From: Thiraviyam Mariyappan <quic_tmariyap@xxxxxxxxxxx>
Currently, TCL performs the TX address search for each entry during
transmission, which may lead to packet delays.
To mitigate this issue, enable AST index-based address search during
transmission in station mode. This AST index-based search is not
enabled in AP mode due to the complexity involved in fetching peer
information.
Implement changes to retrieve the offset of ast_idx/ast_hash values
from the PEER_MAP3 event, update the vdev search type to ADDRX, and
enable AST lookup in the bank configuration.
