Killer NIC is just a weak implementation of a TCP offload Engine (ToE), it
doesn't help for UDP as all the same overheads are still present.  Mellanox
and Solarflare's solutions are about moving everything to user-space
removing the overhead of kernel context and using high performance NICs with
DMA to and from user-space buffers to keep control of the IP stack in
the administrators hands.

Check the Google presentation from Solarflare a while back:
