But in the practice this is not a bug, it's an optional feature and you can mix nodes with fixed BSSID and nodes without, so that the backbone nodes (routers) force the rather client nodes (e.g. notebooks) to use this BSSID, so that the mesh network don't break into many pieces. That was happen many times before we use a fixed BSSID.
You don't need to use it, if you don't want it, but we must use it, or it will not work.

It's a little modified IBSS, that allow you to build bigger networks. Not a huge change, that is completely incompatible with the standard.

I can call it Moonchild , if you want. ;)
I don't care on the name of it.

I don't introduce setting of a fixed BSSID with this patch, I only fix some bugs of the current implementation.
