const TUint8 KAFHMinUnknownChannels;

Description

Required number of unknown channels in an AFH Host Channel Classification.

That is least number of channels in the 79 channel set that must be left NOT set to bad. In AFH host channel classification a channel may labelled 'bad' (implies do not use) or 'unknown' (implies that it is up to the controller to decide if should be used).
