[PATCH v2 11/15] nl80211: Handle scan results with MLD connection

From: Ilan Peer <ilan.peer at intel.com>

With an MLD connection the BSSID reported in the association
event is the MLD AP address, while the association state reported
in the scan results relates to the MLD AP specific link. In such a
case do not disconnect.
