This message gets logged far too often for how interesting is it.

Most distributions nowadays configure NetworkManager to use randomly
generated MAC addresses for Wi-Fi network scans. The interfaces end up
being periodically brought down for the address change. When they're
subsequently brought back up, the message is logged, eventually flooding
the log.

Perhaps the message is not all that helpful: it seems to be more
interesting to hear when the addrconf actually start, not when it does
not. Let's lower its level.

This has always bugged me too.

Applied, thanks!
