Detailed Description

Test the calculation of the largest idle primary channel performed by ChannelAccessManager::GetLargestIdlePrimaryChannel().

In every test, the ChannelAccessManager is notified of a CCA_BUSY period and subsequently of the start of RX. The value returned by GetLargestIdlePrimaryChannel() is checked at different times and for different intervals. All the possible combinations of operating channel width and busy channel type are tested.
