I don't think avahi gets a chance to send goodbye packets. More specifically i don't think NM or other mechanism actually tell avahi: Oh we're going to leave the network, please say goodbye and then give it a chance to actually send the necessary goodbyes Yes. The warning (we're changing

2. It takes up to 10min for avahi even to detect the inactivity of a peer. i.e. If an XOs switches channels, for up to 10min avahi wont even know(it used to be 1-2min). Is this with or without the patch from bug #6162 ? If without, then the time it takes avahi to discover it should
