EMA profile periodicity equals the count of elements. - ieee80211_beacon_get_template_ema_list() - Generate and return all EMA beacon templates. Drivers must call ieee80211_beacon_free_ema_list() to free the memory. No change in the prototype for the existing API, ieee80211_beacon_get_template(), which should be used for non-EMA AP. - ieee80211_beacon_get_template_ema_index() - Generate a beacon which includes the multiple BSSID element at the given index. Drivers can use this function in a loop until NULL is returned which indicates end of available MBSSID elements. - ieee80211_beacon_free_ema_list() - free the memory allocated for the list of EMA beacon templates.
