+ * for the non preferred channels. the distribution of the channel type is:-
+ * Example:- If the percentage of lets say DFS channels is set to 50%, and
+ * the weight comes out to be x, then we would increase the weight of DFS
+ * channels by 50% ( 100 - y% set in INI), so that it gets de-prioritized in
+ * the ACS sorted channel list, the lesser the weight, the better the channel.
+ * So the channel with more weight is less likely to be selected. So by default
+ * the np chan weightage for DFS is set to 0, that is it will be assigned max
+ * weightage, so no probality of getting selected, as for standlaone, DFS is not
+ * recommended (it takes 60 sec/10min to start depending upon channel type).

+ * Indexes are defined in this way.
