Hmm, how user land can perform this task then ?

Is there an open source implementation of UDPCP ?

What are its problems ? You say its dog slow, I really wonder why.
UDP stack is pretty scalable these days, yet some improvements are
possible.

Why not adding generic helpers if you believe you miss some
infrastructure ? This could benefit to other 'stacks' as well.

These drivers are here because of high performance on top of high
performance specs.

While UDPCP is only a layer above UDP. If the problem comes from UDP
being too slow, it'll be slow too.
