Question for Herbert...
But the problem I see is that it confuses people, it simply
returns fail everytime (except Blackfin platform).

My mail originates from bug report "tcrypt tests started failing",
and it was not obvious why (for people not familiar with tcrypt
internals, they just tried all test modes available).

Sure, my question was just about test vector, hw driver support
for something more is of course good thing.

But it would be nice to have "crc32c" directly supported/accelerated as well.
