Currently SW writes a magic number in the tx completion
ring descriptor after reaping from the ring. This magic
number is used to determine, if the HP of the srng has been
updated without the contents of the ring descriptor has been
written.
There were cases of such stale entries observed and as a SW
workaround, add a logic to wait for a specific timeout for
the contents of the ring descriptor to be updated before
moving on to process subsequent ring entries.

Optimize tx completion processing in fastpath by adding the list of
tx descs to the free list directly instead of individually accessing
each descriptor and adding it to free list. This gives advantages of
not taking descriptor pool lock for each descriptor and rather takes
the lock only once when appending the whole list of descs to the
free list.
Also removed unused member shinfo_addr from tx_desc structure. Removal
of this member enables increase of flags type from u16 to u32 without
increasing the size of tx_desc structure. These changes improved peak
KPI by 2% in SFE mode.

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.

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.

Currently, we record TX musdu number and packet length, which falls into
three categories: from stack, from host and successfully transmitted. In
TSO mode, the msdu from stack will be divided into several fragments and
each of the fragment will be transmitted as an individual msdu. This change
will take TSO into account when it comes to the 3 forms of TX statstics.

bank id is newly added in TX descriptor for BE chipsets. As such,
with IPA Offload enabled, IPA needs the bank id information to do
offload WLAN TX.
From WLAN perspective, bank id is designed to be used on a per-vdev
role basis. E.g. STA vdev and SAP vdev have separate and different
bank profiles.
However from IPA perspective, bank id needs to be on a per TX ring
basis, because IPA GSI FW is not able to identify STA or SAP vdev
role on a per-packet basis.
Hence initialize last HOST owned bank id profile for IPA usage.
