Add new attribute NL80211_ATTR_EMA_RNR_ELEMS to support the above. Number of RNR elements must be more than or equal to the number of MBSSID elements. This attribute can be used only when EMA is enabled. Userspace is responsible for splitting the RNR into multiple elements such that each element excludes the non-transmitting profiles already included in the MBSSID element (%NL80211_ATTR_MBSSID_ELEMS) at the same index. MAC80211 will generate EMA beacons by adding MBSSID and RNR elements at the same index. If the userspace provides more RNR elements than the number of MBSSID elements then these will be added in every EMA beacon.
