qcacmn: API support for AST flow override

Browse Source 
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
