My understanding was that QUIC focuses purely on userland implementations this is interesting.
Since understanding how the Windows kernel works is on my ToDo list for next life,
can you explain how they do the public crypto operations in the kernel without
risking CPU exhaustion attacks (last time I checked, these were expensive).

Is there really a demand for kernel based QUIC stacks?
