udev transmits several hashes in order to allow message receivers to use BPF for filtering. This avoids the kernel unnecessarily waking up uninterested processes, which could potentially save performance or power. This is not done by the demo program above.
Implication: The ANE hardware likely has a small set of fixed compute primitives (convolution, matrix multiply, elementwise) that are parameterized by tensor shape descriptors. The E5 binary describes which primitives to chain and how to connect them, not the compute itself.
