Hence, When antenna set/get is received we adjust the set/get based on max radio capability and set/get antenna accordingly. Multi radio capability needs to introduced with interface combination changes to support single wiphy model in cfg80211 which would help extend the wiphy specific get/set configs similar to this to per hw level.
