This interface would expose details are may be too low level for a
general purpose application, like a connection manager. Some of these
details are useful though and these will go into this new diagnostic
interface. This interface is also going to be very useful in the
autotesting framework.
The GetDiagnostics() method is somewhat mapped to GET_STATION in
nl80211. Some of these values are too volatile to express as properties
as they change frequently so an application may get them at the time
they are needed.
The additional properties would be purely for autotesting/debugging.

+Station diagnostic hierarchy
+=================
+
+Service net.connman.iwd
+Interface net.connman.iwd.StationDiagnostic
+Object path /net/connman/iwd/{phy0,phy1,...}/{1,2,...}
+
+Methods dict GetDiagnostics()
+
+ Get all diagnostic information for this interface. The
+ diagnostics are contained in a single dictionary. Values
+ here are generally low level and not meant for general
+ purpose applications which could get by with the
+ existing Station interface or values which are volatile
+ and change too frequently to be represented as
+ properties. The values in the dictionary may come and
+ go depending on the state of IWD.
+
+ Below is a list of possible diagnostic values:
+
+ ConnectedBss - MAC address of currently connected BSS.
+
+ RSSI - The RSSI of the currently connected BSS.
+
+ RxRate - Receive rate in MBit/s
+
+ TxRate - Transmission rate in MBit/s
+
+ Others may include: channel, country code, security,
+ noise, phy mode, MCS index.
+
+RFC: These are some ideas I was playing around with for auto-testing. They
+ are only useful as properties since autotests would rely on the
+ PropertiesChanged signal. These would give the autotest framework much
+ finer detail into whats going on, rather than only knowing if the
+ connection succeeded or failed.
+
+Properties string ConnectionState [readonly]
+
+ The state of an ongoing connection attempt. This state
+ reflects the sub-states between the Station interface
+ states of "connecting" and "connected":
+
+ "authenticating", "associating", "handshaking",
+ "connected", "disconnected".
+
+ uint16 ConnectFailedReasonOrStatus [readonly]
+
+ The reason or status code returned from a failed
+ connection attempt. The 'ConnectionState' will indicate
+ if this value is a Reason code or Status code.
