Currently the code to support Multipass on SAP is
present along with the code to support WDS. Hence with
the code in its current state, we will not be able to
enable Multipass support without enabling WDS.
Move the multipass support code out of the WDS support
code, to be able to enable Multipass for chipsets which
do not use WDS.

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.

which is given to IPA, hence override the TX queue to 0 if

dp_tx_tso_cmn_desc_pool_free()

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.

for the regular packets and use the reserved set of descriptors
only for the special packets.

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.
