From: Antonio Quartulli <antonio@xxxxxxxxxxxxx>
The current behaviour when not finding the cbss in the local
list is to always scan before creating the IBSS. However if
bssid and freq have been provided (and fixed_freq is set) it
is possible to immediately create the cell and avoid wasting
time with the scan operation.
