+Subject: [PATCH] brcmfmac: rework .get_station() callback
+
+The .get_station() cfg80211 callback is used in several scenarios. In
+managed mode it can obtain information about the access-point and its
+BSS parameters. In managed mode it can also obtain information about
+TDLS peers. In AP mode it can obtain information about connected
+clients.
