Problem with this conversion, a huge regression for user space.
Using hwrng is simple as cat /dev/hwrng.
Using algif_rng via AF_ALG is ... unusable for the moment.
Perhaps creating an user space tool (prng-tool which provide a cat
/dev/hwrng replacement) is mandatory before any convertion.

Stephan may have a tool to do this.  Stephan?

Here is a suggestion for such a tool that I could add to libkcapi. Naturally, 
this code is only a demonstrator which lacks some features.

Ciao
Stephan
