From: Shivani Baranwal <quic_shivbara@xxxxxxxxxxx>
This commit does below
- Allow driver's SME to enable MLO(Multi-Link Operation) connection when
non-WPA open mode selected for the connection.
- Read mult-link connection info from NL80211_CMD_CONNECT event and copy
to corresponding wpa_s instance.
- Hold the all the associated link BSSes scan results till the
connection is active.
- Authorize supplicant port for AP MLD address after successful
connection.
