When you try to create an IBSS network with a lot of nodes
you typically end up with split networks due to the fact that
some nodes for one reason or another end up not listening to
beacons from the node others do with a higher TSF. What ends
up happening is you split the IBSS network and these do not
converge. To address this you can force the BSSID as well as
the SSID but if you just want to specify the SSID you can
use the ibss_merge knob to force an IBSS merge by focing the
BSSID to be based on the passed SSID.

Ivan, I think this is what you were looking for but an alternative to this
problem is to specify the BSSID every time you want to create your own large
IBSS network, this would mean that its a requirement and also means we
acknowledge a limitation by IEEE's adhoc definition. Is there any reason
forcing a BSSID on the experimenter is not an equally good solution?

Even setting "fixed-bssid" is acknowledging that already, but I really
see no reason for this to live in the kernel.

Agreed, I was just hoping Ivan can test that does indeed fix that
issue and we can throw this out as one of those "bogus" features
MadWifi had for researchers.
