During the roam scan, if there are no desired APs found in the partial
frequency list, an immediate full scan on all the supported frequencies
is initiated as a fallback. This flag controls the frequency list
creation for full scan on the following lines.
1 - Full scan to exclude the frequencies that were already scanned by
the previous partial scan.
0 - Full scan to include all the supported frequencies irrespective of
the ones already scanned by partial scan.
