Compared to ieee80211_beacon_get(), the new function ieee80211_beacon_get_tim() returns information on the location and length of the TIM IE, which some drivers need in order to generate the TIM on the device. The old function, ieee80211_beacon_get(), becomes a small static inline wrapper around the new one to not break all drivers.
