Do you have any comments specifically about using an inner blkcipher
instance to implement the aead?

Indeed, the inner block cipher looks superfluous since it's only
used once by ccm and there is no nesting similar to aesni-intel.

Inner algorithms are only needed if you want to nest it, e.g.,
through fpu().  Otherwise I don't see any difference vs. calling
the underlying functions directly, especially since you seem to
be calling them directly anyway.

Cheers,
