In the case of WCN6450, WBM HW block is removed in the UMAC.
TX completions come via HTT messages. Add logic to handle
HTT TX completion messages from the firmware.
Changes are specific to WCN6450 and hence implement the logic
in the arch specific code.

The kernel-doc script identified a large number of documentation
issues in dp/wifi3.0/dp_tx.[ch], so fix those issues. In addition,
there are a number of instances where public functions have their
implementation documented instead of having their interface
documented, so move that documentation.

The following functions are currently public functions:
dp_tx_tso_cmn_desc_pool_alloc()
dp_tx_tso_cmn_desc_pool_init()
dp_tx_tso_cmn_desc_pool_deinit()
dp_tx_tso_cmn_desc_pool_free()
However these functions are only called from within the file where
they are defined, so make them static.

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.

Special frames like EAPOL should not be dropped as it would cause
failure in connection. To prevent the dropping of higher priority
special frames, reserve a set of descriptors from the tx descriptor
pool.
Check the regular soc or pdev limit for the allocating tx descriptors
for the regular packets and use the reserved set of descriptors
only for the special packets.

Suspect HW update WBM2SW ring HP, but the ring entry contents are
not updated accordingly which then host will fetch one stale ring entry,
this makes other TX packet are freed unexpectedlly.
Add change to detect this situation earlier, if HW cookie conversion is
done, then invalidate 2nd dword for upper 32bits of VA, so next time when
reap this ring entry contents to know if this desc is updated by
HW or not. if HW cookie conversion is not done, then compare the PA in
buff_addr_info with PA in current TX desc to check.

Currently HP update can skip for few packets if the system suspend
is happening in parallel with tx. This could lead to SMMU fault if
the skipped HP update goes after tx desc force free.
Remove the tx pause check in HP updates and have the check before
calling dp_tx_send in case of intra-bss forward case. No special
handling is needed for non intra-bss case as we don't expect packets
from network stack after suspend.

buffer_timestamp in wbm2sw ring descriptor is 19 bits only with
unit 1024 us, so it can only accommodate 0x7FFF * 1024 us same as
29 bits value with unit us. but if the timestamp value is >
0x7FFF * 1024 us, then the value stored in buffer_timestamp is not
right as other higher bits bit29 ~ bit31 is lost.
restore bit29 ~bit31 value for buffer_timestamp to fix current issue.

In case of MLO same adapter maps to both vdevs. Tx is done with
primary link vdev pool. In link switch case vdev0 flow pool is
deleted and traffic will continue to flow with same vdev0 flow_id
This is resulting in packets drops within the driver due non-availibilty
of flow pool.
Fix this by skipping flow pool deletion in case of STA MLO connection.

Currently the history recording for any debug purpose
is done using a contiguous memory chunk. For certain
history like tx_hw_ring, tx desc or tx completion desc
history, the amount of contiguous memory required is
very huge (order 7 or 8 allocation), which have a
higher probability of failing.
In order to mitigate the above scenario, introduce the
support for recording debug history into fragmented
chunks of memory, thereby reducing the requirement of
contiguous memory.
