The previous name packet queue 2 had no indication on what the difference was compared to the regular packet queue. This rename makes it easier to understand the codebase. Additionally the PacketQueueInterface class was introduced to make the class hierarchy easier to follow. The round robin packet queue did not extend the packet queue so there was no reason for inheriting from the specific implementation.
