During a LE connection establishment, the host should be able to infer the bdaddr type from a given bdaddr. To achieve that, during the LE scanning, the host stores the bdaddr and the bdaddr type gathered from advertising reports. The host keeps a list of advertising entry (bdaddr and bdaddr_type) for later lookup. This list will be called Advertising Cache. Since the penality to connect to an unreachable device is relatively high, we must keep only fresh advertising entries on the advertising cache. So, before each LE scanning the advertising cache is cleared. Also, after the LE scanning, a timer is set to clear the cache. Next steps include removing all advertising cache from userspace and implementing a mechanism to sync kernel and userspace advertising cache.
