In roam HO failure, peer unmap indication is processed
even before Host initiates the peer cleanup. In the cleanup,
as part of cdp_peer_teardown, AST entries are freed up without
removing it from the peer AST list since get_peer_by_ref_id
returns NULL peer pointer as peer is moved to inactive state.
Fix is to delete peer AST entries as part of peer unmap
indication so that the entries are removed from the AST list.

Add new APIs to iterate through the vdev peer list
by taking the peer reference.
A call back has to be passed to these APIs which will
be called for every peer in the lisst
dp_vdev_iterate_peer() -> iterates through peer_list of vdev
dp_pdev_iterate_peer() -> iterates through peer_list of all
vdevs in pdev
dp_soc_iterate_peer() -> iterates through peer_lists of all vdevs
in soc
Additonal APIs are added to for itearations where the callback
will be called outside the vdev->peer_list_lock, as these APIs
have additional memory allocations suggested to use only in case
the iteration need to happen outside lock
dp_vdev_iterate_peer_lock_safe()
dp_pdev_iterate_peer_lock_safe()
dp_soc_iterate_peer_lock_safe

The peer rx packets should be flushed when
deleting the peer and its state should be reset
to DISCONNECT, when deleting the peer.
If the state of peer is not set to DISCONNECT,
then the flushing of rx packets for the peer
which is being deleted will call the rx callback
and submit these packet to the stack, which can
cause unwanted behaviour.
This way the UMAC does not need to specifically
call clear peer before deleting the peer.

Lithium HW can parse each MSDU when packets are enqueued to transmit
classifier and each MSDU can get enqueued to different MSDU-Queue.
By default, there are 2 queues per TID – UDP and NON-UDP. Based on
the flow parsing, packets will be queued to either of them.
Enterprise customers uses RAW mode frames which transmit classifier
would not be able to identify L4 protocol for UDP or NON-UDP queue
for encrypted frames.
Customer can also have different application based packets which needs
to be enqueued to differently prioritized queues. They can choose to
tag each MSDU based on application DPI and derive the flow priority
as below –
• UDP
• NON-UDP
• HI-PRIO
• LOW-PRIO
Customer needs API support from host which will provide an ast-index
based on a particular flow id given peer mac address. Based on the mac
address, host will find the associated peer and return the ast_index &
cache set number corresponding to the flow id from peer flow based ast
entry table. Customer will then program this ast-index and ast override
in transmit classifier CMD ring to enqueue MSDU to a specific
flow-queuein TQM.
Host API:
Input parameter – uint8_t *peer mac address, uint8_t flow id
Output – uint16_t ast_index

Memory leak fixed in dp_rx_tid_delete_wifi3 in the case
where update cmd send fails. Add the desc to the front of
free desc list and set a flag to ensure that the update
cmd is resent from delete rx_tid callback. In the same
callback ensure that the update cmd desc is sent out first
and then proceed to free other descs by sending out the
flush cache cmd for each of those descs.
If the flush cache cmd is not sent successfully to REO,
add the REO descriptor back to the free desc list and
defer the deletion to the callback function. This update
is made under MCL feature flag REO_DESC_DEFER_FREE.
Add a soc level stat to indicate the reo send cmd failures.
