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.

Regards,
Arend
