Hi Johannes,My brain is tripping over a field in struct ieee80211_iface_combination, ie. the num_different_channels. Looking at the name I tend to think that num_different_channel = 0 means the interfaces must all operate on the same channel. However, in most places it is configured as 1 or more. The documentation in cfg80211.h [1] is not unambiguous about it in my opinion. By now it probably depends on how user-space uses it.
