Sorry if I'm missing something: Any reasons for which you chose a
different algorithm from the one described in
draft-gont-6man-flowlabel-security?

The algorithm in the aforementioned I-D has already been well tested for
randomizing TCP port numbers, timestamps, and sequence numbers. -- and I
don't think there's a real need to reinvent the wheel.

Thanks,
