NAME
       cfg80211_check_combinations - check interface combinations

SYNOPSIS
       int cfg80211_check_combinations(struct wiphy * wiphy, const int num_different_channels,
                                       const u8 radar_detect,
                                       const int iftype_num[NUM_NL80211_IFTYPES]);

ARGUMENTS
       wiphy
           the wiphy

       num_different_channels
           the 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.

DESCRIPTION
       This function can be called by the driver to check whether a combination of interfaces and
       their types are allowed according to the interface combinations.
