 *
 * This INI give percentage value of weights to be considered in the ACS algo
 * 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.
 *     0 Index (BITS 0-7): DFS - Def 1%
 *     1 Index (BITS 8-15): Reserved
