wiphythe wiphy
num_different_channelsthe number of different channels we want to use for verification
radar_detect
     a bitmap where each bit corresponds to a channel
     width where radar detection is needed, as in the definition of
     struct ieee80211_iface_combination.radar_detect_widths
    
iftype_num[NUM_NL80211_IFTYPES]array with the numbers of interfaces of each interface type. The index is the interface type as specified in enum nl80211_iftype.
