That's a great idea, Toke.  There are a lot of places where I think it
could work well, especially if it took a pluggable hash function for the
hashing (at which point it's very general-purpose, and works on all sorts
of different kinds of packets and workloads).  That would let it be used
for userspace VPN links (as an example), or within QUIC (or similar), where
the kernel can't see the embedded flows that are hidden by the TLS
encryption.

And having it pluggable in the kernel would also allow IPSec to work
without bloat (last I checked it was horribly bufferbloated, but that was
~5 years ago).
