No, this has nothing to do not supporting IBSS but instead you should read "no IBSS" more as a regulatory rule that implies you cannot use a mode of operation that can beacon. We should at least rename this on iw for now to make thins clearer. What you see should be part of the default rules embedded on the device's EEPROM. Beaconing is allowed on channel 11 even on the most restrictive regulatory domain and this is why the world regulatory domain allows 1-11 to beacon too. You should enable debugging on the driver upon load to confirm whether this rule is coming from the EEPROM. Do you have CONFIG_WIRELESS_OLD_REGULATORY? I think even that (by default it used the US) enabled beaconing. Drivers can overrule things though if their EEPROM mandates this. Luis
