From: Sriram R <quic_srirrama@xxxxxxxxxxx>
Currently in function mlme_event_mgmt_tx_status(), link_id will be only
filled if the frame was the last transmitted on the whole drv (driver)
level. With co-hosted MLDs, there could be cases where multiple packets
are sent out by various interfaces (BSS) under the same drv. Now while
handling the Tx status, only one interface will get the proper link_id.
Rest all will get -1, and event will be routed to first BSS always. If the
packet was not sent from first BSS then this leads to possibility of packet
getting dropped.
Hence in order to make the underlying link identification easier, modify
authentication and association frames to be always sent with link address
as A1 and A3 for ease of Tx status handling.
