Anyway, the point here is the crc32c is nothing special.  It's
just one out of many algorithms that has/will have hardware
acceleration support.

Rather than doing ad-hoc implementations and optimising that
whenever such a thing pops up, let's spend our effort in creating
a common platform that can be reused.

Cheers,
