Randy,
That's great. Let me know how I can help you to get started. It sounds
like you're already familiar with NetBSD, how and where we communicate,
etc.
BTW, we have a lockless queue in NetBSD called pcq(9). People will
disagree whether it is the best/only lockless queue for the purpose of,
say, SMP networking. pcq(9) uses a fixed-size ring buffer, which may be
advantageous in some scenarios and a liability in others.
We are notably lacking a fast *linked* FIFO queue---i.e., one that can
take the place of struct ifqueue/IF_ENQUEUE()/IF_DEQUEUE() for mbuf
queues.
