------------------------------------
| 4 | 2 | 0 | 0 | 1 |
-----------------------------------------------------------
In above case scatter MSDU boundary checks can be done only
based on continuation bit. So while reaping use continuation
bit instead of last_in_mpdu bit to detect boundary

Currently HTT_TX_FW2WBM_TX_STATUS_DROP and HTT_TX_FW2WBM_TX_STATUS_TTL
are mapped to HAL_TX_TQM_RR_REM_CMD_REM which results in the wrong Tx
status print in case HTT_TX_FW2WBM_TX_STATUS_TTL where No ack is received.
So to fix the status log issue map HTT_TX_FW2WBM_TX_STATUS_DROP to
HAL_TX_TQM_RR_REM_CMD_REM and HTT_TX_FW2WBM_TX_STATUS_TTL to
HAL_TX_TQM_RR_REM_CMD_TX to log correct Tx Fail Status.
