This is a new fairer queue than the existing FIFO queue.
Rather than just having a single queue per peer, we have 32 of them, each able to hold 255 frames. Traffic is divided up into queues based on the source keys. If a queue is full, new frames will be dropped.
We'll pull traffic off queues at random so this means that specific flows of traffic can't exhaust all available buffer space for a peer.
