We defined async_pq() function as hardware can do GF multiplication of
arbitrary elements and we want to take advantage of this fact. But by
the design of ASYNC_TX API we have to provide synchronous version of
that function too.


I don't think that makes sense since the algorithm doesn't use vector-vector multiplications and there is no need for them. As such, you're actively excluding support for hardware which only provides scalar-vector multiplication, even though that is all we need.

In fact, vectorizing the constant doesn't make much sense.
