[Ovmsdev] Reducing wifi/netmanager log messages

[Mark Webb-Johnson]

Steve,

Presumably, you are set to connect to a particular wifi access point? (not scanning client mode).

It would be good to suppress the netmanager work if the link was already disconnected (or suppress the messages if the interface priority doesn’t change, as a more general solution?). Same for the STA disconnection.

Regards, Mark.
