For any n (which would mean any GF field)?  In that case, that is
generic scalar-vector multiplication...
  
Ok. I think I got it. Vectors are things that depend on position inside
buffer and scalars are things that don't, am I right? In that sense we
don't have any vector-vector multiplication. Both async_gen_syndrome()
and async_pq() use constant coefficients. So I don't really understand
the problem here.
Perhaps the interface is just too confusing (in which case it needs to
at least be better documented), but at least the synchronous simulation
code looked like it was doing a vector-vector multiply.
