That would still break older userspace though, it would get the default channel instead of the channel it set before, right? > >> Also, with IBSS the desired channel is pushed to the driver along with > >> the setup parameters.

I just did this a bit for AP mode. Now, in AP mode we have one advantage: we can rely on userspace setting the channel because hostapd/wpa_s always does that. For mesh, we may not have that luxury? For AP, it looks roughly like this: http://p.sipsolutions.net/35913f571ea5bd43.txt Maybe we can do something similar for mesh and mostly get rid of setting the channel directly. johannes _______________________________________________ Devel mailing list [email protected] http://lists.open80211s.org/cgi-bin/mailman/listinfo/devel
