This documents new DBus property that expose a bit more control to
how IWD roams.
Setting the affinity on the connected BSS effectively "locks" IWD to
that BSS (except at critical RSSI levels, explained below). This can
be useful for clients that have access to more information about the
environment than IWD. For example, if a client is stationary there
is likely no point in trying to roam until it has moved elsewhere.
A new main.conf option would also be added:
[General].CriticalRoamThreshold
This would be the new roam threshold set if the currently connected
BSS is in the Affinities list. If the RSSI continues to drop below
this level IWD will still attempt to roam.
The Changed() method did not actually return anything, and in fact the
no_reply flag for that message was set.
Similarly, the Release method does not expect a reply.
When the SignalLevelAgent doc blurb was moved to station-api.txt it
seems the interface was changed to Station.SignalLevelAgent in some
places but not in most and not in the code. Also fix the pointers to
the doc file.
Station was really a misnomer, it should have been AccessPoint. Also
mark the API as experimental. It will be moved to the Diagnostics
interface eventually.
